A hand grip apparatus for receiving operator input includes a body having a proximal end and a distal interface end for coupling to an input apparatus. A first control lever is attached to the body and extends away from the proximal end and terminates in a finger grip for receiving one of the operator's fingers. A second control lever is attached to the body and extends away from the proximal end terminating in a thumb grip for receiving the operator's thumb. Movement of at least one of the control levers is operable to produce a first control signal representing the movement. An input control is included on the body between the grip ends and has an actuator surface angled towards the finger grip end and configured to produce a second control signal in response to actuation by one of the operator's fingers.
