概要

A new head-mounted-display, named as Eye-Sensing Head Mounted Display (ES-HMD), has been developed which can not only provide the user with virtual environment through visual and auditory stimuli conventionally but also monitor the user's both eyes and calculate ocular information such as pupil size, eyeblink or eye gaze point. The obtained ocular measures will be utilized for analysis of its relation to peculiar ocular characteristics under various binocular visual conditions as well as for eye gaze interaction to the display.The specifications of the developed ES-HMD are described first, followed by the discussion on the characteristics of pupil indices measured by ES-HMD; it is shown by measuring pupil that pupil sphere has better resolution to indicate pupil size than pupil diameter. A new calibration method for the eye gaze point on the display is also presented, which has better performance than conventional linear interpolation method.
