12ms puts it at about 90hz latency. I play games on a 144hz screen, and I can tell the difference between 90 and 144 hz, and that's on a bad screen at an arms length from my face that's definitely not trying to convince me I'm looking at reality.
It'll probably be in the same ballpark as a good transparency mode on headphones -- close to indistinguishable in small bursts, but long term causes alienation/lack of presence.
> Creepy Eyes fake transparency (a work around for the fact that you look dumb wearing ski goggles on your face) - The realistic 3d facetime avatar (a work around for the fact that you look dumb wearing ski goggles on your face, creepy eyes isn't a good enough work around for facetime, and you need an external camera to do facetime).
And transparency mode on modern headphones is a waste of time since you can just take them off. I agree both the demoed features suck and I don't want them in my conference calls, but stuff like that is a necessary bridge for a new product category. Hard to call that wasted effort.
