基于笔交互的几何教学系统

Geometric Teaching System Based on Pen-Based Interaction

随着电算化教学在广大中小学校中的推广,教师的板书教学同电算化教学之间的矛盾日益突出。针对这个问题该文基于人机交互中的笔交互技术,设计并实现了一套几何教学系统,并将双向几何约束的相关技术应用于该系统中。该系统有效地结合了当前教师丰富的板书教学经验和计算机对信息强大的处理能力,具有广阔的应用前景。

With the wide spread use of computer in teaching,confliction between teaching with computer and teaching with blackboard is increasingly protruding.To solve this problem,this paper designs and implements a geometric teaching system based on PUI (Pen User Interface),and applies technique of bidirectional geometrical constraint to this system.This system combines the advantage of the teachers' experience about writing on blackboard with computer's strong ability of information processing,so it will have a good future.
