EOG based eye movement measure of visual fatigue caused by 2D and 3D displays

According to dissemination of appliance such as 3D TV and 3D games, visual fatigue estimation of 3D contents has been focused. EOG(Electro-ocular gram) is one of popular methods to measure the movement of the eye for visual fatigue estimation. However, voltage of EOG signal is depending on the eye shape or physiological state of the subject and its basis voltage is changed by the small movements of other body parts. This paper proposes an eye movement measuring method using EOG signal based on basis voltage adjustment for visual fatigue caused by 2D and 3D displays. The method resolve DC drift problem and can measure eye movement correctly without depending on head movement. Experimental results show that recall of the proposed method is 93% and the frequency of blinks and large saccade in case of 3D video is larger than those in case of 2D video.
