Pen Ondrej Rohlik, Pavel Mautner, Václav Matoušek, Jürgen Kempf · 2003
Development of new text and graphical input devices is considered to be important part of humancomputer interaction by many researchers worldwide. The paper presents our experience with the text recognition methods that we have developed for a new designed electronic pen that produces signals corresponding to the movement of the pen on paper. Signals are described by a set of primitives and hidden Markov models are used for word recognition. Results of tests are discussed as well as other possible application areas of our electronic pen.
