Unity tech demo shows off a lifelike digital human rendered in real-time

IMHO it's mostly due to the fact that human motion isn't really all that fluid. It's more twitchy in nature, even the eyes. I think it's due to the fact that we have to compensate for the blind spot, as well as how muscle fibers move as a unit. So for me that's the dead give away. I did notice some twitchiness in the face muscles that almost sold me, but then when she looked directly at me it all evaporated because as you said the eyes looked lifeless.

That's why I made the uncanny valley reference. The more realistic it gets, the more weirded out we become.

Up to a certain point. There exist possibilities for levels of realism (relative to the current state of the art) which breach past the uncanny valley. But it's hard to climb out of the valley - and very easy to slip into - the higher that realism goes.

Yep, and that's because organisms are more analogue than digital. There's often no logic whatsoever involved in our facial expressions. That's where an algorithm would have tremendous difficulty.
