Abstract
An operator input device includes an operator interface mechanism operable by an operator, a position sensor, a brake controller, and a resistive actuator. The operator interface mechanism is moveable in at least first and second directions along an axis. The position sensor is coupled to the operator interface mechanism for transmitting an operator interface mechanism position signal as a function of the position of the operator interface mechanism. The brake controller is coupled to the position sensor for receiving the operator interface mechanism position signal and responsively transmitting a brake signal. The resistive actuator is coupled to the brake controller and the operator interface mechanism and receives the brake signal and responsively applies a resistive force to the operator interface mechanism.
