Brief Description of the Drawings
[0030] For assisting understanding of the present disclosure and to show how embodiments may be put into effect, reference is made by way of example to the accompanying drawings in which:
Figure 1 shows schematically an example of a system according to an embodiment described herein;
Figure 2 shows schematically an example of an apparatus which is part of the system of Figure 1 according to an embodiment described herein; and
Figure 3 shows schematically an example of a flow diagram of a method of operating the apparatus of Figure 2 according to an embodiment described herein.
Detailed Description
[0031] Existing apparatus for assisting people with hearing impairment rely on visual information to indicate an emergency situation to a user. Accordingly, they may be ineffective in circumstances where visual information cannot be perceived by the user. For example, the user may have a visual impairment. The user may be asleep. The user may not be able to wear the apparatus because s/he is having a shower, a swim or practising another activity that is incompatible with wearing the apparatus.
[0032] Figure 1 shows schematically an example of a system according to an embodiment. The system comprises a watch 2, a television set 4, a tablet computer 6, a laptop computer 8, a mobile phone 10 and a server 12 connected to a network 14. The network 14 may be a local area network and/or a wide area network (e.g. Internet). In some examples, not all of a television set 4, a tablet computer 6, a laptop computer 8, a mobile phone 10 and a server 12 are required or used.
[0033] The watch 2 is indirectly connected to the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 and the server 12 via one or more routers 16. The watch 2 may communicate with the routers 16 over a medium range wireless communication link (e.g. Wi-Fi link).
[0034] The watch 2 is directly connected to the television 4, the tablet computer 6, the laptop computer 8 and the mobile phone 10. The watch 2 may communicate over a short range wireless communication link (e.g. Bluetooth link).
[0035] Figure 2 shows schematically an example of the watch 2 shown in Figure 1 according to an embodiment.
[0036] The watch 2 comprises a sound detection unit 20 for detecting a sound signal in the environment of a user. The sound detection unit 20 may comprise a microphone.
[0037] The watch 2 comprises a haptic output unit 22 for outputting a haptic signal. The haptic signal may comprise a vibration signal, a heat signal, a braille signal, an electric shock signal or other. The haptic output unit may comprise a vibration motor, a heating resistance, a braille display, an electrode or other.
[0038] The watch 2 comprises a visual output unit 24 for outputting a visual signal. The visual signal may comprise a text, an image, a light (the colour and/ or flashing frequency of which may be adjustable for example) or other. The visual output unit 24 may comprise a display, a light emitting diode or other.
[0039] The watch 2 comprises a communication unit 26 for communicating with the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 and the server 12. The communication unit 26 may comprise a Bluetooth communication unit, a Wi-Fi communication unit or other.
[0040] The watch 2 comprises a power unit 28, a processing unit 30 and a memory unit 32. The memory unit 32 contains instructions which when executed by the processing unit 30 allow the watch 2 to perform the method of Figure 3 (described in further details below). The memory unit 32 further comprises a sound database storing predetermined (i.e. predefined) sound signals.
[0041] The detected sound signal may comprise a name (e.g. name of the user and/or specified names of one or more other people), a siren (e.g. an ambulance siren, a police siren, a fire brigade siren), an alarm (e.g. a fire alarm, an earthquake alarm, a hurricane alarm, a flood alarm), a car horn, a voice (e.g. a human voice as opposed to a machine generated voice), one or more words or phrases in a specific language such as "look out", "help", "beware", or other.
[0042] The sound database may be populated by the manufacturer during manufacture and/or by the user after purchase. For example, the user may program the watch 2 to download and store a predetermined sound signal stored on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12. The user may also program the watch 2 to capture a sound (e.g. specific words or phrases, including for example specific names, the sound of a user's dog barking, etc.) and store the captured sound in the sound database. In this way, the sound database can be customized by the user.
[0044] Figure 3 shows schematically an example of a flow diagram of a method of operating the watch 2 according to an embodiment.
[0046] In step 304, the sound detection unit 20 determines whether a sound signal is detected. If a sound signal is detected the method goes to step 306. If no sound signal is detected the method loops back to step 304.
[0047] In step 306, the processing unit 30 processes the detected sound signal to perform sound recognition. The processing may include analogue to digital conversion, time to frequency conversion, filtering, speech detection or other.
