| 摘 要： | 人-计算机交互系统(HCI)是当前计算机与人自然交流的研究热点之一。从眼眶周围记录的眼电图信号(EOG)可以转化为坐标去控制计算机。本文讨论了与眼球扫视运动相关的EOG波形在时域、频域内的分析及特征的提取，并应用简单贝斯分类算法建立原型系统。通过对实验数据的统计分析，初步验证了将眼电图信号转化为坐标点的可行性。

| Abstract: | Human computer interactions(HCI)have become an important area of research and appliacation.Electrical potentials recorded by horizontal and vertical electrooculography(EOG) can be transformed into cursor that is used to control computer.In this paper ,the eignevalues of eye movement related DOG signal on time and frequency domain have been analyzed and extracted,and this control method have been verified practical by developing a simple prototype system based on Bayes rule. |
