Technically the nVidia demo is far above the other one, but the guy the used as a model for the nVidia one shows no emotion or something, it's just some average looking dude.

In contrast, the other one shows more emotion, and looks more stylish.

It's not the 'model' that's showing no emotion, it's the tech that's unable to. Everyone has innate emotions even if they appear hidden. They're none existant here. I'm actually beginning to wonder if this is also connected with why some people can't tell the difference between good acting and bad acting.

All this realism is nice and all, but for the love of god I hope they focus on the body animation. What good is it if the character is realistic but moves like a wooden puppet.

Oh the tech is able to I'm sure, but the problem here is artistic direction. As you just said in a previous post, there is a difference in how they want to convey emotions with their respective "heads".

Again, the nVidia demo is better techwise, but the PS4 one looks very good thanks to the artistic direction it has.

You quite clearly don't understand the uncanny valley - go watch the actual Nividia presentation as it's obvious you haven't.

I do understand it I'm just not using it as a scientific term. I'm using it in it's common usage. And I did watch the Nvidia video as well as the live PS4 Quantic Dreams presentation. And I've played LA Noir.

They all fail to simulate the human face in a photorealistic manner. LA Noir is too cartoony to be creepy, but the ld man and the Nvidia demo try their hardest to not be creepy and fail.

Not being perfect =/= uncanny valley. 

If you are repulsed by the Nvidia or Quantic Dreams demo, I think you'll find yourself in a vast minority, showing the demos are coming out of the valley rather than being at the base of it as with Beowulf and LA Noir. 

Guess I'm part of that minority too then, since the nvidia gifs at the first page are creepy to me too. Especially the middle one when he smiles or something. I didn't have that with LA Noir as they still look very cartoony.
One of the characters in Heavy Rain was getting near creepy too when trying to smile, one of the female characters where the teeth wouldn't move right with the facial expressions.

I guess as long as the animation is more realistic then the rendering then it's fine (LA Noir), but when the rendering looks more realistic then the animation it becomes creepy.

Go watch the actual video - movement has a lot more to do with the uncanny valley than graphics alone; you couldn't be more wrong as it's known that movement is much more indicitive of ending up in the valley so for something like LA Noir where the movement is realistic but eveything else isn't, that will end up in the valley more than the same animations on a more believably rendered head.
