Abstract
Touch control surfaces for electronic user devices are disclosed herein. An example electronic device includes a microphone array and processor circuitry to detect a first acoustic event based on signals output by the microphone array, the first acoustic event indicative of a first touch on a surface of the device at a first time; detect a second acoustic event based on the signals, the second acoustic event indicative of a second touch on the surface at a second time; determine a first location of the first touch and a second location of the second touch; identify the first time and the second time as occurring within a threshold period of time; identify a gesture based on the first location, the second location, and the occurrence of the first touch and the second touch within the threshold; and cause an output at the device in response to the gesture.
