Abstract
Computer-based lecture presentation systems have been widely used in classroom. Yet the teachers can not edit the slides in class according to the actual classroom feedback, which goes against active learning. Although Ink annotation can to some extent make up for lack of interactions, the geometry teachers’ requirements for freely drawing graphics and showing dynamic geometric figures in class can not be met. We propose a pen-based intelligent dynamic lecture system for geometry teachers, with which teachers can not only add annotations with ink, but also demonstrate dynamic graphics with pen gestures and draw graphics with sketches. A kind of Rule-And-Context-Based mode switch method is adopted to intelligently speculate the users’ intentions to make sure that using Ink, Gesture and Sketch together do not confuse the users. An informal evaluation has been setup and the result seems quite positive.
