The subject disclosure is directed towards eyewear configured as an input device, such as for interaction with a computing device. The eyewear includes a multi-touch sensor set, e.g., located on the frames of eyeglasses, that outputs signals representative of user interaction with the eyewear, such as via taps, presses, swipes and pinches. Sensor handling logic may be used to provide input data corresponding to the signals to a program, e.g., the program with which the user wants to interact.
