(Peter Molyneux is a bit known for promising a bit too much beforehand)
I think this video is just pure concept, it works
too quick and exact to be believable.
I suppose this should already work, when people have
specific Markers (like a hat, Marker-balls to attack to your hands)
Its really hard for the computer to track the actual
person and its movement without reference points.
Important is, that this kind of control is quick, and
not too laggy.
Good Idea. But too much concept-fiction. I would like
to see a real application running in a real world.
