Abstract

There is provided an environment sensing system for the deaf/hearing-impaired. A user wears a personal unit for notifying him/her of a sound event in its surrounding environment. The personal unit is also in communication with a central station, for the user to request immediate assistance. When receiving a sound event message from a sound detection unit in the environment, the personal unit vibrates and displays a notification on a screen. At any time, the user may request immediate assistance to the central station using push buttons located on the personal unit. The central station may contact the user by displaying inquiries or messages on the screen. The user may then confirm that immediate assistance is actually required or communicate more information to the central station using the push buttons.

an input module for inputting said immediate assistance request, said request to be communicated to said central station using said transceiver;

said transceiver being further for receiving an inquiry message initiated by said central station in response to said request,

said output module being further for displaying said inquiry message, and

said input module being further for inputting an answer to said inquiry message, said answer to be communicated to said central station using said transceiver.

2. The personal unit as claimed in claim 1, further comprising a vibrator activated upon reception of said sound event message for warning said user said reception.

3. The personal unit as claimed in any one of claim 1, wherein said output module comprises a display screen for displaying an icon representative of said sound event message.

4. The personal unit as claimed in claim 1, wherein said output module comprises a display screen and said inquiry message comprises a text to be displayed on said display screen.

5. The personal unit as claimed in claim 1, wherein said input module comprises buttons for selecting the answer to be inputted.

6. The personal unit as claimed in claim 1, wherein said input module comprises an immediate assistance button for inputting the immediate assistance request by pressing said button.

7. The personal unit as claimed in any one of claims 1 to 6, wherein said sound event is one of a door bell detection event, a fire alarm detection event, a phone ring detection event, a sound detection event and a baby cry detection event.

8. A method for communicating an immediate assistance request to a central station using a portable personal unit for notifying a deaf/hearing-impaired user of a sound event in its surrounding environment, the method comprising:

receiving, on the portable personal unit, a sound event message representative of said sound event detected in said environment;

providing a notification of said sound event message on the portable personal unit;

inputting an immediate assistance request on the portable personal unit;

communicating said request to said central station;

receiving an inquiry message initiated by said central station in response to said request, on the portable personal unit;

displaying said inquiry message on the portable personal unit;

manually inputting an answer to said inquiry message on said portable personal unit; and

transmitting said answer to said central station.

9. The method as claimed in claim 8, wherein said providing a notification of said sound event message comprises displaying an icon representative of said sound event message on said portable personal unit.

10. The method as claimed in any one of claims 8 and 9, wherein said providing a notification of said sound event message comprises activating a vibrator for warning said user of the reception of said sound event message.

11. The method as claimed in claim 8, wherein said communicating said request comprises:

transmitting said request to a central station interfacing unit located in the surrounding environment of the portable personal unit, using a transceiver; and

said central station interfacing unit transmitting said request to said central station.

12. The method as claimed in claim 11, wherein said central station interfacing unit transmitting said request to said central station is made using a wired technology.

13. The method as claimed in claim 12, wherein said central station interfacing unit transmitting said request to said central station is made using a central station phone line.

14. The method as claimed in claim 8, wherein said receiving an inquiry message comprises:

receiving said inquiry message on a central station interfacing unit located in the surrounding environment of the portable personal unit;

said central station interfacing unit transmitting said request to the portable personal unit; and

receiving said inquiry message on the portable personal unit.

15. The method as claimed in claim 8, wherein said displaying said inquiry message on the portable personal unit comprises displaying a text inquiry message on a display screen.

16. The method as claimed in claim 8, wherein said manually inputting an answer comprises pressing a button associated with the answer, on said portable personal unit.

17. The method as claimed in claim 8, wherein said inputting an immediate assistance request on the portable personal unit comprises pressing a button on said portable personal unit.

18. The method as claimed in any one of claims 8 to 17, wherein said sound event is one of a door bell detection event, a fire alarm detection event, a phone ring detection event, a sound detection event and a baby cry detection event.
