<p>A force sensitive key and keyboard arrangement for computers includes ten multidirectional keys which are used for enabling ten-finger typing by applying forces and no finger movement among keys is needed. Each multidirectional key capable of nine functions comprises a force sensor. The force applied by a finger tip is sensed and classified as one of either of eight directions on the horizontal plane or a pressing direction, the activated direction is then designated to a key function. Functions in the same column are discriminated by sensing different longitudinal forces. Discrimination of functions between columns and higher rows operated by the same finger is achieved through applying lateral forces. The ten multidirectional keys represent all of the functions of a standard computer keyboard. <IMAGE></p> |
