Microsoft's Glasses-Free 3D Display

[wraggster]

The Microsoft Applied Sciences Group has developed a new lens that lets you watch three-dimensional content without 3D glasses. The new lens is thinner at the bottom (about 6mm) than at the top (11mm) and steers light to a viewer's eyes via LEDs along its bottom edge. The 3D display uses a camera to track viewers so that it knows where to steer the light; the idea isn't new, but the required CPU power is now affordable and small enough to pull it off on a large scale.
