A twin mouse digitizer is provided including a mouse housing with at least one button situated thereon. A first movement tracing mechanism is situated on a bottom face of the housing for generating a first movement signal. Associated therewith is a second movement tracing mechanism situated on the bottom face of the housing for generating a second movement signal. As such, an angular orientation of the housing may be ascertained from the movement signals of the first and second movement tracing mechanism.
