Yet another biological difference between men and women in the brain?
danah boyd wrote an interesting piece in Quartz about her observations that men and women prioritise different depth cues. She has personal experience in a CAVE Automatic Virtual Environment that made her puke and she can’t see IMAX movies.
In short: artificial 3D environments, depth cues have to be programmed in. There are a lot of depth cues, and we don’t need all, but motion parallax is pretty easy to render in 3D, so that gets in. Motion parallax, according to boyd, is the one men’s brains pick out as the most important cue, but women prioritise on shape-from-shading, which is a lot more complicated. Therefore, for men in general, 3D environments work well, but for women, the poor rendering of shape-from-shading causes disorientation and nausea. This phenomenon may also be related to why some transsexuals experience strange visual side effects from their treatment.
If this is the case, there is indeed a problem with 3D technology. dana points out that a lot more research is needed.
I have been in the CAVE of the Centrum for Wiskunde & Informatica in Amsterdam which was totally awesome, and a very rare experience. No nausea experienced. However, IMAX theatres have been around for quite a while and are common. Some people do indeed experience motion sickness with them, but shouldn’t it have come to light by now if this was something particularly affecting women?
HT to Hank Greely for bringing this to my attention.
