ABSTRACT:
An apparatus, method, and memory direct a computer system, having at least a processor, memory, and touchscreen, to create multiple, moveable virtual pointing devices. The method includes the steps of detecting at least two hands placed on the touchscreen, creating a virtual pointing device under at least a portion of each hand positioned on the touchscreen, in response to detecting a first hand no longer being positioned on the touchscreen, determining if at least one of the other hands is no longer being positioned on the touchscreen, and in response to two or more of the hands not concurrently being positioned on the touchscreen and detecting at least one of the hands being re-positioned on the touchscreen, determining which virtual pointing device belongs to the re-positioned hand.
