摘　　要：从硬件、软件、应用领域及发展趋势4个方面对基于光学的多点触摸技术进行了综述.硬件部分主要介绍了硬件系统结构,搭建光学多点触摸系统的5种技术以及搭建大尺寸多点触摸屏时所要使用的投影技术.软件部分首先介绍了如何从硬件平台获取触点信息,然后介绍了手势识别的相关内容,给出了多点触摸软件框架并对触点信息如何通过TUIO协议传递给上层应用程序作了说明.最后对多点触摸技术的应用领域和发展趋势进行了阐述.Multi-touch technology was reviewed based on optics from four aspects： hardware, software, application domains, and development trends. For hardware, the structure of the hardware system was introduced along with five technologies which are used to build optical multi-touch systems and the projection technology that is used to build a large multi-touch screen. Concerning software, the way to retrieve the information of contacts from a hard- ware platform was introduced first, and then the relevant contents of gesture recognition were shown. The multi-touch software framework was given, and at the same time the method of passing the information of contacts to the upper applications through the TUIO protocol was explained. Finally, this paper describes the application domains and development trends of multi-touch technology.
