带振动触觉反馈的三维体感人机交互系统

　　本项目利用加速度传感器，振动电机及USB与上位机的通信构建了一个带振动触觉反馈的人体动作测试的三维人机交互系统。该系统由四组相同的驱动模块、一组数据接收模块和中央处理模块构成。测试模块包括射频通信，加速度传感器和振动电机可置于人体四肢(肘或膝关节的纵向两侧)，用于提供人体动作信息和触觉震动反馈信息。基于嵌入式处理器的中央处理模块与测试驱动模块之间利用无线方式进行数据通讯。该中央处理单元收集由4个加速度传感器传输的人体动作数据，通过对接收数据的处理完成对人体动作的识别，并结合特定的虚拟场景(多媒体图形画面)反馈不同的触觉振动信息，构建一个基于体感的人机交互系统。中央处理单元可提供与PC机或电视机的接口，从而实现包括游戏娱乐和教育等在内的多种应用系统。

　　Novel body-gesture driven human computer interaction system with haptic vibration feedback

　　This project using acceleration sensor, vibration motor and USB and superordination machine to construct a communications with the human body movements tactile feedback vibration testing system of three-dimensional human-machine interaction. This system consists of four groups of the same test module and a central processing module. Testing modules including rf communications, acceleration sensor and vibration motor can be put in human limbs (elbow or knee longitudinal side), used to provide information and tactile vibration body movements feedback information. Based on embedded processor of central processing module and test driver module based on wireless data communication mode. The central processing unit collects by eight accelerometer data transmission of human body, through the movement of body of data processing, and recognition of the specific virtual scene multimedia graphic picture) (the different vibration information feedback, to build a touch of human-computer interaction based on the body. The central processing unit can be supplied with a PC or television interface, so as to realize education and entertainment, including games, multiple applications.
