I backed the Rift kickstarter in 2012 and have had just about every bigger HMD since. There is a difference if you don't mind black smear or if it doesn't exist.

FOV reduction help nausea, but in your post you were talking about how screen door effect reducing nausea, which I can't see any evidence for.

Either way, slapping a smartwatch to your eye is a very early 2010s thing to do and will maybe give you a bit of novelty for a minute but is not something that has any real use in the current world of real HMDs.

You are right there's a difference between not minding black smear and the black smear existing. Taste differ. You mind, I don't mind and I wouldn't mind on a blown up apple watch screen. You mentioned the massive screen door adding an enormous pixel soup. I countered that if anything this would work against nausea - my 2010 monocular was a floating tv screen with a massive screen door effect.

I'm enthusiastic about something you consider "a very early 2010 thing to do" and not having any real use case in the "current world of real HMD's". Like you I live in the current world of real HMD's. My use case is enjoying playing quake on the smallest waterproof device possible. Q1 on the apple watch can be considered a novelty, yes, but I would like to take it as far as possible, because I like retro and repurposing and I like the size of the apple watch compared to a quest.

Of course, QuakeVR on Q2 exists, Apple HMD's are on the radar and I could link my android phone with a lightweight HMD and play quake that way. Why bother? Good question

I give you the water proof aspect, though I suppose a modern phone would get you there as well. Now, if Apple ever releases a watch with a super high resolution light-field display, well, in that case I'll glue that thing to a set of sunglasses myself.
