摘　　要：基于多屏协同的智能电视人机交互系统定义了移动设备对智能电视的远程操控和文本输入的通信机制,以解决用户对智能电视的操作不灵活的问题,尤其改善用户的文本输入操作体验。该通信机制稳定、可扩展性强,适用于不同平台的远程操控和文本输入需求。该系统基于UPnP协议实现了快速连接移动设备和智能电视,并且以Android系统广播机制和输入机制为依据,提出了基于虚拟驱动的输入扩展机制,达到了原生鼠标键盘事件的效果,实现了利用移动设备对智能电视进行交互控制的设计。实验证明,该人机交互系统,具有无缝连接、操作简单的优点,尤其适合用户进行文本输入操作。The smart TV human-computer interaction system based on multi-screen collaboration defines a communication mechanism for mobile devices in regard to remote control and text input on smart TV so as to solve the problem that user's control on smart TV is not flexible,in particular to improve user's experience of text inputting operation. This mechanism is stable and has high scalability,and is suitable for the requirement of remote control and text input on different platforms. Based on UPn P protocol the system implements fast connection on mobile devices and smart TV,and presents the virtual drive-based input extension mechanism based on Android system broadcast mechanism and input mechanism,this achieves the effect of the native mouse and keyboard events,thus realises the design of using mobile devices to interactively control smart TV. Experiments show that this human-computer interaction system has the advantages of seamless connectivity and simple operation,and is particularly suitable for users in text input operation.
