MIT Media Lab develops glasses-free HR3D, supports broad viewing angles (video)

We’ve already seen plenty of glasses-free 3D HDTVs and portable devices , but a promising new technology called HR3D (High-Rank 3D) has hit the prototype phase. Engineers from MIT’s Media Lab , who developed the new solution, say that it avoids compromising on screen brightness, resolution, viewing angle, and battery life, and doesn’t require those pesky (and pricey) 3D glasses. HR3D uses a pair of layered LCDs to give the illusion of depth, with the top layer (or mask) displaying a variable pattern based on the image below it, so each eye sees a slightly different picture. Nintendo’s 3DS uses a similar technique, but with a parallax barrier instead of a second display. The designers constructed the prototype from two Viewsonic VX2265wm displays, removing the LCDs from their housings and pulling off polarizing filters and films. We’ve yet to go eyes-on with HR3D, so we’re a mite skeptical, but tech this promising is worth watching closely, and from every angle.
