Abstract

The invention concerns a stylus for use with a digitizing tablet. The stylus stores information which identifies characteristics of a user'"'"'s handwriting. These characteristics are transmitted to a computer when the user interfaces with the computer, and are used by the computer to recognize the user'"'"'s handwriting.
