Handwriting Recognition

The tablet and stylus can be used to replace a keyboard, or both a mouse and a keyboard, by using the tablet and stylus in two modes:

  • Pointing mode: The stylus is used as a pointing device as above.
  • On-line Handwriting recognition mode: The strokes made with the stylus are analyzed as a "electronic ink", by software which recognizes the shapes of the strokes or marks as handwritten characters. The characters are then input as text, as if from a keyboard.

Different systems switch between the modes (pointing vs. handwriting recognition) by different means, e.g.

  • by writing in separate areas of the tablet for pointing mode and for handwriting-recognition mode.
  • by pressing a special button on the side of the stylus to change modes.
  • by context, such as treating any marks not recognized as text as pointing input.
  • by recognizing a special gesture mark.

The term "on-line handwriting recognition" is used to distinguish recognition of handwriting using a real-time digitizing tablet for input, as contrasted to "off-line handwriting recognition", which is optical character recognition of static handwritten symbols from paper.
