1. 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; and
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; and
determining 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
determining that the touch input is associated with an audio volume control and controlling the audio volume based at least in part on the indicator identifying the force intensity of the touch input;
wherein the medium of the touch input surface is made of a metal and the signal propagated in the medium of the touch input surface is propagated through the metal.

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.

19. A system for controlling an audio volume, comprising:
-
a transmitter 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 a processor coupled with the transmitter and configured to; 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; 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; 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 medium of the touch input surface is made of a metal and the signal propagated in the medium of the touch input surface is propagated through the metal.
