Abstract
A computing device may include a keyboard, a switch in mechanical communication with an underside of a key arranged in the keyboard, a processor, a transmit line electrically connected to the processor, a sense line electrically connected to the processor, and the transmit line and the sense line are selectively connectable through the switch when the key is depressed, memory in communication with the processor, and programmed instructions stored in the memory that, when executed, cause the processor to identify changes in capacitance from the sense line when the key is not depressed, identify a hand gesture performed proximate the keyboard based on the changes in capacitance, and execute an action based on at least one the identification of the hand gesture.
