Humans can see 3-D images with only one eye, according to new research, suggesting a future in which the technology could become cheaper and more accessible.
Simply looking through a small hole is enough to experience 3-D, says Dhanraj Vishwanath, a psychologist at the University of St. Andrews in Scotland. His research was published in the journal Psychological Science.
The 3-D technology that’s currently used in movies and other media relies on two visual images, one from each eye, combining in the viewer’s brain to produce 3-D’s extra layer of depth.
But Vishwanath’s research suggests that both eyes aren’t needed.
“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).
