摘要
目前网上答疑系统缺乏对实时图形绘制的支持,文章提出一个基于Tablet PC的网络白板答疑系统的设计方案,阐述了基于Tablet PC SDK的笔式界面开发,基于Socket的通信功能开发,白板图形数据的编码解码等关键技术.实现了在网络白板上进行图形和文本实时交流的功能.
This paper designed a on-line Q/A system based on Tablet PC. This system collects the graph strokes using Tablet PC SDK, and sends information under the Socket technology. Under this system, drawing on a whitehoard by a pen and exchanging views immediately can be achieved.
