> It's actually astonishing how often developers accidentally switch left and right eyes in code – effectively having the ICD be negative rather than positive – and it takes ages to consciously notice, if ever. But your subconscious notices, and you will end up being sick, and you won't know why!
This is the most amazing anecdote in the article to me. Is the brain able to use this reversed-perspective data to determine distance and scale, or does it give up and pick a single eye? Is it like those glasses that flip your vision upside down, in that you'll get used to it after a week, and have to readjust to the way things normally are afterwards?
- cetra3 7y agoI think it might be a bit like the hollow face illusion: https://en.wikipedia.org/wiki/Hollow-Face_illusion https://en.wikipedia.org/wiki/Hollow-Face_illusion When I was playing an early version of HL2 VR if you walk right up to the wall, the crowbar you are holding goes through it but the wall stays at the same distance. A very weird feeling.

- tomjakubowski 7y agoIs it like how a Magic Eye picture looks when you cross your eyes to "match" the sides rather than relax and focus in the distance?
- MrEldritch 7y agoYes, exactly analogous!
