Abstract
A single-axis or multi-axis joystick assembly which is operative with a minimal amount of input force or displacement. As such, the joystick assembly is especially suited for those with severe motor handicaps who have limited movement in their extremities. The joystick assembly includes a housing and a handle operatively mounted to the housing for movement relative thereto. The handle operatively engages a sensor which generates an output signal when an input force is applied to the handle. The output signal is proportional to the input force. Preferably, the sensor is a piezoelectric pressure transducer.
