Abstract

A user interface incorporated onto a hearing aid includes flexible hybrid component integrating a touch sensor into a bendable display. The touch sensor, such as a capacitive sensor, includes one or more sensor elements allowing a user to control operation of the hearing aid by touching. The bendable display presents information related to the operation of the hearing aid to the user.

Claims

1. A hearing aid, comprising:

a hearing aid circuit including a microphone, a receiver, and a processing circuit coupled between the microphone and the receiver;

a hearing aid housing containing the hearing aid circuit; and

a user interface coupled to the processing circuit and including a bendable display including;

a display layer configured to dynamically display information indicative of operation of the hearing aid; and

a sensor layer on the display layer, the sensor layer including a capacitive sensor configured to sense touching.

2. The hearing aid of claim 1, wherein the bendable display further comprises a cover layer on the sensor layer for protection of the sensor layer and the display layer.

3. The hearing aid of claim 1, wherein the hearing aid housing comprises a top surface and a plurality of side surfaces, and the bendable display comprises a top display encompassing a substantial portion of the top surface.

4. The hearing aid of claim 3, wherein the hearing aid housing is an in-the ear (ITE) housing configured for an ITE hearing aid, and the top surface is a surface facing outward when the ITE hearing aid is positioned during use.

5. The hearing aid of claim 3, wherein the hearing aid housing is a behind-the ear (BTE) housing configured for an BTE hearing aid, and the top surface is a surface facing upward when the BTE hearing aid is positioned during use.

6. The hearing aid of claim 5, wherein the bendable display further comprises one or more side displays each incorporated into a side surface of the plurality of side surfaces.

7. The hearing aid of claim 1, wherein the capacitive sensor comprises one or more sensor elements each including electrodes made of a material that is mechanically flexible, optically transparent, and electrically conductive.

8. The hearing aid of claim 7, wherein the material comprises Indium Tin Oxide (ITO).

9. A hearing aid, comprising:

a hearing aid circuit including a microphone, a receiver, and a processing circuit coupled between the microphone and the receiver;

a hearing aid housing containing the hearing aid circuit; and

a user interface including a flexible hybrid user interface component incorporated onto the hearing aid housing, the flexible hybrid user interface component including a bendable display and a capacitive sensor integrated into the display, the display configured to dynamically display information indicative of operation of the hearing aid circuit, the capacitive sensor configured to receive user commands in one or more forms of touching movements.

10. The hearing aid of claim 9, wherein the user interface comprises:

a display driver circuit configured to control the bendable display; and

a sensor processing circuit configured to process signals sensed by the capacitive sensor,

wherein either one or both of the display driver circuit and the sensor processing circuit are integrated into the flexible hybrid user interface component.

11. The hearing aid of claim 9, wherein the display comprises a segment display including alphanumeric characters, a bar graph display, or a combination of the segment display and the bar graph display.

12. The hearing aid of claim 11, wherein the display is configured to display information indicative of reaction of the capacitive sensor to the one or more forms of touching movements to provide guidance for adjusting settings of the hearing aid.

13. The hearing aid of claim 9, wherein the display is further configured to function as a decorative feature.

14. The hearing aid of claim 13, wherein the display is configured to display customizable schemes.

15. A method for providing interactions between a hearing aid and a user, comprising:

providing the hearing aid with a flexible hybrid user interface component including a bendable display and a capacitive sensor integrated into the display;

dynamically displaying information indicative of operation of the hearing aid using the bendable display; and

receiving user commands by sensing one or more forms of touching using the capacitive sensor.

16. The method of claim 15, comprising displaying information indicative of reaction of the capacitive sensor to the one or more forms of touching to provide guidance for adjusting settings of the hearing aid.

17. The method of claim 15, comprising displaying one or more decorative features.

18. The method of claim 17, further comprising receiving a user selection of a display scheme and displaying the one or more decorative features according to the display scheme.

19. The method of claim 15, comprising dynamically displaying information indicative of sound volume control setting of the hearing aid.

20. The method of claim 15, comprising dynamically displaying information indicative of status of a battery of the hearing aid.

21. The method of claim 15, comprising dynamically displaying information indicative of status of equalizer or memory of the hearing aid.

22. The method of claim 15, comprising dynamically displaying information indicative of status of communication between the hearing aid and a hearing aid base.

23. The method of claim 15, comprising dynamically displaying information indicative of a time of utilization of the hearing aid.

24. The method of claim 15, comprising dynamically displaying information indicative of results of sound environment monitoring performed by the hearing aid.
