SMART WEARABLE APPARATUS, SMART WEARABLE DEVICE, AND CONTROL METHOD

Description

TECHNICAL FIELD

[0001] The present invention relates to human-computer interaction, and more particularly, to smart wearable apparatus for providing the sense of gripping and holding a virtual object in a virtual scene.

BACKGROUND

[0002] Virtual reality (VR) technology and augmented reality (AR) technology are important areas relating to simulation technology. People feel the same when experiencing VR technology and AR technology as they do in the real world because VR and AR produce the same feedback information to the brain and sensory receptors as that produced in the real world. With the rapid development of the many technologies associated with VR, including display technology, graphics and image processing technology, multimedia technology, tracking technology, parallel processing technology, the application of VR technology has gradually expanded and is now employed in many fields.

[0003] In the field of human-computer interaction technology such as VR and AR, if an otherwise tangible object such as a water cup or a flower, for example, exists in a virtual scene, a challenge now presented to skilled innovators is how to make users feel, although in VR and AR, as if they are gripping or holding the object in the real world.

[0004] Currently, in an implementation mode, those skilled in the game art, for example, have invented devices enabling the hand to sense an object in virtual reality. The device, such as a glove, is provided with a plurality of moveable concave and convex points on its palm surface. When simulating the object in a virtual scene, the device can adjust the concave and convex points according to the game to reflect back to the user the corresponding tactile sense in real time. In addition, after adjustment, the concave and convex points can simulate the sense of touching the hard/soft object, so as to simulate the sense of touching the object in the real world.

[0005] In another implementation mode, those skilled in the art have invented a controller that can be held in the hand. The controller is provided with a plurality of sensors to capture the relevant actions of the hand. When the user wants to grip the object in the virtual scene, the user can grip the controller by hand in the real scene. Alternatively, the user can grab, hold, release the controller to grab, hold, release the virtual object in the virtual scene.

[0006] For the implementation modes described above, however, the user can only experience the sense of contiguousness, or is required to grip a controller having a single size, which may not be at all consistent with the object. Therefore, current sensory creating and feedback devices and methods have limited utility in simulating sensory perception of gripping objects with different sizes in the virtual scene, and the user does not feel and hence respond to the feedback in the same manner as he/she would in the real world. The experience, therefore, has an artificial feel. WO2016107679 discloses haptic devices and corresponding control methods.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely below in combination with the drawings in the embodiments of the present invention.

[0020] Obviously, the described embodiments are only examples of embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort shall fall within the scope of protection of the present invention.

Embodiment 1

[0021] The embodiment of the present invention provides a smart wearable apparatus. FIG. 1 shows the front view of the smart wearable apparatus 100, and FIG. 2 shows a side view of the smart wearable apparatus 100 along another angle.

[0022] As shown in FIGS. 1 and 2, the smart wearable apparatus 100 is a VR (virtual reality) glove matched with a VR apparatus, or an AR (augmented reality) glove with an AR apparatus, which includes the rigid body 10, at least one hinge mechanism 20, the brake 30, and the controller 40.

[0023] In an optional embodiment, the smart wearable apparatus 100 may further include a wearable portion (not shown in the figures), such as a soft glove, a soft or rigid band, a strap and others, and the wearable portion is fixedly connected to the palm of the user. In an optional embodiment, the smart wearable apparatus may further include a power supply device (not shown in the figures) for providing power.

[0024] In the present embodiment, the rigid body 10 may be matched with the palm of the user in shape, which includes a finger portion and a palm portion. The rigid body 10 is provided with the hinge mechanism 20. For example, a plurality of hinge mechanisms 20 may be arranged at positions corresponding to the positions of the joints of hand of the user, respectively. According to the connection relationship between the hinge mechanism 20 and the rigid body 10 shown at the upper left of FIG. 1, the rigid body 10 is divided by the hinge structure 20 into the first portion 11 and the second portion 12.

[0025] As shown in FIG. 2, the hinge mechanism 20 includes the first pivot portion 21, the second pivot portion 22, and the pivot 23 arranged between the first pivot portion 21 and the second pivot portion 22. By means of the hinge mechanism 20, the first portion 11 of the rigid body 10 connected to the first pivot portion 21 of the hinge mechanism 20 and the second portion 12 of the rigid body 10 connected to the second pivot portion 22 of the hinge mechanism 20 can pivot relative to each other in a first direction. The first direction is, for example, the same as the direction in which the joints of hand of the user bends.

