Rotationally desensitized unistroke handwriting recognition

摘要

A Unistrokes symbollogy in which strokes of like profile (i.e., strokes that are distinguished from each other by their rotational orientation) are rotationally offset from each other by at least 90° is provided. This provides a sufficient tolerance for disambiguating these strokes when they are written into hand-held pen computers and the like by users having widely divergent hand writing styles.
