1. A method of recognizing word patterns, comprising:
- defining word patterns of a plurality of known words by a plurality of paths,wherein each path connects elements in a word on a virtual keyboard layout;
accepting an input as a stroke based on a virtual keyboard layout;
matching the inputted stroke to a word having a word pattern that approximates the inputted stroke; and
generating the matched word having the word pattern that approximates the inputted stroke.

Abstract
A system augments stylus keyboarding with shorthand gesturing. The system defines a shorthand symbol for each word according to its movement pattern on an optimized stylus keyboard. The system recognizes word patterns by identifying an input as a stroke, and then matching the stroke to a stored list of word patterns. The system then generates and displays the matched word to the user.
