Abstract
Systems and methods for implementing pressure sensitive keys to produce digital signals that emulate actuation of conventional “momentary on” digital keys of a conventional keyboard. The pressure sensitive keys may be implemented to generate an alternating open/short digital signal representative of the amount of pressure applied to a given key at any given time. The open/short digital signal may be supplied as a signal representative of applied key pressure to a legacy keyboard key matrix and controller or other processing device of an information handling system that is configured to measure keyboard input based on “momentary-on” digital signals.
