摘　　要：为了满足大型多媒体教学的需求,针对传统PPT幻灯片演示的局限性,设计并实现一种基于B/S结构的交互式幻灯片演示系统。该系统能对已有PPT文件进行解析与转换,在演示过程中可以通过主控端控制多台从控端幻灯片的同步播放,支持师生间文字、语音和电子白板交互,为多媒体教学提供方便。实际测试与应用结果表明,该系统可以便捷完成多媒体幻灯片在多终端上的演示和交互,具有良好的跨平台和实时交互性,对当前多媒体教学具有指导性意义。To meet the need of large-scale multimedia teaching and in allusion to the limitations of the traditional PowerPoint(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 performance in cross-platform and real-time interactivity,which is of instructive significance for the current multimedia teaching.
