Method and apparatus continuing action of user gestures performed upon a touch sensitive interactive display in simulation of inertia

At least one non-transitory computer-readable storage medium containing a program of machine-readable instructions executable by a digital data processing machine to perform operations for operating an interactive display system including a display having a touch-sensitive display surface, the operations comprising:

• detecting a position of each contact site at which the display surface experiences physical contact;
• utilizing each contact site's position history to compute velocity data for the respective contact site;
• utilizing at least one of the following to identify occurrence of one or more user gestures from a predetermined set of user gestures:
• the position history, the velocity data;
• wherein each user gesture corresponds to at least one predetermined action for updating, as a whole, all imagery presented by the display;
• commencing the action corresponding to the identified gesture;
• and
• responsive to a user gesture terminating with a nonzero velocity across the display surface, continuing the action corresponding to the gesture so as to simulate inertia imparted by said gesture.
