Abstract:
1. In an interactive display, a method for identifying a specific user gesture comprising the steps of: displaying imagery on an imaging surface; responsive to a user contacting a touch sensor, detecting a plurality of contact locations at which the user contacts the touch sensor to control said display; responsive to a determination that a motion of a bounding box enclosing at least two of said plurality of contact locations exceeds a predetermined motion threshold and that deformation of said bounding box is less than a predetermined deformation threshold, said determination that said motion of the bounding box enclosing said at least two of said plurality of contact locations exceeds said predetermined motion threshold and that deformation of said bounding box is less than said predetermined deformation threshold being based on rates of change of particular parameters of said bounding box, identifying said specific user gesture as a pan gesture; associating said specific user gesture with a display command; and executing said display command to alter the display of said imagery.
