Abstract:
1. A computer implemented method performed in a system including a processor coupled to digital data storage and a display having a touch-sensitive display surface, wherein the method comprises the steps of: in the digital data storage, storing a record defining a collection of multiple user gestures executable by touching the display and for each user gesture storing an assignment of at least one of multiple prescribed operations of modifying subject matter presented by the display; for each of at least one touch experienced by the display surface, the processor observing one or more characteristics of the touch; based on data including the one or more characteristics 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 one or more characteristics of one or more touches 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.
