A user interface device having a housing and a joystick with at least three independent mechanical adjustments, each generating an associated signal responsive to the mechanical adjustment, and at least one sensor arrangement generating signals to control at least a cursor on an external device is described. Signals from the sensor arrangements and the joystick can be multiplexed together for transmission to the external device. In an implementation, the sensor arrangements generate signals responsive to changes in the position of the housing with respect to a surface on which the user interface device is placed. In another implementation, the user interface device includes a trackball, and at least one additional sensor arrangement generating signals responsive to the operation of the trackball.
