Virtual pointing device for touchscreens
First Claim
1. A method for directing a computer system, having at least a processor, memory, and touchscreen, to create a virtual pointing device on the touchscreen, comprising the steps of:
- (a) detecting a handprint of a hand placed on the touchscreen;
(b) determining if pre-defined characteristics exist for the handprint based on the shape and size of the handprint;
(c) 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
(d) if pre-defined characteristics do not exist, creating a generic virtual pointing device under the at least a portion of the hand.

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.
