Abstract
A new-head mounted display, Eye-Sensing Head Mounted Display (ES-HMD), has been developed which can not only provide the user with virtual environment through visual and auditory stimulus conventionally but also monitor the user's both eyes and calculate ocular information such as pupil size, eyeblink or eye gaze. The information can be expected to be utilized for analysis of human internal state such as mental workload, cognitive state or longtime fatigue which affects such ocular information while watching display image. In this paper, the results of the developed HMD are introduced with respect to basic functions of ES-HMD, followed by the discussion on the basic experiment of eye tracking by using the ES-HMD.
