Newswise — New glasses-free 3-D devices are about to hit the market, and their backers are hoping they'll make 3-D spectacles as obsolete as Smell-o-Vision. These gadgets, described as "autostereo" to distinguish them from the kind requiring eyewear, will include not only game consoles but also cameras, cellphones, and tablet computers. Among the first will be autostereo 3-D TVs, just now hitting stores in Japan, and Nintendo's 3DS handheld games console, due for release worldwide early next year.
Just how they make this magic happen varies. Right now, getting glasses-free 3-D means giving something up--brightness, for example, or the ability to watch with a friend. But developments in research labs may bring autostereo 3-D without trade-offs. Read about how the first autostereo 3-D devices work, and what autostereo technologies are under development.
