Abstract

In this paper, the pen-based adaptive interface architecture for geometric teaching is presented to facilitate natural interactive sketching for geometric graphics application. Based on user-centered design, it analyzes the intent-based manipulation in terms of context based on pen gesture. By providing adaptive constraint capture and dynamic interaction this architecture can improve operation efficiency of the interface and reduce user's mental workload. Furthermore, it provides an educational application for benefiting teaching experience by preventing users from being interrupted in class.
