Abstract
Systems and methods for decoupling the electrical and mechanical functionality of a depressible key are disclosed. The depressible key can include a non-contact proximity sensor, such as an optical sensor, to detect motion of the keycap. The output from the optical sensor is used to determine a distance, velocity, acceleration, and a force applied during a keypress.
