title: A noncontact measurement of saccadic eye movement with two high-speed cameras.
abstract: A noncontact method for measuring saccadic eye movement with two high-speed cameras is proposed. The method is based on image processing for acquiring the center gravity of one pupil of the subject and also on stereo photogrammetry for estimating three-dimensional coordinate of the pupil. The proposed method was examined through experiments using a imitated eye ball and using a real human subject. The results showed a possibility of the method for the measurement. Since dynamic characteristics of the saccadic eye movement is reported as a promising index for monitoring human vigilance level according to the author's previous research works, this method can be utilized for accident prevention system in the future. However, there is still room for improvement in measuring accuracy and stability to the body motion in terms of its practical use.
