摘　　要：电视控制需要适合的体感选单。身体部位型选单和饼型选单各有优缺点。综合了两者的优势,用身体部位型选单保证稳定的启动,用饼型选单保证识别率,并对其改良以实现层级展开的效果。系统前处理进行数据整理,字母提取器对运动状态作出离散描述,以正则表达式描述原子动作,通过产生式规约实现动作识别。测试结果表明有较高的识别率和很好的用户满意度。A suitable motion sensing menu system is demanded for TV control. Both body menu and pie menu have their disadvantages. The advantages of the two is synthesized. Body menu is used to insure a stable start-up, while pie menu, improved for presenting layers of expansion, is used for its high recognition ratio. The pre-processing part readies the data for further processing. Letter retrieving part describes motion states in a discrete manner. Regular expression is used to capture atomic actions. Gestures are finally recognized by production reduction. Test results show the system has good recognition ratio and a high level of user satisfaction.
