Abstract: A writing apparatus comprises a housing and a keyboard mounted in the housing and having keys representing symbols of a language. Each key is moveable from a rest position. Sensors sense position of each key and develop a signal representing position of each key. A controller is operatively connected to the sensors for monitoring the signal. The controller is configured to determine if any of the keys are pressed by monitoring the position of each key and for any given key determining if an amount of change in position from the rest position for the given key is greater than a select movement amount and rate of change in position for the given key is greater than a selected velocity amount, and generating change in an output state for the given key responsive to the given key being pressed.
