基于B/S结构的多终端交互式幻灯片演示系统
Multi-terminal interactive slide show system based on B/S structure
摘要
Abstract
To meet the need of large-scale multimedia teaching and in allusion to the limitations of the traditional Power-Point(PPT)slide show,an interactive slide show system based on B/S structure was designed and implemented. The system can analyze and converse the existing PPT files. During the presentation process,the synchronized play of slides from multiple slave control terminals can be controlled by the master terminal. The interaction of text,voice and electronic whiteboard between the teacher and students is supported to facilitate the multimedia teaching. The practical test and application results show that the system can conveniently complete the presentation and interaction of multimedia slides on multi-terminals,and has good per-formance in cross-platform and real-time interactivity,which is of instructive significance for the current multimedia teaching.关键词
