Pen based computer handwriting instruction
First Claim
1. A handwriting instruction system for use by a student comprising:
- acquisition system for recording pen tip motion information corresponding to each of a plurality of individual strokes used to form a predetermined character input by said student;
a feature extraction system that analyzes said pen tip motion information to extract features from said character input, said features selected from the group consisting of writing speed, pen tip pressure, timing between strokes, stroke quality, slant of characters, position of characters, and orientation angle of the pen;
an attribute evaluation system that analyzes said features and that generates a set of handwriting attributes by combining said features into main attributes from which is formed an overall evaluation of said predetermined character, said attributes are selected from the group consisting of size, shape, slant, and spacing; and
a handwriting expert system that compares said attributes with the attributes of a template for said predetermined character, and synthesizes recommendations to said student on how the quality of said predetermined character may be improved and mediates the presentation of a subsequent handwriting lesson.

Abstract
A method and system for performing instruction of handwriting skills by animated display of the required stroke motions with simultaneous audio verbal description of these same motions, including the means for a student to practice this lesson with use of a pen based input device by which the pen motion is captured, displayed on a computer monitor, and communicated to an evaluation algorithm which rates the quality of the writing. Based on this handwriting evaluation, the system includes means to provide visual and auditory reward, and generate the subsequent instructions and exercise for the student using embedded expert teaching knowledge. In the preferred embodiment, a tablet with a fastening mechanism fixes into position the paper duplicate of the handwriting lesson presented on the computer screen and the pen writing device is a special ballpoint pen capable of leaving a hard copy trace of the student writing.
