摘要 |
A method for distinguishing between a plurality of pointers in an interactive input system comprises calculating a plurality of potential coordinates for a plurality of pointers in proximity of an input surface of the interactive input system, displaying visual indicators associated with each potential coordinate on the input surface, and determining real pointer locations and imaginary pointer locations associated with each potential coordinate from the visual indicators. |
