Sorry, should have elaborated more in the article. You DO have to stand in a particular spot - I think there were several spots for each TV. There are several circles on the screen with arrows in them, and once you stand in the right place, the arrows disappear. It's a prototype, so I think the final product will do away with the circles (except during calibration maybe?), and the 3D will work from multiple viewing angles.
