A wireless EOG-based Human Computer Interface
Min Lin, Bin Li · 2010 3rd International Conference on Biomedical Engineering and Informatics · 2010
Human Computer Interface (HCI) is becoming a hot area of research. It can be developed for the disabled and many other application fields. Biopentials existed in human body, such as Electroencephalogram (EEG), Electromyogram (EMG), Electrooculogram (EOG) are used to be inputs of the HCI system. In this paper, the design scheme of a wireless EOG-based Human Computer Interfaces is presented. The detailed system diagram is shown in the paper. It consists of EOG signal acquisition, EOG filter and amplifier, ARM microcontroller and Zigbee wireless module. Also, the methods of eye gestures recognition are discussed.
