ABSTRACT:
A method, apparatus, and article of manufacture direct a computer system, having at least a processor, memory, and touchscreen, to create a virtual pointing device on the touchscreen. The method includes the steps of measuring at least a first portion of a hand placed on the touchscreen, determining if at least one measurement of the first portion substantially matches any existing measurements stored in the memory, if a substantial match exists, reading the memory for pre-defined characteristics, and building a virtual pointing device on the touchscreen in accordance with the pre-defined characteristics.
