Abstract
The description relates to user control gestures. One example allows a speaker and a microphone to perform a first functionality. The example simultaneously utilizes the speaker and the microphone to perform a second functionality. The second functionality comprises capturing sound signals that originated from the speaker with the microphone and detecting Doppler shift in the sound signals. It correlates the Doppler shift with a user control gesture performed proximate to the computer and maps the user control gesture to a control function.
