Intuitive FOV movement is possible in VR space using a head-tracker attached HMD. However, objects of attention are not exactly detected with only measurement of head movements. An eye-tracker is required to determine gaze areas, but they have bad influences on using binocular HMD. In this study, electrooculography (EOG) has been mounted on the HMD with a head-tracker. By this EOG, the screen of HMD was not hindered and head movements were allowed. Disk electrodes and 3-axis gyro-sensor were attached on the HMD to evaluate performance of this system. Additionally, digital filters were used as denoising algorithm. Experiments showed that time of detected eye movements was 0.37 seconds and accuracy of EOG was 69%. These findings suggest that rough gaze directions are detectable by combining the EOG and the gyro-sensor.
