Patent ID: 7724238

Claim:
A mouse for controlling a cursor on a screen of a computing device, the mouse being reversibly expandable and collapsible between a flat generally planar configuration and a popped configuration, the mouse being operable in both configurations, wherein said mouse comprises a planar arrangement of a generally rigid base and a flexible upper surface affixed to a rotation axis at each end, and wherein said expansion from the flat to the popped configuration is achieved via a sliding motion that shortens and compresses the flexible upper surface to form a curved or arched profile due to the reduced chord length between opposing ends, wherein said mouse base supports rigid side-panels which are stored parallel to the base in the flat configuration and can hinge and reversibly lock at a generally upright position to the base and upper surface in order to provide support to the upper surface as the overall mouse is slid into the popped configuration, wherein the mouse is reversibly lockable in at least one of the flat configuration and the popped configuration.
