CITATION LIST
PATENT LITERATURE
SUMMARY OF INVENTION
PROBLEM TO BE SOLVED BY THE INVENTION
[0004] Future aerosol-generating devices are expected to employ contact sensors. The use of contact sensors can offer the user novel ways of using the aerosol-generating device.
On the other hand, contact sensors are devices with which there is no mechanical displacement accompanying input of actions. When a contact sensor is used in an aerosol-generating device, it is therefore difficult for the user to actually appreciate whether or not their action is being detected or whether their action has been accepted in the normal manner.
[0005] In light of the problem above, the present disclosure provides technology capable of providing a user with an actual feeling of inputting an action, even when a contact sensor is used as the input device.
SOLUTION TO PROBLEM
[0006] One aspect of the present disclosure provides an aerosol-generating device comprising: a heating unit for heating an aerosol source; a contact sensor for detecting a user action on a predetermined part of a housing surface; a haptic device; and a processor for implementing a function to control heating of the aerosol source by the heating unit, and a function to control output of the haptic device, wherein the processor controls the output of the haptic device by switching said output in accordance with content which is notified.
[0007] Moreover, the processor may control an output intensity of the haptic device to a first output intensity when detection of the start of an action is notified.
[0008] The processor here may control the output intensity of the haptic device to a second output intensity greater than the first output intensity when completion of acceptance of an action is notified.
[0009] Furthermore, the processor here may control the output intensity of the haptic device to a second output intensity greater than the first output intensity when an operating mode is a heating mode of the aerosol source.
[0010] Furthermore, the processor here may control the output intensity of the haptic device to a second output intensity greater than the first output intensity when occurrence of an error is notified.
[0011] Additionally, the processor may vary a number of times of output in accordance with the content which is notified while keeping the output intensity of the haptic device at a third output intensity, when acceptance of a switching-related action is notified.
[0012] Furthermore, the processor may vary the output intensity while keeping the number of times of output of the haptic device fixed, when acceptance of a switching-related action is notified.
[0013] The switching-related action is an action to modify at least one of a heating temperature, brand of aerosol source, heating profile, display mode, inhalation detection sensitivity, display color, preheating time, heating time, and output, for example.
[0014] The processor here may vary the output intensity of the haptic device in accordance with a heating temperature of the aerosol source, when the heating temperature is notified.
[0015] Additionally, the processor may vary the output intensity of the haptic device or may vary the number of times of output in accordance with a quantity or number to be notified, when acceptance of a checking-related action is notified.
[0016] The checking-related action here is an action to check at least one of remaining capacity in a battery constituting an electrical power source, charging status of the battery, lifespan of the battery, number of times of inhalation, remaining number of inhalations, remaining inhalation time, remaining number of times of inhalation, cumulative number of times of inhalation, remaining amount of the aerosol source, and completion of replacement of the aerosol source, for example.
[0017] Additionally, the processor may control the haptic device to output using a first output pattern, when detection of the start of an action by the contact sensor is notified.
[0018] The processor here may control the haptic device to output using a second output pattern different from the first output pattern, when completion of acceptance of an action by the contact sensor is notified.
[0021] Furthermore, the processor may control the output intensity, number of times of output, or output pattern of the LRA by switching the relevant output in accordance with notification content.
[0023] Moreover, the processor may comprise: a first processor for controlling heating of the aerosol source by the heating unit; and a second processor for controlling output of the haptic device.
ADVANTAGEOUS EFFECTS OF INVENTION
[0024] According to one aspect of the present disclosure, it is possible to provide a user with an actual feeling of inputting an action, even when a contact sensor is used as the input device.

EMBODIMENTS OF THE INVENTION
[0026] Embodiments relating to the present disclosure will be described below with reference to the drawings. In the drawings, identical parts are indicated by identical reference signs.
<Terms>
[0027] An aerosol-generating device according to each embodiment is a form of electronic cigarette.
In the following description, a substance generated by the aerosol-generating device will be referred to as an aerosol. An aerosol refers to a mixture of minute liquid or solid particles suspended in a gas, and air or another gas.
The embodiments describe aerosol-generating devices which generate the aerosol without associated burning.
[0028] Moreover, inhalation of the aerosol generated by the aerosol-generating device will also be referred to as a "puff".
In each embodiment, an aerosol-generating device to which it is possible to attach a solid aerosol source is described. It should be noted that a container for accommodating the solid aerosol source will be referred to as both a "capsule" and a "stick-type substrate", depending on the form of product. Capsules and stick-type substrates are consumables. Capsules and stick-type substrates therefore have fixed criteria for replacement.
<Embodiment 1>
[0029] Embodiment 1 describes an aerosol-generating device of the type in which a stick-type substrate accommodating a solid aerosol source is heated at a high temperature (e.g., 200°C or greater).
<Example of external appearance>
[0030] An example of the external appearance of an aerosol-generating device used in Embodiment 1 will first be described.
Fig. 1 is a diagram in which a front face side of an aerosol-generating device 1 envisaged by Embodiment 1 is seen from diagonally above.
The aerosol-generating device 1 used in this embodiment has a size such that a user can hold it in one hand. The aerosol-generating device 1 comprises a main body portion 10 and a slide cover 20.
[0031] The main body portion 10 is essentially a solid object with six faces. Specifically, each face of the main body portion 10 is connected to another adjacent face by a curved surface. An opening 10A (not depicted here; see fig. 2) for attachment/detachment of a cylindrical stick-type substrate 30 (see fig. 3) is provided in an upper face of the main body portion 10.
[0032] The external appearance of the main body portion 10 is defined by surfaces of a housing. The main body portion 10 is divided into an inside space and an outside space by the housing. The entire surface of the main body portion 10 will also be referred to as the "housing surface" in this embodiment. Furthermore, one part of the surface of the main body portion 10 will also be referred to as a "housing face".
The slide cover 20 is a component capable of sliding along the upper face of the main body portion 10. In the case of fig. 1, the opening 10A is covered by the slide cover 20. A state in which the opening 10A is covered by the slide cover 20, as shown in fig. 1, is referred to as a "closed state". Furthermore, a sliding position of the slide cover 20 in this state is referred to as a "closed position".
[0033] Fig. 2 is a diagram to illustrate a state in which the opening 10A is exposed by sliding of the slide cover 20. Corresponding reference signs are given in fig. 2 for parts that correspond to those of fig. 1. As shown in fig. 2, a state in which the opening 10A is exposed is referred to as an "open state". Furthermore, a sliding position of the slide cover 20 in this state is referred to as an "open position".
The opening 10A forms an opening end of a substantially cylindrical holding portion 109 (see fig. 3) in which the stick-type substrate 30 is held. The opening 10A therefore has a substantially circular shape. The slide cover 20 shown in fig. 2 is slid along a guide groove (not depicted) formed on the upper face of the main body portion 10 or a rear side thereof.
The face on which the thumb is positioned when the main body portion 10 is gripped in the right hand with the slide cover 20 positioned on top will be referred to below as the front face. In other words, the face facing the user when the opening 10A is positioned on the left side of the main body portion 10 from the user's perspective refers to the front face.
<Internal configuration>
[0034] Fig. 3 is a diagram schematically showing an internal configuration of the main body portion 10. The stick-type substrate 30 is mounted in the opening 10A of the main body portion 10 shown in fig. 3.
The internal configuration shown in fig. 3 is intended to illustrate the components provided in the main body portion 10 and positional relationships therebetween. For this reason, the external appearance of the components, etc. shown in fig. 3 does not always match the external views described above.
[0035] The main body portion 10 is configured by a power source unit 101, a sensor unit 102, a notification unit 103, a memory unit 104, a communication unit 105, a control unit 106, a heating unit 107, a heat insulating portion 108, and a holding portion 109.
The stick-type substrate 30 shown in fig. 3 is held in the holding portion 109. The user inhales the aerosol while the stick-type substrate 30 is fitted in the holding portion 109.
[0036] The power source unit 101 is a unit for supplying power to each component. The power source unit 101 uses a secondary battery to store power required by the main body portion 10. A lithium ion secondary battery is used as the secondary battery, for example. The secondary battery can be charged from an external power source. In the case of Embodiment 1, the external power source is connected via a USB connector which is not depicted. The USB connector is provided on a bottom face of the main body portion 10, for example.
[0037] The sensor unit 102 is an electronic component for detecting various types of information relating to the main body portion 10.
The sensor unit 102 is a magnetic sensor used to detect the sliding position of the slide cover 20 (see fig. 1), for example. The magnetic sensor is placed within the movable range of the slide cover 20 and detects the intensity of a magnetic field commensurate with the sliding position of the slide cover 20. Incidentally, the magnetic field to be detected is generated by a magnet attached to the slide cover 20. The control unit 106 detects whether the sliding position of the slide cover 20 is the open position or the closed position by means of magnetic field intensity information notified from the magnetic sensor.
[0038] The sensor unit 102 includes a pressure sensor such as a microphone capacitor, or a flow rate sensor, for example. The flow rate sensor notifies the control unit 106 of information indicating a change in air pressure or a flow of air accompanying inhalation, for example.
