This paper provides a brief summary of the major attributes of pen-based interfaces, including: — The use of pen devices for pointing and selecting tasks, — The use of pen-based gestures for command invocation, — Issues and applications of electronic ink, which is used for various graphics and informal note-taking tasks, and — A summary of current issues with pen-based handwriting recognition.
