Claim:
1. An apparatus, comprising: a hand-controllable signal-generating device, including: a signal transmitter configured for communicating the biaxial displacement signals to an external electronic processor; and a joystick on the top side of the body, the joystick including an angular-displacement detector; wherein the body has a palm rest being pivotally mounted on the joystick over the top side of the body, the palm rest including a palm contact surface, the palm contact surface having a contour for receiving a portion of a palm of a person's hand into contact at a position on the palm contact surface, the hand having one digit or a plurality of digits; wherein the angular-displacement detector is configured for generating angular-displacement signals that are representative of detected angular displacements of the palm rest over the top side of the body, and the signal transmitter is configured for communicating the angular-displacement signals to the external electronic processor; and wherein the contour of the palm contact surface of the palm rest is configured for facilitating control by the portion of the palm of the person's hand, being in contact at the position on the palm contact surface, of the displacements of the body in the two-dimensional directions over the working surface without the one digit or any of the plurality of the digits being in contact with the hand-controllable signal-generating device.
