Facilitation of Stereopsis by Motion Parallax Depends on Head Movement Direction
Yasuaki Tamada, Masayuki Sato (Univ. of Kitakyushu)
Abstract (in Japanese) (See Japanese page) 
(in English) When binocular disparity and motion parallax are presented simultaneously, very large depth is perceived for diplopic images with very large disparity. This study examined the dependency of this depth facilitation on the direction of observer’s head movement. The test stimulus was a dot presented 2.5 deg above or below the fixation point with binocular disparity and/or motion parallax. The observer responded the apparent depth of test stimulus relative to the fixation point with a matching method while moving his/her head laterally or sagitally. In exp 1, the range of observer’s head position was 13 cm. In exp 2, the ranges of head position were 1.8 cm and 50 cm for lateral and sagital movements respectively, so that the ranges of stimulus motion were the same. The results showed that the facilitation occurred for lateral head movement but not for sagital movement in both experiments, suggesting that the facilitation is specific to lateral stimulus motion.