[0048] The processing unit 30 determines whether the detected sound signal is associated (i.e. matches) with a predetermined sound signal in the sound database in the memory unit 32. If the detected sound signal is associated with a predetermined sound signal in the sound database in the memory unit 32, the method goes to step 308. If the detected sound signal is not associated with a predetermined sound signal in the sound database, the method goes to step 318.
[0049] In step 308, the processing unit 30 identifies an emergency situation. For example, the processing unit 30 may determine that a car is coming when the detected sound signal matches with an ambulance siren or a car horn. The processing unit may determine that a fire is ongoing when the detected sound signal matches with a fire alarm or other.
[0050] In step 310, the haptic output unit 22 outputs a haptic signal and/or the visual output unit 24 outputs a visual signal. The haptic signal and/or the visual signal may be based on the emergency situation. For example, the intensity or the frequency of the haptic signal and/or the visual signal may vary based on the type of emergency situation or the degree of emergency of the emergency situation.
[0051] In step 312, the communication unit 26 connects to the television 4, the tablet computer 6, the laptop computer 8 or the mobile phone 10.
[0052] In step 314, the communication unit 26 instructs the television 4, the tablet computer 6, the laptop computer 8 or the mobile phone 10 to remotely display an indication (i.e. a notification) of the identified emergency situation. Alternatively, the visual output unit 24 locally displays an indication of the identified emergency situation.
[0053] The indication may comprise a text (e.g. "Warning: ongoing fire!", "Warning: ongoing hurricane!", "Warning: ongoing flood!", "Warning: ongoing earthquake!", "Warning: ongoing tsunami!", "Warning: ongoing thunder!" or other), and/or an image (e.g. a flame icon, a hurricane icon, a flood icon, an earthquake icon, a tsunami icon, a thunder icon, or other).
[0054] In an implementation, the watch 2, the television 4, the tablet computer 6, the laptop computer 8 or the mobile phone 10 checks whether there is an actual emergency situation before displaying the indication. Checking can be done by connecting to the network 14 and analysing one or more of current or breaking news items, articles, videos, podcast, images trending thereon, etc..
[0055] In step 316, the communication units 26 instructs the television 4, the tablet computer 6, the laptop computer 8 or the mobile phone 10 to display further information related to the identified emergency situation. Alternatively, the visual output unit 24 locally displays further information related to the identified emergency situation.
[0056] The information may comprise a text (e.g. fire brigade phone number, flood related newspaper article, hurricane instructions, transcription of a podcast related to an ongoing earthquake) and/or an image (e.g. map of the building showing the location of closest exits, safe rooms or fire extinguishers).
[0057] The information may be stored locally on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or remotely on the server 12.
[0059] In step 318 (i.e. for the case that the detected sound signal is not associated with a predetermined sound signal in the sound database of the watch 2), the communication unit 24 connects to some other apparatus, such as for example one or more of the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12. It will be understood that the communication unit 24 may connect to the same or a different apparatus to the apparatus it connects with in step 312.
[0060] In step 320, the communication unit 24 transmits the detected sound signal to the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12 to remotely determine whether the detected sound signal is associated (e.g. matches) with a predetermined sound signal on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12. The communication unit 24 then receives a result of the determination.
[0061] Alternatively, the communication unit 24 receives a predetermined sound signal from the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12. The watch 2 can then locally determine whether the detected sound signal is associated (e.g. matches) with a predetermined sound signal stored on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12.
[0062] If the detected sound signal is associated (e.g. matches) with a predetermined sound signal stored on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12, the method goes to step 308. If the detected sound signal is not associated (e.g. does not match) with a predetermined sound signal stored on the television 4, the tablet computer 6, the laptop computer 8, the mobile phone 10 or the server 12, the method goes to step 322.
[0063] In step 322, the processing unit identifies a lack of emergency situation and loops back to step 304.
[0064] An advantage of the watch 2 over existing apparatus for assisting people with hearing impairment is that it does not only rely on visual information to indicate an emergency situation to a user. Accordingly, the user can be notified of an emergency situation even where visual information cannot be perceived by the user.
[0065] Moreover, it does not only rely on sound signals stored on the watch 2 to identify an emergency situation. Accordingly, the identification may be more accurate.
[0066] It will be understood that although the watch 2 has been described as an example of an embodiment, other embodiments may encompass other wearable or non-wearable apparatus.
[0067] The watch 2 as shown in Figure 2 is represented as a schematic block diagram for the purposes of explaining the functionality of the watch 2 only. Hence, it is understood that each unit of the watch is a functional block for performing the functionality ascribed to it herein.
