Or almost 50% more than 4K, per eye.
>Saccades to an unexpected stimulus normally take about 200 milliseconds (ms) to initiate, and then last from about 20–200 ms, depending on their amplitude (20–30 ms is typical in language reading).
Are you sure? Seems like plenty of time - even current iphone camera since many generations have 240fps and most android even handle 720fps mode - current iphones should handle it probsbly even in software (except their camera has quite high latency last time when tested) but they handle it in hardware R1 chip anyway. Since they using probably something like truedepth IR pattern projector, with 720fps grayscale camera should be easy to have very fast motion detector just checking only regions around dots
Works pretty well for games and media though, these are semi-popular in the Steam Deck community.
These also have zero processing and require a device to connect to, there is no positional tracking either so the display floats wherever you move your head to.
But it's also the one that is most open to competition because it has no ecosystem link. There are already half a dozen alternatives at $400-$1k type range that give you virtual monitors. eg: the XReal Air [0]. It's interesting that even while they are generating some interest, it doesn't seem to me that AR glasses as monitors on their own are taking off yet in a mainstream way.
So it's going to be a question of how much more it can add to that or do better than that. Is just branding it Apple enough? Maybe. But I feel like it needs at least something else than purely being a monitor to compete with the alternatives.
