| Popis: | This study investigates the permissible value of horizontal binocular disparity when gazing at a three-dimensional (3D) display based on ocular accommodation function. For the closely perceived image on the 3D display screen, the crossed disparity of +1.0° and of +0.5° were given and for the far image, which gave the image far away from the screen, the uncrossed disparities of −1.0° and of −0.5° were taken. The disparity was 0° when the image was displayed on the screen. When the disparity was +1.0° and the stereoscopic image had been perceived, the accommodative response became significantly larger in comparison to that at 0°. An accommodation lead was observed significantly at a disparity +1.0°. The tolerance of binocular disparity on the 3D display based on the physiological aspect of ocular accommodation is thus suggested to be less than +1.0°. |
