Pre-recognition analysis on stroke characteristics such as the count, size and position of each stroke in real-time as it is drawn improves recognition accuracy. After each stroke, the set of strokes is weighted toward handwriting or gesture. The system uses a gesture threshold size to distinguish between gestures and handwriting. The system also uses the stroke count to distinguish between the two inputs, relying on the knowledge of the allowable number of strokes in a gesture. The count information may also be used in conjunction with the stroke size information to weight the set of strokes between gestures handwriting. Once the stroke size crosses a gesture vs. text size threshold, the result is weighted toward gestures. By examining the `white space` between strokes and the juxtaposition of the strokes, a gesture vs. text determination can be made with high accuracy.

[ We claim:] [1.] A method of distinguishing between handwriting and gesture input to a pen based computer system, comprising the steps of:detecting a set of strokes input by a stylus to the computer system;prior to recognition, sequentially analyzing the set of strokes for either a first set of characteristics indicative of a handwriting input or a second set of characteristics indicative of a gesture input;prior to recognition, after analyzing each stroke, for either the first or the second set of characteristics of all analyzed strokes, categorizing the set of strokes as gesture or handwriting input; andbased on whether the set of strokes is categorized as gesture or handwriting input, Performing gesture recognition or handwriting recognition on the set of strokes to recognize the set of strokes as a particular gesture or handwriting.
