基于眼电信号的无线便携式的人机交互系统

　　本项目基于ADI的ADuC7026芯片，设计一种由眼电信号控制的便携式人机交互系统。该系统主要包括信号采集与调理电路、ADuC7026处理模块、PC人机交互显示模块三个部分;通过电极采集眼电信号，经过滤波放大和电平提升后，由ADuC7026对眼电信号进行分析和处理，以识别眼球的具体运动(包括四个方向和眨眼)，并将相应的控制命令通过USB接口输入到PC中，从而控制人机交互软件。

　　该系统利用的ADuC7026芯片可高速、精确地实现眼电信号的采集及数字化，同时使用LabView编写简单易用的控制界面，可大大帮助残障人士，实用性极高。

　　Based on ADI ADuC7026 micro-controller, our project designs a human-machine interaction system controlled by electro-oculograph (EOG). The system consists of signal collecting and conditioning circuits, the ADuc7026 processing module and the human-machine interaction display module in PC. The electrical signals captured by the electrode from EOG will have a preliminary amplification, filtering and boosting in the analog circuits, and then they will be analyzed by ADuC7026 to identify eye movements including the four specific directions and winks. And then the corresponding controlling commands will be sent by wireless module, while the MCU of the receiver will transform these signals and send them to the software system on PC by USB.
