You're right. The same way face unlock doesn't work for some people and they inout a password every time, so it's not intractable.
I expect people for who eye tracking fails to be stuck on third party controllers for the default interface (hopefully they're supported outside of games ?).
The bummer though will be that this device is US only for its launch, so the first round of application might also not care at all about these kind of issues. Accessibility is something Apple usually cares about, but third party devs can be more casual about it.
Well Apple is only expecting less than 1M units to be sold. Must such a niche product be designed for every variation of human? Seems reasonable that if you fall outside of the most common human forms by enough standard deviations then you're just out of luck.
I think people can understand if you tell them their ear is a bit odd shaped, or their makeup throws the dectection off. But it will be weird to explain them their eye movement is really out of norm, especially after they paid 3500.
