Abstract

A controller apparatus for controlling a device comprising a support having a surface with a wall extending therefrom and along a segment of the surface. A plurality of force sensing members are positioned in a predetermined arrangement adjacent to an inner surface of the wall of the support with each member generating a signal in response to a force applied to the member. An assembly for adaptable engagement with the force sensing members is translationally movable to selectively engage and transmit a translational force to the force sensing members to develop a signal for control of a function of the device.

Claims
