I've long had an obsession with energy savings and heating, and I think the best way to save energy on heating is by heating people instead of building. With accurate person detection in a room, you could shine low intensity IR at their exact position to keep them warm without wasting energy on heating the rest of the room.

But yeah, I think we can all expect this will be used to monitor behaviour in stores, to spy on people in homes, to rob us and to throw more "relevant" advertising in our faces.