The sensor unit 102 is a contact sensor for detecting input of user actions, for example. A touch sensor 102A (see fig. 4) is used as the contact sensor in this embodiment. The touch sensor 102A is provided on a predetermined part of the housing surface used for inputting actions. In the case of this embodiment, the touch sensor 102A is a sensor for detecting contact of the user's hand or finger, etc. as a change in electrostatic capacitance, and is arranged on a rear face side of the housing corresponding to the predetermined part. The control unit 106 detects input of user actions by means of information on the change in electrostatic capacitance notified from the touch sensor 102A. The information on the change in electrostatic capacitance includes not only a coordinate position where contact has been detected, but also a transition thereof (or trajectory of movement), movement speed, and contact time, etc.
[0039] The sensor unit 102 additionally includes a temperature sensor for detecting the temperature of the heating unit 107, for example. The temperature sensor detects the temperature of the heating unit 107 on the basis of a change in an electrical resistance value of an electrically conductive track of the heating unit 107, for example. The temperature sensor outputs a voltage corresponding to the electrical resistance value at the current time. The control unit 106 calculates the temperature of the heating unit 107 from the output voltage from the temperature sensor. The temperature sensor is used for the purpose of varying the temperature of the heating unit 107 in accordance with a heating profile. Other temperature sensors include a temperature sensor for detecting the temperature around the heating unit 107 and a temperature sensor for detecting the temperature near the surface of the main body portion 10. These two temperature sensors are used from the viewpoint of detecting an unexpected increase in temperature. In other words, these temperature sensors are provided from the viewpoint of safety.
[0040] The notification unit 103 is an electronic component for notifying the user of various types of information relating to the main body portion 10. The notification unit 103 is a vibration device, etc. which causes the main body portion 10 to vibrate, for example. The vibration device is a vibration motor 103A (see fig. 4), for example. A linear resonant actuator (LRA) is used as the vibration motor 103A in this embodiment. The LRA is an actuator of the linear resonance type. The LRA generates vibration perceptible to the user by driving a voice coil at the resonant frequency of a spring. This vibration is perceived by the user through the skin. In this regard, the vibration motor 103A is an example of a haptic device.
A sound output device that outputs sound is an example of another notification unit 103. The sound output device may be configured by a speaker and an amplifier, for example.
[0041] Fig. 4 is a diagram to illustrate the positional relationship of the touch sensor 102A and the vibration motor 103A in Embodiment 1. The touch sensor 102A and the vibration motor 103A are both provided in the inside space of the housing of the main body portion 10. In fig. 4, the attachment positions of the touch sensor 102A and the vibration motor 103A are therefore depicted by broken lines.
In fig. 4, the touch sensor 102A has a substantially square shape. The touch sensor 102A shown in fig. 4 is placed close to the center of the front face of the main body portion 10.
[0042] The touch sensor 102A is placed in a range where tapping or swiping with the thumb is possible while the main body portion 10 is gripped in the right hand. The touch sensor 102A shown in fig. 4 is therefore placed to the upper face side of the center in the height direction of the main body portion 10. A digit other than the thumb may naturally be used for input actions.
The dimensions of the touch sensor 102A are set in accordance with the thumb movements envisaged for input of actions. For example, the dimensions of the touch sensor 102A required when only tapping actions are envisaged are smaller than the dimensions of the touch sensor 102A required when swiping actions are envisaged.
[0043] Moreover, when swiping actions in a left-right direction (the X direction in fig. 4) are envisaged as input actions, the X-direction dimension may be longer than the Z-direction dimension, and when swiping actions in an up-down direction (the Z direction in fig. 4) are envisaged, the Z-direction dimension may be longer than the X-direction dimension. Swiping actions in the horizontal direction and the vertical direction are also envisaged in this embodiment, in addition to tapping actions. The substantially square touch sensor 102A is therefore used.
In the case of this embodiment, the vibration motor 103A is arranged close to the touch sensor 102A. Incidentally, fig. 4 shows a situation in which the vibration motor 103A is arranged close to the center of the touch sensor 102A.
[0044] However, the touch sensor 102A and the vibration motor 103A cannot physically be placed in the same space. The actual vibration motor 103A is therefore arranged on the rear side of the touch sensor 102A as seen from the front face of the main body portion 10.
Fig. 5 is a diagram to illustrate the relationship of mounting positions of the touch sensor 102A and the vibration motor 103A. Fig. 5 shows the positional relationship as seen through the inside of the main body portion 10 from the right face side.
[0045] In the case of fig. 5, the vibration motor 103A is positioned inwardly from the touch sensor 102A. In other words, the vibration motor 103A is positioned on the rear face side of the touch sensor 102A.
In this embodiment, differences in vibration intensity are more readily transmitted to the user by reducing the distance between the vibration motor 103A and the touch sensor 102A.
[0046] The memory unit 104 is an electronic component for storing various types of information relating to operation of the main body portion 10. The memory unit 104 is configured by a nonvolatile semiconductor storage medium such as a flash memory, for example.
Information stored in the memory unit 104 includes an OS (= operating system) and FW (= firmware), and other programs, for example.
Furthermore, the information stored in the memory unit 104 includes information relating to control of electronic components, and information relating to user inhalation, for example. The information relating to control includes heating profiles, for example. The information relating to user inhalation includes number of times of inhalation, times of inhalation, and cumulative inhalation time. The information relating to user inhalation is also referred to as an operation log.
[0047] The communication unit 105 is a communication interface for implementing communication between the main body portion 10 and other devices. The communication unit 105 communicates with other devices by means of a system based on any wired or wireless communication standard. Examples of communication standards as referred to here include wireless LAN (= local area network), USB, Wi-Fi (registered trademark), and Bluetooth (registered trademark).
For example, the communication unit 105 sends the information relating to user inhalation to a smartphone. Furthermore, the communication unit 105 downloads, from a server, update programs and heating profiles defining changes in the temperature of the heating unit 107 in a heating mode.
[0048] The control unit 106 functions as an arithmetic processing device and a control device, and controls operations of the components constituting the main body portion 10 in accordance with various programs.
Control signals are sent through signal lines different from power supply lines. For example, communication in the main body portion 10 employs a serial communication method such as an I2C (= inter-integrated circuit) communication method, an SPI (= serial peripheral interface) communication method, or a UART (= universal asynchronous receiver transmitter) communication method.
[0049] The control unit 106 is realized by means of an electronic circuit such as a CPU (= central processing unit), an MCU (= microcontroller unit), an MPU (= microprocessing unit), a GPU (= graphical processing unit), an ASIC (= application-specific integrated circuit), an FPGA (= field programmable gate array), or a DPS (= digital signal processor), for example. The control unit 106 is an example of a processor.
The control unit 106 may also include a ROM (= read only memory) for storing programs and computation parameters, etc., and a RAM (= random access memory) for temporarily storing suitably changing parameters, etc.
[0050] The control unit 106 executes various types of processing and control through execution of programs.
The processing and control referred to here include, for example: supply of electricity by the power source unit 101; charging of the power source unit 101; detection of information by the sensor unit 102; notification of information employing the notification unit 103; writing of information to the memory unit 104 or reading of information from the memory unit 104; and sending/receiving of information employing the communication unit 105.
The control unit 106 additionally controls processing, etc. based on input of information to the electronic components and information output from the electronic components.
[0051] The holding portion 109 is a substantially cylindrical container. In this embodiment, a space inside the holding portion 109 defined by an inner wall and a bottom face will be referred to as an internal space 109A. The internal space 109A is substantially columnar. An opening end of the holding portion 109 corresponds to the opening 10A which is exposed by a sliding operation of the slide cover 20. The stick-type substrate 30 is inserted into the internal space 109A from the opening 10A. It should be noted that the stick-type substrate 30 can be inserted until the tip end thereof touches a bottom portion 109B.
The stick-type substrate 30 is only partially accommodated in the internal space 109A. A state in which the stick-type substrate 30 is accommodated in the internal space 109A will be referred to as the stick-type substrate 30 being held in the internal space 109A.
[0052] The inner diameter of the substantially cylindrical holding portion 109 is roughly the same as the outer diameter of the stick-type substrate 30. However, the inner diameter of at least part of the holding portion 109 in an axial direction thereof is formed so as to be smaller than the outer diameter of the stick-type substrate 30.
At that position, the outer circumferential surface of the stick-type substrate 30 is subjected to pressure from the inner wall of the holding portion 109. The stick-type substrate 30 deforms and is held in the internal space 109A by means of this pressure.
The holding portion 109 also has a function of defining a flow path for air passing through the stick-type substrate 30. An air inflow hole, which is an inlet for air into the flow path, is disposed in the bottom portion 109B, for example. Moreover, the opening 10A serves as an air outflow hole, which is an outlet for the air.
[0053] In the case of this embodiment, only part of the stick-type substrate 30 is held in the internal space 109A, with the remainder protruding outside from the housing. The part of the stick-type substrate 30 which is held in the internal space 109A will be referred to below as a substrate portion 30A, and the part protruding from the housing will be referred to below as a mouthpiece portion 30B.
The aerosol source is accommodated in at least the substrate portion 30A. The aerosol source is a substance which is atomized by heating so as to generate an aerosol.
The aerosol source includes cut tobacco, and also processed products obtained by molding a tobacco raw material into a granular form, a sheet form or a powder form, or other tobacco-derived substances.
[0054] In addition, the aerosol source may also include non-tobacco-derived substances produced from plants other than tobacco, such as mint or herb. The aerosol source may include a flavoring component such as menthol, for example.
