摘　　要：随着对交互和高效利用资源的需求的增加,用户渴望与远程多通道图形应用程序进行实时可视化和交互。由于大多数此类应用程序通过除鼠标和键盘外的其他设备进行交互,因此必须支持这些设备的远程交互。目前,这种远程交互可以通过修改应用程序的源代码实现。当源代码不可访问时,该方法不可行。提出一个基于函数调用截获的、轻量级的分布式框架,在不修改应用程序的源代码的情况下实现这些设备的远程交互。基于该框架,实现了分布式DirectInput系统。实验结果表明通过集成该系统与远程交互系统,在局域网上,用户能对远程的、由手柄驱动的多通道图形应用程序进行实时可视化和交互。With the increasing demand on interaction and efficient resource utilization, users aspire to the ability of visualizing and interac- ting with remote multi-channel graphics applications in real time. Since many of these applications are designed to be interacted with devices other than mouse and keyboard, to support the remote interaction of these devices is required. Currently, achieving such remote interaction re- quires modification of the source code of applications, which is impossible when the source code is inaccessible. This paper presents a light- weight distributed framework based on function invocation interception, requiring no access to application source code can these devices realise remote interaction. Based on such a framework, we implemented the Distributed Direetlnput system. Experimental results show that by integra- ting this system into our remote interaction system, users can visualize and interact with remote multi-channel graphics application driven by joystick in real time under LAN.
