Abstract (in Japanese) (See Japanese page) 
(in English) Head movement during video oculography is considered as a major source of artifacts. However, little quantitative information is available as to how pupil detection is affected by head motions. Here we show that the accuracy of pupil detection was significantly higher with head fixation devices than without ones in humans. Moreover, a preliminary study in a macaque monkey indicated that some visual targets on a screen or reward apparatus could improve pupil detection under non head-fixated conditions. These results confirmed the importance of had fixation in video oculography.
