摘　　要：多点触摸屏的应用程序开发是当前的研究热点。Linux multi-touch(MT)协议是Linux输入子系统的一个标准协议,定义了多点触摸设备驱动程序的数据传输规范,有着广泛的使用范围。识别和处理多点触摸屏驱动程序的数据是多点触摸屏应用最基本的功能。本文采用有穷自动机的思想,设计了一个可以识别符合Linux multi-touch协议规范数据的多点触摸屏中间件。中间件提供外部接口供应用程序使用,可以减少程序开发人员的重复工作,提高开发效率。The application development of multi-touch screen is becoming highlighting. The Linux multi-touch protocol is a standard pro- tocol for Linux input subsystem,it defines the data transmission specification of multi-touch device drivers and is widely used. The identify and deal with multi-touch screen driver data are the basic functions of multi-touch screen applications. In this paper, a multi-touch screen middleware which is in line with the Linux multi-touch protocol specification data is designed by using the finite automaton. The middleware offers an external interface for the applications,which can reduce duplication of work program developers to improve the de- velopment efficiency.