[0026] The brake 30 is connected to the hinge mechanism 20, and the brake 30 can receive a first control signal from the controller to stop the hinge mechanism 20, thereby stopping the first portion 11 and the second portion 12 of the rigid body 10 from relatively pivoting.

[0027] The controller 40 may be arranged on the rigid body 10 as shown in FIG. 1 or on other positions of the smart wearable apparatus.

[0028] In an optional embodiment, as shown in FIG. 1, the smart wearable apparatus 100 includes a plurality of hinge mechanisms 20, and a plurality of brakes 30 for respectively stopping the plurality of hinge mechanisms 20. Each of the plurality of hinge mechanisms 20 is connected to two portions of the rigid body 10, so that the two portions can pivot by the hinge mechanism 20.

[0029] In an optional embodiment, the plurality of hinge mechanisms 20 and the plurality of brakes 30 are arranged at positions corresponding to the positions of the joints of hand of the user, so that the smart wearable apparatus better fits contours of the hand of the user to provide a more realistic feeling.

[0030] According to the invention, the first portion 11 and the second portion 12 of the rigid body 10 connected to the hinge mechanism 20 pivot relative to each other in a second direction opposite to the first direction. The brake 30 stops the pivoting in the first direction and allow the pivoting in the second direction opposite to the first direction.

[0031] The brake 30 is a clutch. As shown in FIG. 3, the clutch includes the clutch outer ring 31, the clutch inner ring 32, and the blocking member 33.

[0032] One of the clutch outer ring 31 and the clutch inner ring 32 is connected to the first pivot portion 21 of the hinge mechanism 20, and the other one of the clutch outer ring 31 and the clutch inner ring 32 is connected to the second pivot portion 22 of the hinge mechanism 20. The blocking member 33 can extend between the clutch outer ring 31 and the clutch inner ring 32 to limit the relative rotations of the clutch outer ring 31 and the clutch inner ring 32, thereby limiting the relative motions of the first portion 11 and the second portion 12 of the rigid body 10.

[0033] According to the invention, The clutch is an overrunning clutch, and the inner ring 32 of the overrunning clutch includes the groove 32a provided along the axial direction of the overrunning clutch, the blocking member 33 and the spring 34, wherein the blocking member 33 and the spring 34 are arranged in the groove 32a. From the cross-sectional direction shown in FIG. 3, the groove 32a has a larger cross section at one end and a smaller cross section at the other end. The cross section at the end of the groove 32a adjacent to the spring 34 is larger than the cross section at the other opposite end. The cross section of the groove 32a may be in a fan shape as shown in FIG.3, or other shapes such as triangles, cones, and others, which are not limited by the present invention.

[0034] The blocking member 33 extends into the groove 32a and may be a cylinder capable of extending into the groove 32a. The spring 34 Presses against the blocking member 33 to provide a force to limit the relative rotations of the clutch outer ring 31 and the clutch inner ring 32.

[0035] In general, the blocking member 33 of the overrunning clutch does not extend into the groove 32a, so the outer ring 31 and the inner ring 32 move without interference with each other. Accordingly, the first pivot portion 21 and the second pivot portion 22 of the hinge mechanism 20 which are respectively connected to the inner ring 32 and the outer ring 31 move without interference with each other, and the first portion 11 and the second portion 12 of the rigid body 10 also move without interference with each other. When it is required to stop the hinge mechanism, however, the power supply device can provide power to drive the blocking member 33 to extend into the groove 32a of the clutch inner ring 32, and the spring 34 presses against the blocking member 33, so that the clutch outer ring 31 cannot move in the first direction M relative to the clutch inner ring 32. Accordingly, the first pivot portion 21 and the second pivot portion 22 of the hinge mechanism 20 cannot move toward the first direction M, and the first portion 11 and the second portion 12 of the rigid body 10 cannot move toward the first direction M.

