A hand-held inertial mouse provides input data to a computer from which the computer can determine the translational and angular displacement of the mouse. The mouse includes accelerometers for producing output signals of magnitudes proportional to the translational acceleration of the mouse in three non-parallel directions. Pairs of these accelerometers are positioned to detect acceleration along each axis of a cartesian coordinate system such that an angular acceleration of the mouse about any axis of rotation causes representative differences in the magnitudes of the output signals of one or more of these accelerometer pairs. The translational velocity and displacement of the mouse is determined by integrating the accelerometer output signals and the angular velocity and displacement of the mouse is determined by integrating the difference between the output signals of the accelerometer pairs.

An apparatus for providing data to a computer from which the computer can determine an operator selected spatial position with respect to a reference point corresponding to a location on a display, the apparatus comprising: a chassis adapted to be held in an operator\s hand; an accelerometer mounted on the chassis for producing an output signal of magnitude proportional to the acceleration of the chassis as the operator moves the chassis from a reference point; means for integrating the accelerometer output signal to produce velocity data of magnitude proportional to the velocity of said chassis; and means for providing said velocity data to a computer so that the computer can integrate the velocity data to determine the magnitude of the displacement of the chassis from the reference point, the displacement of the chassis being indicative of its spatial position with respect to the reference point.
