The man in this video is not real. He never existed. He is completely computer-generated by Snappers Mocaps. The designer can control him completely with a mouse: his expression, his gaze, and his lip movements.
The features of this software are listed at the YouTube page, including, "Compatible with all game engines and animation packages." Soon, video games will look this real, and you know humans in movies will follow quickly. If he stood still, or even moved without the cursor in a way that didn't indicate it was a demonstration, it would take you a while to realize who he is. But as soon as that realization sinks in, you enter the uncanny valley. -via Digg