When the main body portion 10 is a medical inhaler, the aerosol source may include a drug to be inhaled by a patient. It should be noted that the aerosol source is not limited to a solid, and may equally be a polyhydric alcohol such as glycerol or propylene glycol, or may be a liquid such as water, for example.
[0055] At least part of the mouthpiece portion 30B is held in the user's mouth during inhalation. When the user inhales with the mouthpiece portion 30B held in their mouth, air flows into the internal space 109A from the air inflow hole. The air that has flowed in reaches the user's mouth after passing through the internal space 109A and the substrate portion 30A. The air reaching the user's mouth contains the aerosol generated by the substrate portion 30A.
[0056] The heating unit 107 is formed by a heater or other heat-generating element. The heating unit 107 is formed by any material such as a metal or polyimide. The heating unit 107 is constructed in the form of a film, for example, and is fitted to an inner wall surface of the holding portion 109 defining the internal space 109A.
The aerosol source contained in the stick-type substrate 30 is heated and atomized by the heat generated by the heating unit 107. The atomized aerosol source is mixed with air, etc., and an aerosol is generated.
In fig. 3, the outer circumferential region of the stick-type substrate 30 is initially heated, with the range of heating steadily moving toward the center.
[0057] Atomization of the aerosol source therefore starts from the outer circumferential region of the stick-type substrate 30 and steadily moves toward the center.
The heating unit 107 generates heat by means of electrical supply from the power source unit 101. Electrical supply to the heating unit 107 is permitted when a predetermined user action has been detected by means of the sensor unit 102, for example. Predetermined user actions here include the action to open/close the slide cover 20 (see fig. 1), and an action on the contact sensor (e.g., the touch sensor 102A).
[0058] Moreover, inhalation by the user becomes possible when the temperature of the stick-type substrate 30 heated by means of the heating unit 107 reaches a predetermined temperature. A change over time in the target temperature from the start of heating to the end of heating is stored in the memory unit 104 as a heating profile. The heating profile is an example of a control sequence. Inhalation of the aerosol by the user is sensed by means of the flow rate sensor, etc. in the sensor unit 102 and is saved in the memory unit 104.
Electrical supply to the heating unit 107 is stopped when a predetermined time has elapsed since the start of heating or when a predetermined user action is sensed. The predetermined action is removal of the stick-type substrate 30, for example.
[0059] Furthermore, in the example of fig. 3, the heating unit 107 is disposed at the outer circumferential portion of the stick-type substrate 30, but the heating unit 107 may equally be a blade-like metal piece which is inserted into the stick-type substrate 30.
Alternatively, an induction heating method, for example, may be used to atomize the aerosol source. In this type of heating method, the heating unit 107 has at least an electromagnetic induction source such as a coil that generates a magnetic field. In this case, a susceptor is disposed at a position overlapping the magnetic field generated by the electromagnetic induction source. The susceptor generates heat in association with generation of the magnetic field, and heats the aerosol source. The susceptor may be a metal piece that is built into the stick-type substrate 30. When a metal piece acting as the heating unit 107 is built into the stick-type substrate 30, a coil for inductively heating the metal piece is disposed around the holding portion 109. Alternatively, the susceptor may be disposed at an outer circumferential portion of the stick-type substrate 30 within the main body portion 10, and a coil serving as an electromagnetic induction source may be wound around the outer circumferential portion thereof.
[0060] The heat insulating portion 108 is a member for reducing propagation of heat generated by the heating unit 107 to the surrounding area. The heat insulating portion 108 is therefore disposed so as to cover at least the outer circumferential surface of the heating unit 107.
For example, the heat insulating portion 108 is configured by a vacuum insulating material or an aerogel insulating material, etc. A vacuum insulating material is a heat insulating material in which a state of high vacuum is created by wrapping glass wool and silica (silicon powder), etc. in a resin film, for example, so that heat conduction by gas is as close as possible to zero.
<Operating modes>
[0061] Fig. 6 is a diagram to illustrate a transition between operating modes arranged in the aerosol-generating device 1 (see fig. 1) used in Embodiment 1.
The aerosol-generating device 1 used in Embodiment 1 has nine operating modes. These nine modes are: charging mode M1, sleep mode M2, error modes M3, M4, pairing mode M5, active mode M6, initialization mode M7, heating mode M8, and heating end mode M9.
• Charging mode M1
[0063] Charging mode M1 is a mode in which the secondary battery is charged by using the USB cable. Deep discharge and over-discharge of the secondary battery are also detected in charging mode M1.
• Sleep mode M2
[0064] Sleep mode M2 is a mode in which most functions are stopped. In other words, sleep mode M2 is a mode in which less power is consumed than in other modes.
However, detection of the closed state of the slide cover 20 (see fig. 1), monitoring of the state of the secondary battery, and detection of transitions to other operating modes are possible. Incidentally, a dedicated processor (referred to below as a "remaining capacity meter IC") is used for monitoring the state of the secondary battery. The remaining capacity meter IC is a separate processor from the MCU.
[0065] The transition from charging mode M1 to sleep mode M2 is made, for example, when the USB cable is removed during charging. When a function is provided to warn the user by means of vibration or sound, etc. that the USB cable has been disconnected during charging, the switch to sleep mode M2 need not be made immediately.
The transition from active mode M6 to sleep mode M2 is made, for example, when the slide cover 20 has moved from the open position to the closed position, when a predetermined action has been detected through the touch sensor 102A (see fig. 4), or when a state of non-action persists for a predetermined time or greater.
The transition from sleep mode M2 to active mode M6 is made, for example, when the slide cover 20 has moved from the closed position to the open position, or when an activation action has been detected through the touch sensor 102A.
The transition from sleep mode M2 to charging mode M1 is made, for example, when the USB cable is connected.
• Error mode M3
[0066] Error mode M3 is a mode which appears temporarily when there has been a recoverable error such as a temperature abnormality.
[0067] When there is a transition to error mode M3, an error notification is output and sleep mode M2 is restored after a given time has elapsed or after a predetermined condition resolving the error has been met. Vibration of a given intensity is used for the error notification, for example. The vibration intensity here is an example of second output intensity. Incidentally, the second output intensity is greater than a first output intensity which will be described later.
[0068] There may also be a transition to error mode M3 from charging mode M1, active mode M6, initialization mode M7, and heating mode M8.
• Error mode M4
[0069] Error mode M4 is a mode which appears when there has been a non-recoverable error such as deep discharge, secondary battery lifespan, or short-circuit, for example. Transitions from error mode M4 to other modes are prohibited.
• Pairing mode M5
[0070] Pairing mode M5 is a mode for pairing with an external device, for example. Bluetooth is used for pairing, for example.
[0071] The transition from sleep mode M2 to pairing mode M5 is made, for example, when a pairing action has been detected through the touch sensor 102A.
• Active mode M6
[0072] Active mode M6 is a mode in which most functions apart from heating are available. Active mode M6 enables, for example: sending of heating profiles to an external device; reception of heating profiles from an external device; modification of heating profiles used for heating the stick-type substrate 30 (heating temperature modification); a change of brand of stick-type substrate 30 to be heated; and checking of various types of information, etc.
[0073] The transition from sleep mode M2 to active mode M6 is made, for example, when the slide cover 20 has moved from the closed position to the open position, or when an activation action has been detected through the touch sensor 102A.
[0074] The transition from active mode M6 to sleep mode M2 is made when the slide cover 20 has moved from the open position to the closed position, or when a state of non-action persists for a predetermined time or greater while in active mode M6.
The transition from active mode M6 to initialization mode M7 is made when an action to instruct the start of heating through the touch sensor 102A has been detected while the slide cover 20 is in the open position.
There may also be a transition to charging mode M1 or pairing mode M5 from active mode M6.
• Initialization mode M7
[0075] Initialization mode M7 is a mode which is implemented before heating of the stick-type substrate 30 is started.
[0076] Initial settings and preheating, etc. are implemented in initialization mode M7. In the initial settings, the heating profile used for heating the stick-type substrate 30 is read in, for example. Preheating refers to the stick-type substrate 30 being preheated in order to generate a given amount of aerosol from immediately after the start of heating mode M8.
[0077] Note that initialization mode M7 transitions to error mode M3 if an error occurs during initialization. Examples of errors during initialization include failure to read a heating profile and removal of the stick-type substrate 30.
• Heating mode M8
[0079] The stick-type substrate 30 is heated on the basis of the heating profile. The heating profile defines a relationship between the time elapsed from the start of heating and a target temperature at each time point. The control unit 106 controls the heating unit 107 ON/OFF so that the measured temperature at each elapsed time is consistent with the target temperature. Heat is generated when the heating unit 107 is controlled ON (when the heater is energized), and heat generation is stopped when the heating unit 107 is controlled OFF (when energization of the heater is stopped).
[0080] The transition from initialization mode M7 to heating mode M8 is made by completion of the initial settings. Note that heating mode M8 transitions to error mode M3 if an error occurs during heating. Examples of errors during heating include detection of an abnormal temperature beyond the target temperature, and removal of the stick-type substrate 30.
• Heating end mode M9
[0082] The processing at the end of heating may be updating management data, for example. The management data may include, for example, number of inhalations on the present occasion, cumulative number of inhalations, and cumulative number of stick-type substrates 30.
[0083] The transition from heating mode M8 to heating end mode M9 is made, for example, when a predetermined time defined in the heating profile has elapsed, or when there has been a heating termination action through the touch sensor 102A.
