I kind of wondered how they did 3D without 3D glasses. I knew that a parallax barrier would work, but I figured it would have too small of a sweet-spot to be very good (i.e. shift a little to the left or right and the 3D would fail). I guess it’s big enough, though I haven’t actually tried it in person.
Based on their description, this system wouldn’t work for TV or movies – unless they dramatically increased the number of images handled by the system, creating a whole series of sweet spots.
