If that's confusing, the video straightens it right up.
i3D app brings glasses-free 3D to iOS, tracks your gaze like a creepy portrait tracks Scooby Doo (video)
i3D is a new app that can create a glasses-free 3D display on iDevices, using a technology known as Head-Coupled Perspective (HCP). Developed by the folks from the Engineering Human-Computer Interaction (EHCI) Research Group, HCP uses a front facing camera to track the movements of a user's head, allowing the app to adjust the display accordingly. The result is a monocular 3D screen that creates the illusion of looking into a box. If the concept sounds a little familiar, it could be because Google unveiled a similar headtracking feature for Ice Cream Sandwich during the opening keynote at this month's I/O event. And by "similar" we mean "pretty much the exact same thing." i3D is now available for free in the iTunes Store and runs on the iPad 2, iPhone 4 and fourth generation iPod Touch. You can compare both iOS and Ice Cream Sandwich 3D generators after the break (Google's demo kicks off around the 16:50 mark).
3D (sort of) on your iPad without glasses
There's a nifty little free demo you may want to pick up that uses the iPad camera to do some head tracking and create a kind of faux 3D on your iPad display. We took a look at an early demo for this last month, and now the app has arrived for your downloading pleasure. Unlike stereoscopic 3D systems, i3D doesn't send two images to your eyes. What i3D does instead is show you several scenes that change perspective as you tilt your iPad side to side and up and down. The effect does not depend on the gyros built into the iPad, but instead uses the camera to track the position of your head and render a changing perspective in real time. The demo was developed by Jeremie Francone and Laurence Nigay, and as you use it, you can just imagine the possibilities for games and educational apps. The app only works in portrait view at present. There is an iPhone version, but screen size makes a difference and the 3D effect on the iPad version seems stronger. I've seen some similar demos that use the built-in gyro, but they don't seem as responsive as this app. It's hard to give you a feel for this app in a static screen shot, so I'd suggest that you check out the fascinating video on the next page to get a good idea how it all works. %Gallery-124231%
i3D's glasses-free prototype screen aims to take on all of 3D's problem areas
Uncomfortable, expensive glasses and a lack of 3D content -- that'd be the short list of stuff we dislike about current 3D TVs, but coincidentally it also happens to be the exact issues i3D is determined to wipe out with its glasses-free technology. We stopped by to meet with the young, Los Angeles-based company last week, and though it obviously isn't the first to develop spec-less displays, its proprietary hardware and software combo was really impressive. The demo of a 7-inch prototype really tells the whole story -- and we encourage you all to see it for yourself in the video after the break, though obviously you won't be able to experience all three dimensions from your standard LCD. Our time screen-gazing was pretty breathtaking, even though the smaller display was far from immersive. As for the viewing angle issue that's the Achilles' heel of the others, i3D claims its technology allows for three-dimensional viewing at close to 90 degrees, though it was hard for us to really evaluate that on such a small screen. The coolest thing by far is the software's ability to convert 2D to 3D content on the fly. One second we were watching a two-dimensional clip of Cars and then with the tap of the 3D button the car was driving off the screen. While this isn't the first company dabbling in 2D conversion, we haven't seen any others doing this without the glasses, and i3D does claim it can convert any resolution programming. We'll have to see it to believe it, but if it does work and the quality lives up to what's being promised there'd go our lack of content issue! Apparently the price of the technology should add at most 20 percent to that of a current HDTV, but here's where we tell you that we wouldn't be surprised if it took years for all this technology to make into Best Buy's Magnolia Home Theater section. Given the fact that we met with the company in a backyard, we'd say that both it and its technology are in the early stages. But hey, it makes you feel better that someone is working on that 3D frustration list, right? %Gallery-88839%
