摘要:: 人机交互（HCI）是借助电子计算机技术而发展起来的一门技术科学，同时也是人类与计算机之间相互交流与通信的一种方法。眼电信号（EOG）是一种通过电极记录下来、由眼球视网膜与角膜之间电势差形成的生物电信号，在服务于肢体运动控制障碍患者方面，由EOG控制的无障碍HCI系统发挥着越来越重要的作用。本研究归纳了EOG控制的HCI 系统的建立和发展历程，对眼球运动进行探测的常用方法：搜索线圈法、红外线眼动图法、Purkinje影像追踪法、基于计算机图形学的方法和EOG进行了介绍，总结了EOG控制的HCI系统在残障人医疗辅助以及危险环境下进行作业方面的应用，最后分析了由EOG控制的HCI系统存在的局限性及其未来的发展趋势。

Abstract:: Human-computer interaction (HCI) is a technological science that has developed rapidly along with the development of computer technology, and also a method of communication and correspondence between humans and computers. Electrooculogram (EOG) recorded by electrodes is a bioelectrical signal which is evoked by the potential difference between the retina and the cornea. In the service of patients with limb movement disorders, EOG-controlled accessible HCI system play an increasingly important role. Herein the establishment and development of HCI system controlled by EOG are summarized. Several common methods for the detection of eye movements, including search coil method, infra-red oculography, Purkinje image tracing, the approach based on computer graphics and EOG are introduced. The applications of EOG-controlled HCI system in the medical aid for the disabled and the operation in the dangerous environment are also reviewed. Finally, the limitations of EOG-controlled HCI system and its future development trends are discussed.
