Abstract: A computer mouse for use with a computer, including: a base with a lower surface configured for sliding across a work surface and having at least one portion forming part of a base contact plane; an upper body extending from the base; a contact sensor; an optical movement sensor system capable of detecting mouse movement relative to the work surface, a communication system, for communicating computer-readable movement and/or position data signals from the device to a computer, wherein the mouse is configured to operate in a first mode when orientated in a first orientation, and a second mode when orientated in a second orientation when the base contact plane is inclined with respect to the first orientation, and wherein the optical movement sensor system is configured to capture an image of the work surface in both the first and second modes to determine device movement in both modes.
