ABSTRACT:
A digitizer interface that translates the digitizer-specific reports into virtual areas of the digitizer which may be divided into specific regions or virtual tablets. Each region permits the specification of individual coordinate systems or stored sequences of commands. The interface may be implemented on a host computer, in the digitizer, or in intermediate electronics. The interface allows reports from digitizers of differing data output formats to be translated into a standard format internal to the interface thereby isolating the host processor from a given digitizer's attributes. The interface may be configured to operate many digitizers from a single host.
