Abstract

Controlling an audio volume is disclosed. An indicator identifying a force intensity of a touch input provided on a touch input surface is received. It is determined that the touch input is associated with an audio volume control. The audio volume is controlled based at least in part on the indicator identifying the force intensity of the touch input.

Claims

1. A system for controlling an audio volume, comprising:

a communication interface configured to;

transmit a signal propagated in a medium of a touch input surface prior to a touch input, wherein the signal propagated in the medium of the touch input surface prior to the touch input is an acoustic signal or an ultrasonic signal; and

receive an indicator identifying a force intensity of the touch input provided on the touch input surface, wherein receiving the indicator includes receiving the transmitted signal that has been propagated in the medium and disturbed by the touch input, and the transmitted signal propagated in the medium prior to the touch input has been disturbed by the touch input in a manner that affects a signal property of the transmitted signal; and

a processor configured to;

determine the force intensity at least in part by analyzing an effect of the touch input on the transmitted signal that has been propagated in the medium and disturbed by the touch input; and

determine that the touch input is associated with an audio volume control and control the audio volume based at least in part on the indicator identifying the force intensity of the touch input, wherein the force intensity of the touch input was at least in part determined by comparing a reference amplitude of the acoustic signal or the ultrasonic signal propagating in the medium of the touch input surface prior to the touch input to a detected amplitude of the transmitted signal that has been disturbed by the touch input.

2. The system of claim 1, wherein controlling the audio volume includes increasing the audio volume in the event the force intensity is above a threshold value.

3. The system of claim 2, wherein the threshold value is configured.

4. The system of claim 2, wherein the threshold value is dynamically determined.

5. The system of claim 1, wherein controlling the audio volume includes decreasing the audio volume in the event the force intensity is below a threshold value.

6. The system of claim 1, wherein controlling the audio volume includes increasing the audio volume in the event the force intensity is within a threshold range.

7. The system of claim 6, wherein an upper bound of the threshold range is associated with a maximum force intensity value.

8. The system of claim 6, wherein an upper bound of the threshold range is associated with a predetermined force intensity value.

9. The system of claim 1, wherein controlling the audio volume includes decreasing the audio volume in the event the force intensity is within a threshold range.

10. The system of claim 9, wherein a lower bound of the threshold range is associated with a zero force intensity value.

11. The system of claim 9, wherein a lower bound of the threshold range is associated with a non-zero force intensity value.

12. The system of claim 1, wherein controlling the audio volume includes decreasing the audio volume in the event the force intensity is within a first threshold range and increasing the audio volume in the event the force intensity is within a second threshold range.

13. The system of claim 12, wherein controlling the audio volume includes not adjusting the audio volume in the event the force intensity is below a lower bound of the first threshold range.

14. The system of claim 1, wherein controlling the audio volume includes determining a rate of change of the audio volume based at least in part on the force intensity.

15. The system of claim 1, wherein controlling the audio volume includes selecting an audio output destination based at least in part on an identifier.

16. The system of claim 1, wherein controlling the audio volume includes engaging a speakerphone in the event the force intensity meets a threshold.

17. The system of claim 1, wherein the touch input was provided at a location on the surface assigned to control the audio volume.

18. The system of claim 1, wherein the touch input was provided at a location on the touch input surface where an adjustment bar was displayed.

19. A method for controlling an audio volume, comprising:

transmitting a signal propagated in a medium of a touch input surface prior to a touch input, wherein the signal propagated in the medium of the touch input surface prior to the touch input is an acoustic signal or an ultrasonic signal;

receiving an indicator identifying a force intensity of the touch input provided on the touch input surface, wherein receiving the indicator includes receiving the transmitted signal that has been propagated in the medium and disturbed by the touch input, and the transmitted signal propagated in the medium prior to the touch input has been disturbed by the touch input in a manner that affects a signal property of the transmitted signal;
