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.
