This is great but… isn’t there something fundamentally eye-straining about capturing media at a given 'interocular' distance and then displaying it to a person at their own individual and different 'interocular' distance? Interocular, meaning distance between a pair of eyes/lenses

I don't think they're just taking the images and projecting them onto each lens of the vision pro. Forgetting about inter-ocular distance for a second - that just wouldn't work for head tracking and letting you move around the image. Instead I assume they're using the pair of lenses to approximate a 3d model which allows for display at a variety of angles (all reasonably close to where the camera is), and then rendering from that model for the person looking at the image based on the angle they are actually looking at it from. Which solves the interocular distance problem, because you render for each eye based on where the persons eye is resulting in a distance between the two display images that doesn't have to match the camera.

Not exactly the same, but I like making stereo photos. I just use my iphone to take one photo left, move it over by a bit, then take another photo. I don't think I would notice if I was off by a centimeter or so. But maybe in VR it's different.

No. While not everyone's eyes may be spaced at the "normal" 64mm distance, delivering images shot with that spacing won't look significantly different to people with differing eye spacing. And even if they did, the distortion would be one of scale. For example, if you wanted to shoot something from a cat's POV, you'd put the lenses closer together and shoot objects closer to the camera. That would make it easier to fuse images of a mousehole right in front of your face. Things farther away would simply look "less 3-D" and therefore abnormally far a way to a human viewer.

From playing games that get that distance wrong, it doesn't give me a headache or anything, it just makes the whole world feel bigger or smaller than reality. Really frustrating in games that try to replicate a real feeling. In a driving sim, for example, it can make you feel like you're driving a toy car rather than a full sized one, or that you're a kid in the seat of your parents car. Obviously not a feeling you want to invoke unintentionally, but perhaps there's ways in software to adjust?

When I watch videos in VR i feel more "crosseyed" than when looking at virtual enviroments. Specially when things are near the camera.

No, but the scale feels wrong if it doesn't match. https://xkcd.com/941/ https://xkcd.com/941/