[0084] The transition from heating end mode M9 to active mode M6 is made when the processing at the end has been completed.
<Combinations of input actions and haptic feedback>
[0085] Exemplary combinations of input actions to the touch sensor 102A (see fig. 4) and haptic feedback from the vibration motor 103A will be described below. Four exemplary combinations will be described below for each type of input action. It goes without saying that the exemplary combinations are only examples and should not be construed as excluding other exemplary combinations.
[0086] Only one command can be assigned to one input action in one operating mode. Accordingly, where multiple commands are illustrated for one input action in one operating mode, such illustration is confined to reference examples, and only one of the multiple commands is used for implementation in an actual device.
<Exemplary Combination 1: Tapping action and swiping action>
[0089] It should be noted that linear movements are envisaged for swiping actions in Exemplary Combination 1. Up/down/left/right finger movements are envisaged, for example. Diagonally upward movements and diagonally downward movements may naturally also be combined.
[0090] Only four types of instructions can be assigned to one operating mode when up/down/left/right finger movements are envisaged for swiping actions, but eight types of instructions can be assigned to one operating mode by combining diagonally upward and downward movements.
[0091] Different vibration patterns are used as haptic feedback. Vibration patterns within the broad sense include different numbers of times of vibration with the same vibration intensity (also including different timings of vibration output) and different intensities of vibration with the same number of times of vibration. Acceptance of user actions can be perceived by the user by a difference in vibration pattern.
[0092] Furthermore, the feedback vibration pattern allows the user to anticipate the content of control to be implemented by the control unit 106 (see fig. 3). Additionally, the user is able to confirm the content of the control implemented by the control unit 106 (see fig. 3) and the content of responses by the control unit 106 by means of the intensity of feedback vibration.
<Upward swiping action>
[0093] L1, the first line from the top of the table, illustrates two commands and the vibration pattern associated with an "upward swiping action".
• Example 1 (L1-A)
[0094] For example, when there has been an "upward swiping action" during sleep mode M2, the control unit 106 (see fig. 3) changes from a sleep state to an active state. That is to say, the operating mode is shifted from sleep mode M2 to active mode M6.
[0095] In this case, there is an increase in the intensity of feedback vibration the longer the distance of upward movement of the finger. The movement distance here is an example of notification content. The LRA used as the vibration motor 103A has a fast response speed of approximately 20 ms-30 ms. The vibration intensity therefore gradually increases in proportion to the distance of movement of the finger, making it easier for the user to actually feel that their action is being accepted.
• Example 2 (L1-B)
[0096] For example, when there has been an "upward swiping action" during active mode M6, "send heating profile" is implemented. This action is possible only when the aerosol-generating device 1 (see fig. 1) is compatible with the function for sending heating profiles to an external device. Again, there is an increase in the intensity of feedback vibration the longer the distance of upward movement of the finger. The movement distance here is also an example of notification content.
[0097] It should be noted that when there has been an upward swiping action on an aerosol-generating device 1 which is incompatible with the function for sending heating profiles, this swiping action is treated as invalid, the operating mode is shifted to error mode M3, error vibration (e.g., high-intensity continuous vibration or a distinctive vibration pattern) is fed back, or an error sound is fed back. The intensity of error vibration is an example of second output intensity. Incidentally, the second output intensity is greater than the first output intensity.
<Downward swiping action>
[0098] L2, the second line from the top of the table, illustrates two commands and the vibration pattern associated with a "downward swiping action".
• Example 1 (L2-A)
[0099] For example, when there has been a "downward swiping action" during active mode M6, the control unit 106 changes from an active state to a sleep state. That is to say, the operating mode is shifted from active mode M6 to sleep mode M2. In this case, there is a reduction in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is also an example of notification content.
• Example 2 (L2-B)
[0100] For example, when there has been a "downward swiping action" during active mode M6, "receive heating profile" is implemented. This action is possible only when the aerosol-generating device 1 is compatible with adding or modifying heating profiles. Again, there is a reduction in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is also an example of notification content.
[0101] It should be noted that when there has been a downward swiping action on an aerosol-generating device 1 which is incompatible with the function for receiving heating profiles, this swiping action is treated as invalid, the operating mode is shifted to error mode M3, error vibration is fed back, or an error sound is fed back. The intensity of error vibration here is an example of second output intensity. The second output intensity is greater than the first output intensity.
<Swiping action in both left/right directions>
[0102] L3, the third line from the top of the table, illustrates two commands and the vibration pattern associated with a "swiping action in both left/right directions".
• Example 1 (L3-A)
[0103] For example, when there has been a "swiping action in the right direction" or a "swiping action in the left direction" during active mode M6, "modify heating temperature" is implemented. In the case of fig. 7, the swiping action in the right direction is accepted as increasing the heating temperature, and the swiping action in the left direction is accepted as reducing the heating temperature. Increases and reductions in the heating temperature are implemented in predetermined steps each time a swiping action is detected.
[0104] In the case of this embodiment, modification of the heating temperature means modifying the maximum temperature defined in the heating profile. Incidentally, the maximum amount of aerosol generated also generally increases the higher the maximum temperature.
In the case of fig. 7, the modified temperature is associated with vibration intensity. Accordingly, the intensity of feedback vibration increases the higher the modified temperature, and the intensity of feedback vibration decreases the lower the modified temperature. The modified temperature here is an example of notification content. Moreover, the number of times of vibration is once.
[0105] It should be noted that an example of modifying only the maximum temperature in the heating profile is described in the example of fig. 7, but the left/right direction swiping actions may also be associated with switching the heating profile.
For example, when the control unit 106 handles five types of heating profiles and each heating profile is assigned a management number from "1" to "5", the management number may be updated by the direction of the swiping action For example, one swiping action in the right direction may increase the management number by 1. For example, when the management number before the swiping action is "3", then the management number is changed to "4" by a swiping action in the right direction. Furthermore, one swiping action in the left direction may decrease the management number by 1. For example, when the management number before the swiping action is "3", then the management number is changed to "2" by a swiping action in the left direction.
[0106] Incidentally, when there have been swiping actions in the right direction to the maximum value in the management numbers, then the management number may be changed to the minimum value, or the current management number may be maintained. Similarly, when there have been swiping actions in the left direction to the minimum value in the management numbers, then the management number may be changed to the maximum value, or the current management number may be maintained.
It should be noted that when there has been a left or right swiping action on an aerosol-generating device 1 which is incompatible with the function for modifying temperature, this swiping action is treated as invalid, the operating mode is shifted to error mode M3, error vibration is fed back, or an error sound is fed back. The intensity of error vibration here is an example of second output intensity. The second output intensity is greater than the first output intensity.
• Example 2 (L3-B)
[0107] For example, when there has been a "swiping action in the right direction or the left direction" during active mode M6, "select brand" of stick-type substrate 30 is implemented. In the case of fig. 7, there are three brands of stick-type substrate 30 with which the control unit 106 is compatible, namely "brand A", "brand B", and "brand C".
For example, a swiping action in the right direction may be associated with "change from brand A to brand B" or "change from brand B to brand C", and a swiping action in the left direction may be associated with "change from brand C to brand B" or "change from brand B to brand A".
[0108] The function for changing brand may be limited to cases where heating profiles corresponding to the brand of stick-type substrate 30 are available.
In fig. 7, when the brand following the change is "brand A", vibration of a specific intensity is fed back once, when the brand following the change is "brand B", vibration of a specific intensity is fed back twice, and when the brand following the change is "brand C", vibration of a specific intensity is fed back three times. The specific intensity here is an example of third output intensity. The third output intensity is greater than the first output intensity. Moreover, the third output intensity may have the same magnitude as the second output intensity. The modified brand here is an example of notification content.
[0109] The number of times of feedback vibration varies according to the different brand, so the user can not only confirm that the change of brand has been accepted, but also confirm what the brand is following the change.
It should be noted that when there has been a left or right swiping action on an aerosol-generating device 1 which is incompatible with the function for changing brand, this swiping action is treated as invalid, the operating mode is shifted to error mode M3, error vibration is fed back, or an error sound is fed back. The intensity of error vibration here is an example of second output intensity. The second output intensity is greater than the first output intensity.
<Tapping action (long press)>
[0110] L4, the fourth line from the top of the table, illustrates two commands and the vibration pattern associated with a "tapping action (long press)". In this embodiment, a tap detection time exceeding a threshold is assumed to be a "long pressing action", and a tap detection time not exceeding the threshold is assumed to be a "short pressing action".
[0111] It should be noted that a "tapping action" refers to an action in which the position of a finger detected by the touch sensor 102A is static or largely unchanging, and a "swiping action" refers to an action in which the position of a finger detected by the touch sensor 102A moves or changes. Incidentally, a double tap action or the like may also be used instead of a tapping action (long press).
• Example 1 (L4-A)
[0112] For example, when there has been a "tapping action (long press)" during active mode M6, this is accepted by the control unit 106 as an action to "start heating". In this case, the control unit 106 shifts from active mode M6 to initialization mode M7. It should be noted that the control unit 106 maintains vibration of a given intensity for a given time. The vibration intensity here is an example of second output intensity. Note that the second output intensity is greater than the first output intensity. Here, the completion of acceptance of actions is notified by means of feedback. Accordingly, completion of acceptance of an action is an example of notification content.
