一种独立于应用程序的多点触摸交互中间件

摘要

在对鼠标事件特性分析和触摸手势描述的基础上,设计实现了一种基于鼠标事件映射的多点触摸交互中间件,包括声明法、映射法两种实现途径.该中间件能够不进行程序改造而在传统基于鼠标交互的应用程序上实现多点触摸,具有平台无关的通用性.最后通过在多款地理信息系统软件中的应用对该中间件进行了验证和评估.%This paper first analysed the character of mouse event,and gave out the description of touch gesture. On the basis, it designed and developed a middleware for multi-touch interaction based on mouse event reflection, including two methods-declaration and reflection. This middleware made it possible to enhance the traditional mouse-based programs with multi-touch support in an application-independent way. Finally, it presented the evaluation results of the middleware on several G1S ( geographic information system) softwares.
