Abstract
Abstract Disclosed are an integrated mouse tray and mouse for a portable computer and method of operation therefor. The computer, including the mouse tray of the present invention, includes: (1) a chassis having a footprint and containing components of the computer, the components including an interface circuit for communicating with a mouse, (2) a mouse electrically coupled to the interface circuit, the mouse free to move about a substantial plane to produce signals for transmission to the interface circuit and (3) a mouse tray member movably mounted to the chassis and capable of assuming a deployed position whereby the mouse tray extends substantially out of the chassis footprint, a substantially planar surface of the mouse tray providing an area on which the mouse is free to move to produce the signals, the mouse tray member further capable of assuming a stowed position whereby the mouse tray is retracted substantially to within the chassis footprint. The mouse tray member provides a portable, integrated working surface to allow a portable computer to use a mouse as a pointing device without requiring a separate working surface. The mouse tray member includes a lip having a height greater than the height of the mouse.