[0113] It should be noted that the feedback vibration continues for a fixed period of time, but the output of vibration is started after at least a time equal to or greater than a threshold has elapsed from the completion of acceptance of the tapping action, or is started after the end of the tapping action.
• Example 2 (L4-B)
[0114] For example, when there has been a "tapping action (long press)" during heating mode M8, this is accepted by the control unit 106 as an action to "stop heating". In this case, the control unit 106 shifts from heating mode M8 to heating end mode M9. Again, the control unit 106 maintains vibration of a given intensity for a given time. The vibration intensity here is an example of second output intensity. Note that the second output intensity is greater than the first output intensity. Here, the completion of acceptance of actions is notified by means of feedback. Accordingly, completion of acceptance of an action is an example of notification content.
<Tapping action (short press)>
[0115] L5, the fifth line from the top of the table, illustrates a command and the vibration pattern associated with a "tapping action (short press)".
• Example 1 (L5-A)
[0116] For example, when there has been a "tapping action (short press)" during active mode M6, this is accepted by the control unit 106 as an action to "check remaining battery capacity". In this case, the control unit 106 feeds back a vibration pattern commensurate with the remaining battery capacity acquired from the remaining capacity meter IC. The vibration pattern here stays at a fixed vibration intensity and only the number of times of vibration is different. The vibration intensity here is an example of second vibration intensity. Here, remaining battery capacity is an example of notification content.
[0117] For example, if the remaining battery capacity is 10% or less, no vibration feedback is implemented.
For example, if the remaining battery capacity is greater than 10% and no greater than 60%, vibration is fed back once.
For example, if the remaining battery capacity is greater than 60% and no greater than 90%, vibration is fed back twice.
For example, if the remaining battery capacity is greater than 90%, vibration is fed back three times.
It should be noted that the remaining battery capacity may be fed back by differences in vibration intensity rather than number of times of vibration. For example, if the remaining battery capacity is 10% or less, no vibration feedback is implemented. For example, if the remaining battery capacity is greater than 10% and no greater than 60%, vibration of the first output intensity may be fed back, if the remaining battery capacity is greater than 60% and no greater than 90%, vibration of the second output intensity (>first output intensity) may be fed back, and if the remaining battery capacity is greater than 90%, vibration of the third output intensity (>second output intensity) may be fed back.
<Exemplary Combination 2: Rotational swiping action>
[0119] Unlike Exemplary Combination 1, Exemplary Combination 2 envisages only swiping actions as input actions. However, the swiping actions in Exemplary Combination 2 are substantially circular movements rather than linear movements. An exemplary case is envisaged where the finger is moved clockwise or counterclockwise from the position initially tapped (origin) so as to describe a circle.
[0120] In the case of fig. 8, when movement in an arc shape which is roughly a half-circumference (180°) or greater and a rotation direction have been detected, this is considered to be a rotational swiping action.
[0121] Note that tapping actions may also be included in the input actions, although this is not illustrated in fig. 8.
<Clockwise swiping action>
[0122] L1, the first line from the top of the table, illustrates two commands and the vibration pattern associated with a "clockwise swiping action".
• Example 1 (L1-A)
[0123] For example, when there has been a "clockwise swiping action" during sleep mode M2, the control unit 106 (see fig. 3) changes from a sleep state to an active state. That is to say, the operating mode is shifted from sleep mode M2 to active mode M6. In this case, there is an increase in the intensity of feedback vibration the longer the distance of clockwise movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L1-B)
[0124] For example, when there has been a "clockwise swiping action" during active mode M6, this is accepted by the control unit 106 as an action to "start heating". In this case, the control unit 106 shifts from active mode M6 to initialization mode M7. Again, there is an increase in the intensity of feedback vibration the longer the distance of clockwise movement of the finger. The movement distance here is an example of notification content.
<Counterclockwise swiping action>
[0125] L2, the second line from the top of the table, illustrates two commands and the vibration pattern associated with a "counterclockwise swiping action".
• Example 1 (L2-A)
[0126] For example, when there has been a "counterclockwise swiping action" during active mode M6, the control unit 106 changes from an active state to a sleep state. That is to say, the operating mode is shifted from active mode M6 to sleep mode M2. In this case, there is a reduction in the intensity of feedback vibration the longer the distance of counterclockwise movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L2-B)
[0127] For example, when there has been a "counterclockwise swiping action" during heating mode M8, this is accepted by the control unit 106 as an action to "stop heating". In this case, the control unit 106 shifts from heating mode M8 to heating end mode M9. Again, there is a reduction in the intensity of feedback vibration the longer the distance of counterclockwise movement of the finger. The movement distance here is an example of notification content. It should be noted that the vibration intensity at the start of feedback is an example of second output intensity.
<Clockwise or counterclockwise swiping action>
[0128] L3, the third line from the top of the table, illustrates a command and the vibration pattern associated with a "clockwise swiping action" and a "counterclockwise swiping action". This swiping action corresponds to the "swiping action in both left/right directions" in fig. 7.
• Example 1 (L3-A)
[0129] For example, when there has been a "swiping action in the right direction" or a "swiping action in the left direction" during active mode M6, "modify heating temperature" is implemented. In the case of fig. 8, the control unit 106 accepts a clockwise swiping action as increasing the heating temperature, and accepts a counterclockwise swiping action as reducing the heating temperature. The swiping actions in both rotational directions are indistinguishable on their own from the abovementioned "swiping action in the right direction" and "swiping action in the left direction". When the swiping actions in both rotational directions are used here, they can therefore no longer be used for the activation or sleep described above.
[0130] Again, the intensity of feedback vibration increases the higher the modified temperature, and the intensity of feedback vibration decreases the lower the modified temperature. The modified temperature here is an example of notification content.
<Exemplary Combination 3: Arc swiping action>
[0132] Exemplary Combination 3 also envisages only swiping actions as input actions. However, the swiping actions in Exemplary Combination 3 are substantially arcuate movements rather than linear or substantially circular movements. An exemplary case is envisaged where the finger is moved clockwise or counterclockwise from the position initially tapped (origin) by roughly a half-circumference or roughly a quarter-circumference.
[0133] In the case of fig. 9, when movement in an arc shape which is less than roughly a half-circumference (180°) and a rotation direction have been detected, this is considered to be an arc swiping action.
[0134] Note that tapping actions may also be included in the input actions, although this is not illustrated in fig. 9.
<Lower-semicircular swiping action>
[0135] L1, the first line from the top of the table, illustrates two commands and the vibration pattern associated with a "lower semicircle swiping action". The lower-semicircular swiping action refers to a counterclockwise movement describing roughly a semicircle from the position initially tapped (origin). In this case, the position where the swiping action ends (end point) is at roughly the same height as the origin.
• Example 1 (L1-A)
[0136] For example, when there has been a "counterclockwise semicircular swiping action" during sleep mode M2, the control unit 106 (see fig. 3) changes from a sleep state to an active state. That is to say, the operating mode is shifted from sleep mode M2 to active mode M6. In this case, there is an increase in the intensity of feedback vibration the longer the distance of counterclockwise movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L1-B)
[0137] For example, when there has been a "counterclockwise semicircular swiping action" during active mode M6, this is accepted by the control unit 106 as an action to "start heating". In this case, the control unit 106 shifts from active mode M6 to initialization mode M7. Again, there is an increase in the intensity of feedback vibration the longer the distance of counterclockwise movement of the finger. The movement distance here is an example of notification content.
[0138] It should be noted that both Example 1 and Example 2 describe cases in which a semicircle is described in a counterclockwise direction, but a lower semicircle may equally be described in a clockwise direction.
<Upper-semicircular swiping action>
[0139] L2, the second line from the top of the table, illustrates two commands and the vibration pattern associated with an "upper-semicircular swiping action". The upper-semicircular swiping action refers to a clockwise movement describing roughly a semicircle from the position initially tapped (origin). In this case, the position where the swiping action ends (end point) is at roughly the same height as the origin.
• Example 1 (L2-A)
[0140] For example, when there has been a "clockwise semicircular swiping action" during active mode M6, the control unit 106 changes from an active state to a sleep state. That is to say, the operating mode is shifted from active mode M6 to sleep mode M2. In this case, there is a reduction in the intensity of feedback vibration the longer the distance of clockwise movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L2-B)
[0141] For example, when there has been a "clockwise semicircular swiping action" during heating mode M8, this is accepted by the control unit 106 as an action to "stop heating". In this case, the control unit 106 shifts from heating mode M8 to heating end mode M9. Again, there is a reduction in the intensity of feedback vibration the longer the distance of clockwise movement of the finger. The movement distance here is an example of notification content. It should be noted that the vibration intensity at the start of feedback is an example of second output intensity.
[0142] It should be noted that both Example 1 and Example 2 describe cases in which a semicircle is described in a clockwise direction, but an upper semicircle may equally be described in a counterclockwise direction.
<Clockwise or counterclockwise quarter-circle arc swiping action>
[0143] L3, the third line from the top of the table, illustrates a command and the vibration pattern associated with a "clockwise swiping action describing a quarter-circle arc" and a "counterclockwise swiping action describing a quarter-circle arc". This swiping action also corresponds to the "swiping action in both left/right directions" in fig. 7.
