Abstract
A computer pointing device including a supporting member which supports or forms a part of a conventionally-known QWERTY keyboard. The supporting member is movable relative to a supporting surface and includes a sensor for sensing directional movements or directional pressures of the supporting member relative to the supporting surface. Alternatively, a palm rest can be movably coupled relative to the supporting member and include a sensor for sensing directional movements or pressures applied to palm rest. The sensor can be coupled to a computer to control a pointer on the computer display. By these structures, a user can operate the computer pointing device without moving the hands from the QWERTY keyboard by moving the QWERTY keyboard and/or the adjacent palm rest relative to a supporting surface.
