Researchers at the University of St Andrews have found that, contrary to popular belief, it is possible to see in 3D with just one eye.
Dr. Dhanraj Vishwanath, a psychologist at the University says that it is possible to experience vivid 3D vision simply by looking through a small hole.
The research, published by Psychological Science, has implications for people who have just one eye or difficulties with double-eye vision.
The study also has wide implications for 3D technology, because it suggests that there are other (possibly cheaper) methods by which the 3D experience can be created.
Current thinking is that the two visual images (one from each eye), when combined in the visual cortex of the brain, produce our sense of depth that produces the ‘special’ 3D effect.
The St Andrews study suggests that, in fact, both eyes are not necessary for this ‘3D experience’.
Dr Vishwanath said, “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).”
“While this effect has been known for a long time, it is usually dismissed. Now we have shown that it is in fact real, and the perceptual results are exactly like stereoscopic 3D, the kind seen in [Keep reading…]
