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 tasks for operating an interactive display system including a processor coupled to digital data storage and a display having a touch-sensitive display surface, where the digital data storage contains a record defining a collection of multiple user gestures executable by touching the display and where the digital data storage further contains for each user gesture an assignment of at least one of multiple prescribed operations of modifying subject matter presented by the display, where the tasks comprise:

• for each touch experienced by the display surface, the processor tracking a position history of the touch;
• based on input including the position history of one or more of the touches experienced by the display surface, the processor identifying from the collection of user gestures at least one user gesture executed by the one or more touches;
• the processor identifying the at least one prescribed operation assigned to the executed user gesture, and causing the display to begin modifying the subject matter presented by the display according to the identified operation;
• the processor using the position history to compute a final velocity for the executed gesture;
• and
• responsive to the executed user gesture ending with a final velocity exceeding a prescribed minimum velocity across the display surface, the processor causing the display to continue the identified operation to visually simulate inertia of the executed user gesture.
