Researchers at the University of St Andrews suggest that it is possible to experience 3D vision with only one eye rather than two.
The technology for the creation of 3D experience is based on the thinking that the two visual images seen through each eye is combined in the visual cortex of the brain, producing the sense of depth needed for the 'special' 3D effect. However the new study, published in the journal Psychological Science, suggests that 3D vision is possible by simply looking through a small hole.
AdvertisementThe findings can help people who have just one eye or difficulties with double-eye vision and also lead to development of other cheaper ways through which 3D experience can be created.
"We have demonstrated experimentally, for the first time, that the same 'special way' in which depth is experienced in 3D movies can also be experienced by looking at a normal picture with one eye viewing through a small aperture (circular hole). Our findings and preliminary results suggest that our method could be used to allow people with misaligned eyes (strabismics) to experience what it is like to actually see in 3D", Dr Dhanraj Vishwanath said.
