Abstract: A computer mouse including a base with a lower surface for sliding across a work surface, the lower surface having a first base contact footprint with contact feet for supporting the mouse on the work surface. An upper body extends from the base with a palm rest extending from the rear of the mouse upper. At least one trigger button is located forward of the palm-rest and at least two primary buttons are located forward of the trigger button. A recess is formed underneath the trigger button and is at least partially formed by the underside of the trigger button. An optical movement sensor is included along with a communication system, for communicating with the computer.

Abstract: A computer mouse (1) including a base with a lower surface (4) for sliding across a work surface (5), the lower surface (4) having a first base contact footprint (7a) with contact feet (6a-6f) for supporting the mouse (1) on the work surface (5). An upper (8) extends from the base (3) with a palm rest (9) extending from the rear (18) of the mouse upper (8). At least one trigger button (13e, 13f) is located forward of the palm-rest (9) and at least two primary buttons (13a, 13b) are located forward of the trigger button (13e, 13f). A recess (14) is formed underneath the trigger button (13e, 13f) and is at least partially formed by the underside of the trigger button (13e, 13f). An optical movement sensor (15) is included along with a communication system, for communicating with the computer (2).

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.