• Example 1 (L3-A)
[0144] For example, when there has been a "counterclockwise swiping action describing a quarter-circle arc" or a "clockwise swiping action describing a quarter-circle arc" during active mode M6, "modify heating temperature" is implemented. In the case of fig. 9, the counterclockwise swiping action describing a quarter-circle arc is accepted as increasing the heating temperature, and the clockwise swiping action describing a quarter-circle arc is accepted as reducing the heating temperature.
[0145] Again, the intensity of feedback vibration increases the higher the modified temperature, and the intensity of feedback vibration decreases the lower the modified temperature. The modified temperature here is an example of notification content.
<Exemplary Combination 4: Other swiping actions>
[0146] Fig. 10 is a table illustrating Exemplary Combination 4 of input actions and haptic feedback. Exemplary Combination 4 also envisages only swiping actions as input actions. However, the swiping actions in Exemplary Combination 4 envisage linear movements to draw characters, figures and other patterns with a single stroke.
[0147] Note that tapping actions may also be included in the input actions, although this is not illustrated in fig. 10.
<Z-shaped swiping action>
[0148] L1, the first line from the top of the table, illustrates two commands and the vibration pattern associated with a "Z-shaped swiping action". The Z-shaped swiping action is effective for ensuring the distance of finger movement within limited dimensions. Moreover, other possible characters also include: include "C", "J", "L", "M", "N", "S", "U", "V", "W", "2", "3", "6", "7", "8" and "9", etc.
• Example 1 (L1-A)
[0149] For example, when there has been a "Z-shaped swiping action" during sleep mode M2, the control unit 106 (see fig. 3) changes from a sleep state to an active state. That is to say, the operating mode is shifted from sleep mode M2 to active mode M6. In this case, there is an increase in the intensity of feedback vibration the longer the distance of movement of the finger drawing the Z shape. The movement distance here is an example of notification content.
• Example 2 (L1-B)
[0150] For example, when there has been a "Z-shaped swiping action" during active mode M6, this is accepted by the control unit 106 as an action to "start heating". In this case, the control unit 106 shifts from active mode M6 to initialization mode M7. Again, there is an increase in the intensity of feedback vibration the longer the distance of movement of the finger drawing the Z shape. The movement distance here is an example of notification content.
<Downward swiping action>
[0151] L2, the second line from the top of the table, illustrates two commands and the vibration pattern associated with a "downward swiping action".
• Example 1 (L2-A)
[0152] For example, when there has been a "downward swiping action" during active mode M6, the control unit 106 changes from an active state to a sleep state. That is to say, the operating mode is shifted from active mode M6 to sleep mode M2. In this case, there is a reduction in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L2-B)
[0153] For example, when there has been a "downward swiping action" during heating mode M8, this is accepted by the control unit 106 as an action to "stop heating". In this case, the control unit 106 shifts from heating mode M8 to heating end mode M9. Again, there is a reduction in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is an example of notification content. It should be noted that the vibration intensity at the start of feedback is an example of second output intensity.
<Diagonal swiping actions>
[0154] L3, the third line from the top of the table, illustrates two commands and the vibration pattern associated with a "swiping action diagonally up to the right" and a "swiping action diagonally down to the left".
• Example 1 (L3-A)
[0155] For example, when there has been a "swiping action diagonally up to the right" or a "swiping action diagonally down to the left" during active mode M6, "modify heating temperature" is implemented. In the case of fig. 10, the swiping action diagonally up to the right is accepted as increasing the heating temperature, and the swiping action diagonally down to the left is accepted as reducing the heating temperature.
[0156] In the case of fig. 10 also, the modified temperature is associated with vibration intensity. Accordingly, the intensity of feedback vibration increases the higher the modified temperature, and the intensity of feedback vibration decreases the lower the modified temperature. The modified temperature here is an example of notification content.
<Other feedback>
[0157] The examples of actions described above envisage feedback during input actions and feedback with respect to the results of actions, but feedback for other purposes will be described here.
[0160] The first notification is a notification of "detect start of action". The first notification is effective when there is a time difference between the timing of inputting an action and the corresponding output of vibration feedback, as is the case with "modify heating temperature", "select brand", and "check remaining battery capacity", for example.
[0161] When the position of the touch sensor 102A is unclear, the user may feel unsure that their action is being detected.
However, if there is vibration feedback at the time when the start of an action was detected due to a finger touching a predetermined position, for instance, the user can continue to input the action with confidence.
[0162] Note that the vibration intensity used to notify "detect start of action" is ST1. The vibration intensity ST1 is intended only for notifying detection and should therefore be lower than the vibration intensity used for other feedback. The vibration motor 103A serving as the vibration source is at a short distance from the fingertip, so vibration feedback can be transmitted to the user even with a low vibration intensity.
The vibration intensity ST1 here is an example of first output intensity. Furthermore, the output pattern corresponding to this vibration intensity ST1 is an example of a first output pattern. Incidentally, the first notification may be combined with input of other actions described above.
[0163] The second notification is a notification of "acceptance of action complete".
The descriptions above assumed that the user's finger movements and times of actions were correctly recognized as the input actions illustrated, but in actual fact there may also be cases where the user's finger movements and times of actions are not recognized as the input actions described above. For example, if the distance of movement of the finger is extremely short, or if the time of a tap is extremely short, the finger movement may be indistinguishable from input of other actions.
[0164] In such cases, the user's perception may not match the actual operation. For example, it could happen that heating is not started, heating is not stopped, or the heating temperature is not modified.
[0165] The second notification therefore provides a function of giving vibration feedback to notify "acceptance of action complete". The vibration intensity used for this notification is ST2. As shown in fig. 11, the vibration intensity ST2 is greater than the vibration intensity ST1 and is distinguishable from the vibration intensity ST1. Note that the vibration intensity ST2 is an example of second output intensity.
The feedback with the vibration intensity ST2 is output at the time when acceptance of the action has been completed. A user who has perceived the vibration intensity ST2 can therefore be made aware that, even though their action is unfinished, the action has been accepted as a specific input action. As a result, the user can stop the input action without any hesitation. In the absence of this notification, the user would need to continue inputting the action without being sure.
<Advantageous Effects>
[0166] Using the aerosol-generating device 1 (see fig. 1) according to this embodiment enables the mode of output from the vibration motor 103A (e.g., absence or presence of vibration, vibration intensity, number of times of vibration) to be switched according to the input action. In other words, the aerosol-generating device 1 is capable of switching the mode of output from the vibration motor 103A in accordance with the content notified to the user. By switching the mode of output, the user can be given an actual appreciation of acceptance of input actions or corresponding information, even without any mechanical displacement accompanying input of the action.
[0167] Furthermore, the aerosol-generating device 1 according to this embodiment is provided with a function for feeding back detection of the start of an action by vibration of a first output intensity, therefore enabling the user to perceive that contact with the main body portion 10 has been detected as the start of an action.
[0168] Incidentally, no vibration feedback is given if the user touches a place where the touch sensor 102A is not provided. The presence of vibration feedback can therefore make the user aware that user contact has been detected as the start of an action.
The presence of vibration feedback when there has been unintentional contact with the main body portion 10 can furthermore make the user realize that their unintentional action has been detected as an input action.
[0169] It should be noted that the first output intensity is smaller than the second output intensity of vibration feedback which is used during actions. It is therefore also possible that the user will not be aware of vibration feedback of the first output intensity. In that case, however, the user can be made aware that their finger movement is being detected as input of an action by the vibration feedback linked to the action.
[0170] Furthermore, the aerosol-generating device 1 according to this embodiment is provided with a function for feeding back completion of acceptance of an action, by vibration of the second output intensity (>first output intensity). The user can therefore be made aware that their input action is complete. As a result, the user has no need to continue an unnecessary input action while remaining unaware that the action has been completed.
It should be noted that the intensity of vibration used to notify completion of acceptance of an action (second vibration intensity) is greater than the intensity of vibration used to notify detection of the start of an action (first vibration intensity), so the user can notice the difference in the two vibrations.
[0171] Incidentally, in the case of switching-related actions (e.g., modifying the heating temperature, modifying brand of stick-type substrate 30) and checking-related actions (e.g., checking the remaining battery capacity), the result of the switch and information on the remaining battery capacity are fed back by vibration after a given period of time (e.g., 2 seconds) has elapsed from notification of completion of acceptance of the action. This ensures that the user does not confuse the two notifications.
<Embodiment 2>
[0172] Another example of the contact sensor will be described in this embodiment. Accordingly, the external appearance and other components and functions are the same as those of Embodiment 1, except for the parts associated with the contact sensor.
[0174] Fig. 12 is a diagram to illustrate the positional relationship of the nine touch sensors 102A and the vibration motor 103 in Embodiment 2. Corresponding reference signs are given in fig. 12 for parts that correspond to those of fig. 4.
This embodiment differs from Embodiment 1 in that the nine substantially circular touch sensors 102A are arranged in 3 rows × 3 columns. Incidentally, the placement of the vibration motor 103A is roughly the same as in Embodiment 1.
[0175] The nine touch sensors 102A are arranged on the rear face side of the housing on the front face side, and the vibration motor 103A is arranged inwardly from the nine touch sensors 102A. In the case of this embodiment, each of the nine touch sensors 102A detects finger contact. Finger contact will therefore not be detected if the finger touches the gap areas between the nine touch sensors 102A. In the case of this embodiment, tapping actions are therefore carried out by detecting contact on any one of the nine touch sensors 102A. Furthermore, input actions involving a pattern are detected as a pattern which is formed by joining, in succession, coordinate positions of the touch sensors 102A which have detected finger contact.
