摘　　要：手势是一种自然而直观的人际交流模式,基于视觉的手势识别是实现新一代人机交互所不可缺少的关键技术。文中主要围绕手势识别展开,结合了手势识别和幻灯片系统的控制,定义了4种动态手势。通过抓捕手势移动质心,恰好避开了手势复杂多变这一缺点。以FPGA作为主要的运行平台,结合Matlab的仿真,最终实现方便快捷的课堂交互的手势识别系统。Gestures are a natural and intuitive interpersonal communication model, and vision-based gesture recognition is an indispensable and key technology which can achieve a new generation of human-computer interac- tion. This article combines gesture recognition and the control of slideshow system with four dynamic gestures defined. Arresting gesture moving centroid overcomes the shortcoming of complicated gestures. A convenient classroom interaction gesture recognition system is achieved with FPGA as the main operating platform combined with MATLAB simulation.
