近年来手势识别技术的快速发展，基于手势识别技术的人机交互应用系统的建立使得人机交互的发展前景广阔。从

手形、手势和手形手势的建模出发，介绍了模板匹配、特征提取、神经网络和隐马尔可夫模型4 种手势识别的方法，并且综述

了基于手势识别技术人机交互的发展，详细介绍了3 类人机交互系统：漫游型系统、编辑型系统和操作型系统。-The rapid progress of techniques in hand posture and gesture recognition provides a promising approach for human-computer

interaction (HCI) and based on this progress many applications are established. Basic concepts of hand posture and hand gesture, two

modelingmethods of hand posture, two key problems of hand gesture and four recognition techniques are reviewed. And three types of

HCI systems influenced by hand gesture recognition are introduced in detail.
