<p>A mouse (1) which senses six degrees of motion arising from movement of the mouse within three dimensions. A hand-held device includes three accelerometers (17-19) for sensing linear translation along three axes of a Cartesian coordinate system and three angular rate sensors (14-16) for sensing angular rotation about the three axes. Signals produced by the sensors (14-19) are processed to permit the acceleration, velocity and relative position and attitude of the device to be conveyed to a computer (23). Thus, a person may interact with a computer (23) with six degrees of motion in three-dimensional space. Computer interface ports (7-12) and unique address identification (37) ensure proper communication with the computer (23) regardless of the orientation of the mouse.</p> |