[0176] Fig. 13 is a diagram to illustrate the relationship of touch sensor 102A arrangement and input actions in Embodiment 2.
In fig. 13, the positions of the touch sensors 102A located in the first row from the top are represented by P1n (n=1,2,3), the positions of the touch sensors 102A located in the second row from the top are represented by P2n (n=1,2,3), and the positions of the touch sensors 102A located in the third row from the top are represented by P3n (n=1,2,3).
Note that n=1 means the left hand end, n=2 means the middle, and n=3 means the right hand end.
[0177] For example, an upward swiping action is detected when finger contact in the order of P31→P21→P11 has been detected. The same also applies when finger contact has been detected in the order of P32→P22→P12, and when finger contact has been detected in the order of P33→P23→P13.
Meanwhile, a downward swiping action is detected when finger contact has been detected in the order of P11→P21→P31. The same also applies when finger contact has been detected in the order of P12→P22→P32, and when finger contact has been detected in the order of P13→P23→P33.
In other words, when finger contact has been detected in the order of arrangement of three touch sensors 102A positioned in the same column, this is judged to be an upward swiping action or a downward swiping action.
[0178] Similarly, when finger contact has been detected in the order of arrangement of three touch sensors 102A positioned in the same row, this is judged to be a right swiping action or a left swiping action.
Incidentally, when finger contact has been detected in the order of P31→P22→P13, or when finger contact has been detected in the order of P33→P22→P11, this is detected as a diagonally upward swiping action.
Furthermore, when finger contact has been detected in the order of P11→P22→P33, or when finger contact has been detected in the order of P13→P22→P31, this is detected as a diagonally downward swiping action.
<Other Example 1>
[0179] In the case of the description above, all nine touch sensors 102A are constantly operative, but only three of the touch sensors 102A positioned in the second row may be operative during sleep mode M2. That is to say, only the second row may be enabled as an input region, and the first and third rows may be disabled regions. In this case, power can be saved because only three of the touch sensors 102A are operative.
[0180] Fig. 14 is a diagram to illustrate the enabled region and the disabled regions for input actions during sleep mode M2. Corresponding reference signs are given in fig. 14 for parts that correspond to those of fig. 12.
[0181] In fig. 14, the touch sensors 102A in the first and third rows corresponding to the disabled regions are represented by shading.
Incidentally, only the three touch sensors 102A positioned in the second row are enabled, so a tapping action, a swiping action in the right direction, or a swiping action in the left direction is assigned to the input action for activation.
<Other Example 2>
[0182] In the description given above, a case where three touch sensors 102A arranged in a line have detected finger contact in succession is considered as an input action, but the action may be deemed an input action at the stage where two touch sensors 102A arranged in a line have detected finger contact in succession. For example, when finger contact has been detected in the order of P31→P21, or when finger contact has been detected in the order of P21→P11, this may be considered as an upward swiping action. The same also applies to other input actions.
<Other Example 3>
[0183] In the description given above, a case where three touch sensors 102A arranged in a line have detected finger contact in succession is considered as an input action, but the action may be deemed an input action as long as three touch sensors 102A across three rows detect finger contact. For example, when finger contact has been detected in the order of P31→P21→P12, this may also be considered as an upward swiping action. The same also applies to other input actions.
<Other Example 4>
[0184] In the description given above, a case was described where the nine touch sensors 102A are arranged in 3 rows/3 columns, but the number and arrangement of touch sensors 102A may be varied so that they are arranged in 2 rows/2 columns, 4 rows/4 columns, 2 rows/3 columns, or 3 rows/4 columns, etc.
<Embodiment 3>
[0185] Another exemplary arrangement of the contact sensor will be described in this embodiment. Accordingly, the external appearance and other components and functions are the same as those of Embodiment 1, except for the parts associated with the arrangement of the contact sensor.
[0186] In the case of this embodiment, the contact sensor is provided in a region of the main body portion 10 (see fig. 1) extending from the upper face across the side face.
[0187] Fig. 15 is a diagram to illustrate the positional relationship of the touch sensor 102A and the vibration motor 103A in Embodiment 3. Corresponding reference signs are given in fig. 15 for parts that correspond to those of fig. 1.
[0188] In the case of fig. 15, the touch sensor 102A is arranged so as to extend from the right hand side of the upper face across the right side face, facing toward the front face of the main body portion 10. This arrangement assumes that the face on the opposite side to the front face (i.e., the back face) of the main body portion 10 is gripped with the right hand, and actions are performed with the right thumb.
[0189] The two faces across which the touch sensor 102A extends are not limited to the upper face and the right side face, and may be any faces such as the upper face and the left side face, the upper face and the front face, or the upper face and the back face, for example.
[0190] This embodiment envisages two types of swiping actions and one type of tapping action on the touch sensor 102A.
[0191] Fig. 16 is a diagram to illustrate an example of a downward swiping action. Corresponding reference signs are given in fig. 16 for parts that correspond to those of fig. 15.
[0192] The arrow in the drawing represents the downward swiping action. In the case of fig. 16, the downward swiping action assumes a swiping action extending from the upper face across the right side face.
[0193] Fig. 17 is a diagram to illustrate an example of an upward swiping action. Corresponding reference signs are given in fig. 17 for parts that correspond to those of fig. 15.
The arrow in the drawing represents the upward swiping action. In the case of fig. 17, the upward swiping action assumes a swiping action extending from the right side face across the upper face.
Fig. 18 is a table illustrating exemplary combinations of input actions and haptic feedback in Embodiment 3.
As described above, this embodiment envisages a downward swiping action, an upward swiping action, and a tapping action as input actions.
<Downward swiping action>
[0194] L1, the first line from the top of the table, illustrates two commands and the vibration pattern associated with a "downward swiping action".
• Example 1 (L1-A)
[0195] For example, when there has been a "downward swiping action" during sleep mode M2, the control unit 106 (see fig. 3) changes from a sleep state to an active state. That is to say, the operating mode is shifted from sleep mode M2 to active mode M6. In this case, there is an increase in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is an example of notification content.
• Example 2 (L1-B)
[0196] For example, when there has been a "downward swiping action" during active mode M6, this is accepted by the control unit 106 as an action to "start heating". In this case, the control unit 106 shifts from active mode M6 to initialization mode M7. Again, there is an increase in the intensity of feedback vibration the longer the distance of downward movement of the finger. The movement distance here is an example of notification content.
<Upward swiping action>
[0197] L2, the second line from the top of the table, illustrates two commands and the vibration pattern associated with an "upward swiping action".
• Example 1 (L2-A)
[0198] For example, when there has been an "upward swiping action" during active mode M6, the control unit 106 changes from an active state to a sleep state. That is to say, the operating mode is shifted from active mode M6 to sleep mode M2. In this case, there is a reduction in the intensity of feedback vibration the longer the distance of upward movement of the finger. The movement distance here is also an example of notification content.
• Example 2 (L2-B)
[0199] For example, when there has been an "upward swiping action" during heating mode M8, this is accepted by the control unit 106 as an action to "stop heating". In this case, the control unit 106 shifts from heating mode M8 to heating end mode M9. Again, there is a reduction in the intensity of feedback vibration the longer the distance of upward movement of the finger. The movement distance here is also an example of notification content. It should be noted that the vibration intensity at the start of feedback is an example of second output intensity.
<Tapping action>
[0200] L3, the third line from the top of the table, illustrates a command and the vibration pattern associated with a "tapping action (short press)".
• Example 1 (L3-A)
[0201] For example, when there has been a "tapping action (short press)" during active mode M6, this is accepted by the control unit 106 as an action to "check remaining battery capacity". In this case, the control unit 106 feeds back a vibration pattern commensurate with the remaining battery capacity acquired from the remaining capacity meter IC. The remaining battery capacity here is an example of notification content.
<Other configurations>
[0202] Fig. 19 is a diagram to illustrate another positional relationship of the touch sensor 102A and the vibration motor 103A in Embodiment 3. Corresponding reference signs are given in fig. 19 for parts that correspond to those of fig. 15.
[0203] In the case of the aerosol-generating device 1 shown in fig. 19, the touch sensor 102A is provided on an upper portion of the right side face, facing toward the front face. This arrangement also envisages actions with the thumb of the right hand holding the main body portion 10. Furthermore, the aerosol-generating device 1 shown in fig. 19 also envisages upward/downward swiping actions and tapping actions.
<Embodiment 4>
[0204] This embodiment describes another example of the external appearance of the aerosol-generating device 1.
[0205] However, the other components and functions are the same as those of Embodiment 1, except for the arrangement of the contact sensor and haptic device associated with the different external appearance.
[0206] Fig. 20 is a diagram in which the aerosol-generating device 1 envisaged by Embodiment 4 is seen from diagonally above. Corresponding reference signs are given in fig. 20 for parts that correspond to those of fig. 1.
[0207] The external appearance of the aerosol-generating device 1 envisaged by this embodiment is substantially cylindrical, and the opening 10A into which the stick-type substrate 30 (see fig. 3) is inserted is disposed in the upper face. In the case of fig. 20, there is no slide cover 20 (see fig. 1) provided to open/close the opening 10A.
