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 detecting a handprint of a hand placed on the touchscreen, determining if pre-defined characteristics exist for the handprint based on the shape and size of the handprint, if pre-defined characteristics exist for the handprint, creating a virtual pointing device under at least a portion of the hand in accordance with the pre-defined characteristics, and if pre-defined characteristics do not exist, creating a generic virtual pointing device under the at least a portion of the hand.
