PENTOOLS - A MATLAB Toolkit for On-line Pen-Based Data Experimentation

MATLAB provides a powerful environment for rapid prototyping of research methods and techniques. Across the wide range of on-line pen computing applications there exists a series of common methods for the capture, storage, manipulation and measurement of handwritten data which are used as the basis for novel research and system architecture implementation. This paper outlines a new opensource toolkit for the MATLAB programming environment containing routines and data structures to perform common functionality manipulating dasiaon-line´ hand drawing and writing data captured in the form of a time series sequence. The routines provide capture device interrogation, feature extraction and data manipulation, enabling full integration within MATLAB, thereby providing an extensible platform for experimentation and research.
