Abstract:
1. A method for determining if received strokes are gestures comprising: receiving at least one stroke as a user input to a computing device; normalizing said at least one stroke; computing Chebychev polynomials for coordinates of the at least one stroke; passing said polynomials to one or more previously computed Bayes nets for known gestures, each of said gestures being associated with a predetermined command to be executed by said computing device; determining whether said polynomials correlate with one or more of said Bayes nets; if said polynomials correlate with one or more of said Bayes nets, then causing said computing device to process said at least one stroke as a gesture and execute a corresponding command; and if said polynomials do not correlate with any of said Bayes nets, then causing said computing device to withhold rendering said at least one stroke as ink until a predetermined plurality of non-correlating strokes have been accumulated, and rendering said plurality of strokes as ink after said plurality of non-correlating strokes have been accumulated.
