1. A computer system comprising:

  • (a) a central processing unit (CPU) for executing operating system and application programs;

    (b) a memory in circuit communication with said CPU for storing operating system and application programs;

    (c) a peripheral interface circuit in circuit communication with said CPU for interfacing to said CPU coordinate type data from at least one external input device, the input device having a pressure sensitive bounded plane for detecting localized pressure applied at any location within the boundary of the plane; and

    (d) touch region definition logic associated with said CPU and said peripheral interface circuit and responding to execution by said CPU of operating system and application programs by dynamically defining a region of the input device bounded plane and associating the defined region with a region identifier responsive to input from at least one application program executing on said CPU, said touch region definition logic accepting region definition inputs relating to variable region size for the creation of the region.
