1. A method of handling input streams representing strokes on a multi-point input device capable of having multiple synchronous input streams, comprising the steps of:

  • identifying each new stroke in a given frame and mapping each identified new stroke to one or more listening processes, the given frame representing a single moment in time;

    identifying each released stroke in the given frame and unmapping each identified released stroke from the respective listening process to which the stroke previously was mapped;

    implementing in the given frame each listening process to which at least one stroke is mapped, each implemented listening process being carried out based on a current state of each stroke mapped to the respective listening process; and

    repeating both identifying steps and the implementing step for each of a successive plurality of frames.
