Dynamic lens and monovision 3D displays to improve viewer comfort

摘要

Stereoscopic 3D (S3D) displays provide an additional sense of depth comparedto non-stereoscopic displays by sending slightly different images to the twoeyes. But conventional S3D displays do not reproduce all natural depth cues. Inparticular, focus cues are incorrect causing mismatches between accommodationand vergence: The eyes must accommodate to the display screen to create sharpretinal images even when binocular disparity drives the eyes to converge toother distances. This mismatch causes visual discomfort and reduces visualperformance. We propose and assess two new techniques that are designed toreduce the vergence-accommodation conflict and thereby decrease discomfort andincrease visual performance. These techniques are much simpler to implementthan previous conflict-reducing techniques.