[0208] In the case of fig. 20, the touch sensor 102A is arranged over the whole circumference on the housing rear side on the upper portion side of the main body portion 10. This embodiment allows the user to grip the main body portion 10 without having to think about orientation, and allows input actions with the thumb. Incidentally, the heating unit 107 (see fig. 3) and the heat insulating portion 108 (see fig. 3), neither of which is depicted here, are arranged on the outer periphery of the internal space 109A, and the touch sensor 102A is positioned on the outer side thereof.
[0209] In the case of fig. 20, the vibration motor 103A is arranged in a central region of the main body portion 10. This is because there is limited space on the upper portion side of the main body portion 10 for arranging the vibration motor 103A. The vibration motor 103A may be arranged in any location as long as the user can perceive differences in vibration intensity.
The aerosol-generating device 1 shown in fig. 20 enables input actions afforded by up/down/left/right swiping actions and tapping actions, similarly to Embodiment 1. Moreover, diagonally upward and diagonally downward swiping actions may also be used as input actions.
<Other configurations>
[0210] Fig. 21 is a diagram to illustrate another positional relationship of the touch sensor 102A and the vibration motor 103A in Embodiment 4. Corresponding reference signs are given in fig. 21 for parts that correspond to those of fig. 20.
[0211] In the case of the aerosol-generating device 1 shown in fig. 21, the touch sensor 102A is provided so as to extend from the upper face of the main body portion 10 across the side face. Note that the touch sensor 102A is confined to a partial arc section rather than the whole circumference of the main body portion 10. This arrangement also envisages actions with the thumb of the right hand holding the main body portion 10. Furthermore, the aerosol-generating device 1 shown in fig. 21 also envisages upward/downward swiping actions and tapping actions.
<Embodiment 5>
[0212] Fig. 22 is a diagram in which the aerosol-generating device 1 envisaged by Embodiment 5 is seen from diagonally above. Corresponding reference signs are given in fig. 22 for parts which correspond to those of fig. 1 and 15.
[0213] As shown in fig. 22, two touch sensors 102A1 and 102A2 are provided in the aerosol-generating device 1 envisaged by Embodiment 5.
[0214] In the case of fig. 22, the touch sensor 102A1 is provided on the front face of the main body portion 10, and the touch sensor 102A2 is provided extending from the upper face across the right side face of the main body portion 10. This arrangement corresponds to a combination of Embodiment 1 and Embodiment 3.
[0215] When the two touch sensors 102A1 and 102A2 are provided in this way, one instruction may be assigned to both of the two touch sensors 102A, or one instruction may be assigned to only either one of the touch sensors 102A.
For example, activation and sleeping may be assigned to the touch sensor 102A2 arranged so as to extend from the upper face of the main body portion 10 across the right side face, and sending and receiving of heating profiles may be assigned to the touch sensor 102A1 arranged on the front face of the main body portion 10.
[0216] Note that the vibration motor 103A is arranged in an intermediate area between the two touch sensors 102A1 and 102A2, for example. In the case of fig. 22, the vibration motor 103A is arranged close to the right corner of the front face of the main body portion 10. When either the touch sensor 102A1 or the touch sensor 102A2 is used for input actions, vibration feedback during the action can therefore be easily transmitted to the user.
When the two touch sensors 102A1 and 102A2 are provided, more than one input action can be assigned to one operating mode. For example, during active mode M6, start heating may be assigned to an upward swiping action on the touch sensor 102A1, and send heating profile may be assigned to an upward swiping action on the touch sensor 102A2.
<Embodiment 6>
[0217] Fig. 23 is a diagram to illustrate the relationship of mounting positions of the touch sensors 102A1 and 102A2, and the vibration motor 103A in Embodiment 6. Corresponding reference signs are given in fig. 23 for parts that correspond to those of fig. 5.
[0218] Similarly to fig. 5, fig. 23 is also seen through the inside of the main body portion 10 from the right face side. That is to say, fig. 23 shows the positional relationship of the touch sensors 102A1 and 102A2, and the vibration motor 103A arranged in the main body portion 10, as seen therethrough.
[0219] As shown in fig. 23, two touch sensors 102A1 and 102A2 are provided in the aerosol-generating device 1 envisaged by Embodiment 6. One touch sensor 102A1 is provided on the front face of the main body portion 10, and the other touch sensor 102A2 is provided on the rear face of the main body portion 10.
[0221] When the touch sensor 102A1 and the touch sensor 102A2 are arranged on both faces of the main body portion 10, the control unit 106 disables input on the face having a large contact area with the fingers or the palm of the hand, and controls the face on the opposite side (i.e., the face on the side that the thumb touches) to be the input face.
[0222] In this case, whether the user is holding the device with the rear face in contact with the right thumb, or with the rear face in contact with the left thumb, in either case the user can start an input action without changing grip.
<Other embodiments>
[0223]
- (1) Embodiments of the present disclosure were described above, but the technical scope of the present disclosure is not limited to the scope disclosed in the embodiments above. It will be obvious from the disclosure of the claims that the technical scope of the present disclosure also includes various modifications or improvements made to the embodiment above.
- (2) An LRA was given by way of example as the vibration motor in the embodiments described above, but the vibration motor may equally be an ERM (= eccentric rotating mass). An ERM has a structure in which a weight with a biased shape is attached to a rotary shaft of a motor, and is also referred to as an eccentric motor. An ERM having a weight with a larger mass can generate larger vibrations than a weight with a smaller mass. Furthermore, an ERM with a greater rotation speed of the rotary shaft can generate larger vibrations than with a lower rotation speed.
- (3) In the embodiments described above, a vibration motor was given by way of example as a haptic device, but a piezoelectric element may equally be used. A piezoelectric element can freely control vibration at 50-500 Hz, at which changes in touch are perceived. Furthermore, piezoelectric elements have a response time of approximately 1 ms, which is shorter than an LRA.
- (4) In the embodiments described above, vibration was given as an example of haptic feedback, but electrostatic haptics employing electrostatic force may equally be used. Note that examples of electrostatic haptics include electrical stimulation and electrostatic attraction. Electrical stimulation can be demonstrated by a haptic device constructed with an electrode to which a high voltage is applied and an electrode connected to GND. Electrostatic attraction can be demonstrated by a haptic device comprising an electrode which is charged by application of a voltage, an electrode connected to GND, and an insulator disposed between these two electrodes.
- (5) In the embodiments described above, the single control unit 106 controls the two functions of heating of the stick-type substrate 30 (see fig. 3) by the heating unit 107 and haptic feedback, but a dedicated processor for controlling heating of the stick-type substrate 30 (see fig. 3) by the heating unit 107, and a dedicated processor for controlling output of the haptic device may equally be provided. The dedicated processor for controlling heating here is an example of a first processor, and the dedicated processor for controlling output of the haptic device is an example of a second processor.
- (6) In the embodiments described above, tapping actions and swiping actions were given as examples of input actions, but some of these actions may be substituted with flicking actions, or flicking actions may be combined with these actions.
- (7) The embodiments above described a case in which the aerosol source is a solid, but the aerosol source may equally be a liquid. When the aerosol source is a liquid, a system is adopted in which the aerosol source is guided to a narrow tube known as a wick by using the capillary phenomenon, and a coil wound around the wick is heated to thereby vaporize the aerosol source. It should be noted that if the aerosol source is a liquid, the aerosol source is heated in conjunction with inhalation by the user. A container for accommodating the liquid aerosol source is also referred to as a cartridge.
- (8) The embodiments above described an aerosol-generating device which generates an aerosol by heating a solid aerosol source, but the aerosol-generating device may equally generate an aerosol by separately heating each of a solid aerosol source and a liquid aerosol source. An aerosol-generating device of this type is also referred to as a hybrid aerosol-generating device.
- (9) There are input actions specific to an aerosol-generating device 1 which heats a solid aerosol source at a high temperature (e.g., 200°C or greater), and there are input actions specific to an aerosol-generating device 1 which heats a solid aerosol source at a low temperature (e.g., less than 200°C) or heats a liquid aerosol source, and there are also input actions common to both systems.
[0224] Fig. 24 is a table illustrating differences in input actions in aerosol-generating devices due to differences in types of aerosol source and heating temperatures.
[0225] In fig. 24, the input actions are classified according to combinations of four types of input actions, two types of aerosol sources, and three types of heating systems.
The four types of input actions relate to "basic operation", "switching", "communication", and "checking".
The two types of aerosol sources are a solid aerosol source and a liquid aerosol source. Note that the solid aerosol source can be classified as a high-temperature-heating aerosol source and a low-temperature-heating aerosol source.
[0226] The three types of heating systems are a system for heating a solid aerosol source at a high temperature, a system for heating a solid aerosol source at a low temperature, and a system for heating a liquid aerosol source.
The input actions shown in fig. 24 are associated with the abovementioned tapping actions and swiping actions, etc. and a different vibration pattern is associated with each input action. For example, vibration patterns (e.g., number of times of vibration, vibration intensity, vibration timing) representing: information to be notified (e.g., brand, heating profile, heating temperature, detection sensitivity, display mode, charging status); quantity (e.g., remaining battery capacity (lifespan), remaining inhalation time, remaining amount of liquid, remaining amount in capsule); or number (e.g., number of inhalations, remaining number of inhalations, remaining number of times of inhalation, cumulative number of times of inhalation), are assigned to switching- or checking-related input actions.
[0227] This makes it possible to realize an aerosol-generating device 1 in which a contact device and haptic feedback are used on a user interface.
