METHOD FOR MANIPULATING A GRAPHICAL OBJECT AND AN INTERACTIVE INPUT SYSTEM EMPLOYING THE SAME

摘要

A method comprises generating at least two input events in response to at least two contacts made by pointers on an interactive surface at a location corresponding to at least one graphical object; determining a pointer contact type associated with the at least two input events; determining the number of graphical objects selected; identifying a gesture based on the movement of the pointers; identifying a manipulation based on pointer contact type, number of graphical objects selected, movement of the pointers, and graphical object type; and performing the manipulation on the at least one graphical object.
