Abstract

The present subject matter relates generally to the method and apparatus for using haptics for fitting hearing aids. The application of haptics technology to hearing aid fitting system software is provided. A graphical user interface with a touch screen for hearing aid fitting provides tactile response to a user adjusting hearing aid parameters using the touch screen. The interface provides feedback to assist the user in rapid and accurate hearing aid fitting. Other variations include using a touch pad for the tactile response.

Claims

1. A method for fitting a hearing aid worn by a wearer with a fitting system, comprising:

programming an interface to the fitting system adapted to provide a tactile response to a user of the system during a fitting session.

2. The method of claim 1, wherein programming an interface includes programming a touch screen interface.

3. The method of claim 1, wherein providing a tactile response includes providing a sensation of a user'"'"'s finger against a solid object as an indication of an upper or lower limit on a range of parameter adjustment.

4. The method of claim 1, wherein providing a tactile response includes providing a sensation of greater or lesser drag against a user'"'"'s finger as an indication of approaching an upper or lower limit on range of parameter adjustment.

5. The method of claim 1, wherein providing a tactile response includes providing a sensation of light pressure clicks as an indication of an increase or decrease of a predefined increment of parameter adjustment.

6. The method of claim 1, wherein providing a tactile response includes providing a sensation to simulate texture and pressure of controls on a faceplate of the hearing aid.

7. The method of claim 1, wherein providing a tactile response includes providing a sensation to simulate pressure and touch characteristics of a wall mounted on/off light switch for user reference to on/off status of the hearing aid.

8. The method of claim 1, wherein providing a tactile response includes providing a sensation of pinching, wherein a pressure level of pinching is scaled to hearing aid compression ratio such that an increased pressure level corresponds to an increased compression ratio.

9. The method of claim 1, wherein providing a tactile response includes providing a first sensation to a user'"'"'s right hand and a second sensation to a user'"'"'s left hand, wherein the first sensation corresponds to a response value for a hearing aid adapted for a right ear and the second sensation corresponds to a response value for a hearing aid adapted for a left ear, to indicate differences in response values for a right and left hearing aid.

10. The method of claim 1, wherein programming an interface includes programming a touch pad interface.

11. A fitting system for fitting a hearing aid, the fitting system executing on a computer, the system comprising:

an interactive touch screen for entries of one or more user preferences by a user of the fitting system during a fitting session, the touch screen adapted to provide a tactile response to the user during the fitting session; and

memory to store the one or more user preferences,

wherein the computer is adapted to control the touch screen to provide the tactile response, and further adapted to store the one or more user preferences.

12. The system of claim 11, wherein the tactile response includes a number of pulses sent to the touch screen to indicate a corresponding number of modified parameters.

13. The system of claim 12, wherein the number modified parameters include a number of modified memory locations.

14. The system of claim 11, wherein the tactile response includes multiple pressure responses for accommodating multiple user fingers touching the screen.

15. The system of claim 14, wherein the multiple pressure responses correspond to different channels of the hearing aid.

16. The system of claim 11, wherein the tactile response includes incrementally increasing pressure responses as the user drags a finger across an audiogram displayed on the screen from a first frequency to a higher frequency on the audiogram.

17. The system of claim 16, wherein the pressure response increases incrementally on the audiogram at 0.5 kHz, 1 kHz, 2 kHz and 4 kHz.

18. The system of claim 11, further comprising a network connection for transmitting or receiving the tactile response.

19. The system of claim 18, wherein the network connection includes an INTERNET connection.

20. The system of claim 11, wherein the computer communicates wirelessly with the hearing aid.
