基于WiFi和体感交互的演示系统设计与实现

摘要

This research captured gesture command based on three axis gyro which built intelligent portable terminal system, and the adaptive template matching method is used for gesture recognition. The identification efficiency is improved when keeping the recognition rate. Taking Wi-Fi network as the carrier of information transmission, the gesture command is transmitted to the server to control the presentation slide show. Based on WiFi and somatosensory interaction demonstration, it can overcome problems of traditional USB laser pen, such as operation mode single, receiving distance limited and so on, meanwhile it can provide a better user experience.%基于智能手持终端系统内置的三轴陀螺仪捕获手势命令,利用自适应模板匹配方法进行手势识别,在不降低识别率的情况下,提高了识别效率.以WiFi网络作为信息传递载体,将手势命令传输到服务器,以控制演讲时幻灯片的放映.这种基于WiFi和体感交互的演示方式,能克服传统USB激光笔操作方式单一、接收距离有限等问题,提供更好的用户体验.
