Perception of depth in 3-D media
Reviewed by Fiona Rowe

The aim of this study was to evaluate the relationship between clinical measures of stereoacuity and the perception of depth in 3-D entertainment media. Fifty-seven subjects aged 16-62 years with stereopsis and no strabismus were assessed. Monocular blur was used to vary intraocular visual acuity. With increasing intraocular visual acuity difference, stereoacuity reduced. However, the subjects were able to identify depth on a Nintendo DS until suppression of one eye occurred. The authors conclude that presence of motion in stereopscic video appears to provide cues to depth, where static cues are insufficient. They propose the findings support the need to develop a dynamic test of stereoacuity.