[0036] For example, the clutch inner ring 32 is connected to the first pivot portion 21 of the hinge mechanism 20 and is indirectly connected to the first portion 11 of the rigid body 10, and the clutch outer ring 31 is connected to the second pivot portion 22 of the hinge mechanism 20 and is indirectly connected to the second portion 12 of the rigid body 10. In normal operation, when the user wants to hold an object in the virtual scene, the second portion 12 of the rigid body 10 does not move, and the first portion 11 pivots toward the second portion 12. However, when the boundary of the object in the virtual scene coincides with the position of the hand of the user, the user can no longer hold the object, so the controller 40 issues an instruction, and then the power supply device drives the blocking member 33 to insert between the clutch outer ring 31 and the clutch inner ring 32, so that the clutch outer ring can no longer move in the first rotation direction M relative to the clutch inner ring 32. When the user feels that he/she cannot continue to clench his/her hand, the controller concludes that he/she has gripped the object in the virtual scene.

[0037] However, when the user wishes to loosen his hand, since the cross section of one end of the groove 32a is larger than the cross section of the other side of the groove 32a, as the clutch outer ring 31 moves in the second direction opposite to the first direction M, the blocking member 33 is pushed to the end with the larger cross section, so at this time the overrunning clutch is used to allow pivoting in the second direction opposite to the first direction.

[0038] When the user needs to hold the object in the virtual scene, after the boundary of the position of the hand of the user at least partially overlaps with the boundary of the object, the controller (e.g., the control device of the smart wearable apparatus or other external control device) sends a signal to initiate the clutch and stop the pivoting in the first direction. For the one-way clutch, the pivoting in the second direction is not stopped; and in another example which is not falling within the scope of the claimed subject-matter, for the two-way clutch, if the hand of the user is sensed to move in the second direction (that is, releasing the object), the control signal can be used to release the braking of the clutch, which is not limited here.

[0039] In an optional embodiment, the plurality of hinge mechanisms 20 includes a first part of hinge mechanisms corresponding to the knuckles of the finger, such as the hinge mechanisms corresponding to the finger in FIG. 1, and further includes a second part of hinge mechanisms corresponding to the middle of the palm, such as two long-strip hinge mechanisms in the palm of FIG. 1, wherein these long-strip hinge mechanisms can be used for passive bending without being connected to the brake.

[0040] As can be seen from the above, the smart wearable apparatus provided by the present invention makes the user feel his/her knuckles grip objects tightly to a maximum extent to provide the sense of gripping and holding, thereby making the user feel as if he/she was gripping and holding the object in the virtual scene. Compared with the prior art, the present invention does not concentrate on increasing or improving sensors to improve the smart wearable apparatus, instead, starts with the gripping sense characteristic of the user and fundamentally provides the user wearing the smart wearable apparatus with the sense of griping the object.

[0041] In the present invention, the overrunning clutch can be used to stop a pivoting in one direction and allow a pivoting in the other direction, and when the user wants to "release" the object in the virtual scene, the action of the user is not restricted, which improves the sense of reality during use.

Embodiment 2

[0042] The second embodiment of the present invention further provides smart wearable equipment, including the exemplary smart wearable apparatus 100 described above. As shown in FIG. 4, the smart wearable equipment further includes the case 200 and the position sensor 300.

[0043] The case 200 can provide a virtual scene through built-in software and hardware, and the position sensor 300 is configured to collect at least one real position of the smart wearable apparatus 100 and calculate at least one corresponding virtual position of the smart wearable apparatus 100 in the virtual scene.

[0044] In one embodiment, as shown in FIG. 4, the position sensor 300 is arranged on the smart wearable apparatus 100, such as a VR glove. In other embodiments, the position sensor 300 may also be arranged on other locations, for example, the position sensor 300 is worn separately on a hand of the user, or the position sensor is arranged at other position for sensing the activity of the hand, and the like. The position sensor 300 is independent of the smart wearable apparatus 100.

[0045] At least one position sensor 300 may be provided. If two or more position sensors 300 are provided, the shape and current position of the hand of the user can be simulated according to the actual collected position data, and converted by the conversion program into the virtual scene to obtain the shape, position and boundary of the hand of the user in the virtual scene. If only one position sensor 300 is provided, the position sensor 300 can collect the current position of the hand, and the position of the hand can be simulated using the built-in simulation program of the software installed in the case after considering the general size of human hands. Then, the simulated position of the hand is converted by the conversion program into the virtual scene to obtain the shape, position and periphery of the hand of the user in the virtual scene.

