  • Input tablet system with user programmable absolute coordinate mode and relative coordinate mode segments
    Patent number: 6029214
    Abstract: A computer system includes an input pointer, a tablet having a two-dimensional tablet surface, and a data processor coupled to the tablet and operative to receive coordinate data from the tablet. The coordinate data is preferably in absolute-mode, and the data processor processes the coordinate data such that coordinate data influenced by a first segment of the tablet surface is processed in a relative-mode fashion, and coordinate data influenced by a second segment of the tablet surface is processed in an absolute-mode fashion. In consequence, the tablet is segmented for simultaneous relative-mode and absolute-mode operation. The segments can take on a number of configurations depending upon the configuration of the computer screen, the application program running, and user preferences.
