Abstract

There are concerns about how a viewer is affected by viewing 3D video. Some of the harmful effects include eye fatigue, headache, and 3D sickness including nausea. The mechanisms that cause these symptoms remain incompletely understood. It is often said that during virtual 3D vision, while accommodation is fixed at the display, the directions of convergence of the two eyes intersect at the location of the stereo image. Hence, accommodation and convergence do not coincide with each other in this case. In this study, we aimed to check whether this inconsistency exists or not, for which we simultaneously measured accommodation and convergence in subjects gazing at real objects, 2D images, and 3D images. We measured accommodation and convergence in natural vision successfully. We also confirmed that accommodation is not fixed at the display, but coincides with convergent focus when gazing 2D and 3D images.
