Pen-Based User Interface Based on Handwriting Force Information

Abstract

Pen-based computing attracts many researchers recent years. Pen-computer generally uses pen tip position and pen pressure information at present. Actually, the force between the pen tip and writing plate is a three-dimensional vector, which represents more important information in the process of writing. In this paper we firstly describe an innovative force sensitive device (F-Tablet) for pen-based computing, and it can acquire three perpendicular forces and position of the pen-tip simultaneously. The second part deals with problems of Pen-User Interface design based on this tablet. Experimental results show that this pen-user interface considers context awareness and some characteristics of user cognition. Furthermore the pen-user interface can complete most functions of keyboard and mouse.
