<p>A computer pointing device including a base portion with a lower surface configured for sliding across a work surface, a movement sensor system capable of detecting device movement relative to the work surface and generating device movement information, and a communication system capable of communicating device movement information and contact sensor signals to a computer and associated display screen. The computer pointing device includes a non-extendable nib projecting from the base portion and is configured to operate in: a pointer navigation mode, when the base portion lower surface is substantially parallel with the work surface, the computer providing on-screen pointer movement corresponding to the device movement information, and a different mode, when tilting the device about the nib such that the lower surface is non-parallel with the work surface.</p> |
