Headaches, blurred vision, dizziness and nausea. A delightful article on the effects of stereoscopic 3D at Bit-tech.net.
First I start with this. One needs two eye that are aligned with normal parallax vision. Meaning both eye need to have good left and right muscle control to hold the eyes in sync.
I worked for a company that developed 3d camera for 2 years. We did much testing with the general public and found many could not perceive 3d from 2d information.
I underline the word perceive! The article talk mostly about a mechanical problem with one eye. We also found many people just untrained to perceive/process the visual information of 3d from 2d information.
This reminds me of this story. Bear with me there is a point. Years ago England sponsored expeditions of exploration to Africa. They traveled heavy to say the least. The director of the expeditions tent would resemble there own homes in London. Desk’s, chairs, rugs and oil painting of the queen and more.
Once after meeting a native tribe the directer of the expedition was asked by the chief if he had a chief back in his country? The director said yes then diapered to his tent and returned with a painting of the queen. He held it up for all to see. The native crowed freaked out and all looked away. The chief went on to console the director for his leaders misfortune.
Now remember the portraits of the day subjects were painted in 3/4 position. That is not face on to the viewer but there head slightly turned. Putting the face in perspective. The problem was the native crowed was not use to this visual in formation. They perceive the queen as disfigured like a abstract Picasso painting. The natives saw one big eye, a large nose and a haft an other eye all pushed over to one side of the face.
The mind needs to develop these skills of visual perception. Like the magic eye images. We found the mind could be train to develop 3d from 2d information. I came to believe all could eventual achieve the skill. Only if they wanted to. It really is all in the mind.
This up and coming generation will have a big exposure to 2d forced 3d. For better or worse.
Thanks for posting Mick. That was very interesting to read.