[0046] The object that exists in the virtual scene has the corresponding coordinates thereof in the virtual scene, and the position of each point of the hand of the user in the virtual scene can be obtained and calculated by the position sensor. Therefore, when the virtual position of the smart wearable apparatus 100 in the virtual scene partially overlaps with the boundary of the object, the case 200 can output a control signal to the controller 40 of the smart wearable apparatus 100. The controller 40 sends a signal to the brake 30, and then the brake 30 stops the corresponding hinge mechanism 30 to prevent the relative pivoting of the first portion 11 and the second portion 12 of the rigid body 10.

[0047] As can be seen from the above, the smart wearable equipment provided by the present invention includes the case, the position sensor and the smart wearable apparatus. The position sensor is configured to obtain the real position and convert the real position into the position in the virtual scene. The smart wearable apparatus makes the user feel his/her knuckles grip objects tightly to a maximum extent to provide the sense of gripping and holding, thereby making the user feel as if he/she was gripping and holding the object in the virtual scene. Compared with the prior art, the present invention does not concentrate on increasing or improving sensors to improve the smart wearable apparatus, instead, starts with the gripping sense characteristic of the user and fundamentally provides the user wearing the smart wearable apparatus with the sense of griping the object.

[0048] As preferred in the present invention, in combination with the smart wearable apparatus relevantly described in the first embodiment, the one-way clutch such as the overrunning clutch can be used to stop a pivoting in one direction and allow a pivoting in the other direction, and when the user wants to "release" the object in the virtual scene, the action of the user is not restricted, which improves the sense of reality during use.

Embodiment 3 not part of the invention

[0049] The third embodiment provides a control method of smart wearable equipment. As shown in FIG. 5, the method may include the following steps.

S501: at least one real position of the target control object is obtained;
wherein, in this step, the target control object is, for example, the hand of the user, or the aforementioned smart wearable apparatus or the like. One or more real positions of the target control object can be collected by the position sensor of the smart wearable equipment for subsequent calculation and processing.

S502: the virtual position of the target control object in the virtual scene is calculated according to the real position;
wherein, in this step, the case of the smart wearable equipment can calculate the virtual position in the virtual scene corresponding to the real position through the software. For example, the real position can be calibrated according to the coordinates of the coordinate system (such as, a space with a length of n meters, a width of n meters and a height of n meters) that is collected by the sensor to obtain the real position represented by the three-dimensional coordinates (x, y, z). When the real position is transmitted to the software, the coordinate position in another virtual coordinate space is calculated as (x1, y1, z1). The solution of calculating the virtual position according to the real position is existing in the prior art, which is not repeated here.

S503: when the virtual position is determined to at least partially overlap with the boundary position of the virtual object, a control signal is output to stop the pivoting of at least one hinge mechanism of the target control object in the first direction;
wherein, in this step, a virtual object to be held by the user exists in the virtual scene, the virtual object has a boundary position, and the boundary position is, for example, composed of a plurality of coordinate points. When the virtual position of the target control object at least partially overlaps with the boundary position, the pivoting of at least one hinge mechanism of the target control object in the first direction is stopped, so that the user feels he/she has gripped the target control object.

[0050] As can be seen from the above, the control method of the smart wearable equipment provided by the present invention can control the smart wearable apparatus according to the virtual position and the boundary position of the virtual object to enable the user to have the sense of griping, so that the user can feel as if he/she was griping the object in the virtual scene. Compared with the prior art, the present invention fundamentally provides the user wearing the smart wearable apparatus with the true sense of griping the object.

[0051] The preferred embodiments of the present invention have been described above, but any change and modification may be made to these embodiments once those skilled in the art have mastered the basic creative concepts. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present invention.

[0052] Finally, it should be noted that in this specification, relational terms, such as first and second, are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "include", "compose" or any other variant thereof is intended to cover non-exclusive inclusion so that a process, method, article or terminal device which includes a series of elements includes not only those recited elements, but also other elements that are not explicitly listed, or elements inherent in such a process, method, article or terminal device. Without more restrictions, the element defined by the statement "includes a" does not preclude the existence of other identical elements in the process, method, article, or terminal device that includes the element.

In this specification, the specific embodiments are used to explain the principle and implementation of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention.

In summary, the contents of the specification should not be understood as a restriction on the present invention.
