Super multi-view 3D displays reduce conflict between accommodative and vergence responses

A conflict between accommodation and vergence is one possible cause of visual fatigue and discomfort while viewing conventional three-dimensional (3D) displays. Previous studies have proposed the super multi-view (SMV) display technique to solve the vergence-accommodation conflict, in which two or more parallax images enter the pupil of the eye with highly directional rays. We simultaneously measured accommodative, vergence and pupillary responses to SMV 3D displays to examine whether they can reduce the conflict. For comparison, responses to two-view stereo images and real objects were also measured. The results show that the range of the accommodative response was increased by the SMV images compared with the two-view images. The slope of the accommodation-vergence response function for the SMV images was similar to that for the real objects rather than the two-view images. We also found that enhancement of the accommodative range by the SMV images is noticeable with binocular viewing, indicating that vergence-induced accommodation plays an important role in viewing SMV displays. These results suggest that SMV displays induced a more natural accommodative response than did conventional, two-view stereo displays. As a result, SMV displays reduced the vergence-accommodation conflict.
