Microsoft's new lens tracks your face, steers 3D images to your eyes (video)
Glasses-free 3D has taken several forms, but most have a critical flaw -- viewers have to stand in predefined locations to get the effect. That just won't do, so Microsoft's prototyped a new approach, and it's one of the wildest we've seen. Taking a cue from Project N... we mean Kinect, cameras track the face while a special wedge-shaped lens traps bouncing light, and after the beams have reached a "critical angle," it exits towards the viewers eyes, aimed by programmable LEDs at the bottom of the screen. Since the system can beam a pair of simultaneous images to two different places, the obvious use is stereoscopic 3D, but researchers found they could also send different images to different viewers, as a sort of privacy screen. If that sounds far fetched, you're not alone -- but you'll find a video proof-of-concept at the more coverage link.
Editorial: ESPN bypasses corporate red tape with iPad and Xbox 360, wannabe innovators should take note
So, there's two ways to look at this. One would be to gawk at the fact that ESPN, the worldwide leader in sports broadcasting, is using iPads and Xbox 360 consoles -- common devices that are widely available to mere mortals -- to drive content to millions of consumers. Another would be to gawk at the fact that ESPN has somehow managed to keep its finger on the pulse of innovation, despite being swallowed by Disney and being a part of one of the planet's most monolithic corporations. Thankfully for you, we're going to cover both angles here. Our eyes were opened after stepping foot in the company's Bristol headquarters and really getting a feel for how the company views technology and its integration into programming, and it led us to a philosophical conclusion about how corporations should (but oftentimes aren't) be taking advantage of what's readily available. Ready to get schooled? Head on past the break. %Gallery-95012%
Students program Human Tetris into 8-bit microcontroller, give away schematics for free (video)
Sure, Project Natal is the hotness and a little bird tells us PlayStation Move is pretty bodacious, but you don't have to buy a fancy game console to sooth your motion-tracking blues. When students at Cornell University wanted to play Human Tetris (and ace a final project to boot), they taught a 20Mhz, 8-bit microcontroller how to follow their moves. Combined with an NTSC camera, the resulting system can display a 39 x 60 pixel space at 24 frames per second, apparently enough to slot your body into some grooves -- and as you'll see in videos after the break, it plays a mean game of Breakout, too. Full codebase and plans to build your own at the source link. Eat your heart out, geeks.
Sony and Atracsys develop 3D interface for ORs, sci-fi franchises (video)
You know what the world needs? Another company peddling their take on the touch interface as being "just like Minority Report!" Sun, Raytheon, Oblong -- it's a pretty obvious press hook (as well as a pretty awesome area of research), but every once in a while some such technology does come around that begs for a closer look. A collaboration between Sony Europe and Atracsys (a Swiss company specializing in optical tracking) ICU is a dual camera-based system that tracks and analyzes body movements in three dimensions, in real-time. Initially designed for use with a computer in a sterile operating theater, the interface not only notices subtle changes in the position of your body, arm, hand, or finger position, but it's also determine rough age, sex, or facial expression of the user. We're guessing that this bad boy has some novel gaming potential as well (count on the folks at Engadget to bring everything down to their level)! PR / videos after the break.
Microsoft's Project Natal roots revealed: 3DV Systems ZCam
We had a hunch that 3DV Systems' technology -- which we actually toyed with back at CES 2008 -- had something to do with Microsoft's newly unveiled Project Natal motion tracking solution, and today details have trickled in to us confirming as much. As the story goes, 3DV Systems was initially hoping to have the ZCam in the manufacturing process by the tail end of 2008, but Microsoft swooped in and acquired the outfit just weeks after it blew minds in January. At the time, not much thought was given to the pickup; now, however, we're treated to a bona fide ZCam brochure which details the actual specifications behind the Xbox 360's newest friend. Granted, we have every reason to believe that Natal has advanced significantly from what you'll see in the gallery below, but it's still a tasty nugget of behind-the-scenes information. Of note, the former 3DV Systems VP of Business Development was quoted as saying that the target retail price of the ZCam was $100, though it still had aways to go as of early 2008.
iPoint 3D brings gesture-based inputs to 3D displays
Just in case you've been parked out under a local stone for the past six months and change, we figured it prudent to let you know that the 3D bandwagon has totally regained momentum. So much momentum, in fact, that the brilliant minds over at Fraunhofer-Gesellschaft have decided to bust out a 3D innovation that actually makes us eager to sink our minds into the elusive third dimension. The iPoint 3D, which we're hoping to get up close and personal with at CeBIT next week, is a technology that enables Earthlings to interact with a 3D display via simple gestures -- all without touching the panel and without those style-smashing 3D glasses. The gurus even go so far as to compare their creation to something you'd see in a science fiction flick, with the heart of it involving a recognition device (usually suspended above the user) and a pair of inbuilt cameras. There's no mention of just how crazy expensive this would be if it were ready for the commercial realm, but we'll try to snag an estimated MSRP for ya next week.[Via Physorg]
Panasonic's new 3D range sensor functions in direct sunlight
Perhaps you're looking for a way to track potential cat burglers, give your robot some spacial sense, make your UIs a little more interactive, or you simply want to keep an eye on your "compound." Panasonic has just released detailed specs for its 3D range sensor -- the first, it says, to work in direct sunlight. Exhibited at CEATEC 2008, the device emits light from several dozen LEDs to track the movements of any object in its view. The company's previous 3D range sensor didn't function well (if at all) in bright light, but the equipment now compensates for "extremely bright ambient light" by measuring it and eliminating it from the equation. Can't wait to track your loved ones' every movement? The 24 volt, USB 2.0 sensor is slated for an April 1, 2009 release. [Via Tech-On!]
Sony brewing up 1:1 motion tracking sword game for PS2 and EyeToy
This makes sense on very many levels, but at the same time we've gotta think those long-suffering PS3 owners will be a bit "hacked off" by Sony's announcement of a motion-tracking sword game headed for... the PS2. The PS2's market saturation (every man, woman and child on earth has at least two), and the EyeToy's general success (10.5 million units sold) make the combo the perfect trojan horse for fighting the good fight against Wii world domination. Sony's using new (sort of) color tracking technology to beef up the EyeToy's motion tracking that will let it detect and track brightly colored objects, instead of just motion, for two new EyeToy: Play games due for the holidays this year. The one we've really got our eye on is the kiddie-oriented Hero which is a first person perspective sword fighting game that comes complete with a fluorescent toy sword for battling kinda-almost-evil antagonists. Of course, none of this would be disappointing in the slightest if Sony would just work PS2 backwards compatibility into its fully capable PS3, and hey, maybe they'll surprise us. Nudge, comma, nudge. Wink. Wink.[Thanks, Seth B]
Researchers turn brushing your teeth into child's play
Kids -- they hate brushing their teeth. Sure, we try and show them pictures of zombie faces and toothless seniors, but it just doesn't work. Finally, someone has come up with a solution to the problem: make it fun. Researchers at the National Taiwan University have devised a scheme which turns brushing your teeth into a webcam-tracked video game. Using an LED-studded toothbrush, a camera mounted above a mirror, and an LCD display, kids can watch plaque and debris get annihilated from a cartoon mouth while they scrub their choppers. The system is able to track detailed, three-dimensional movement of the child's hand, covering 24 separate areas of the mouth. Kids who tested the system were found to brush twice as well as those who hadn't used it, but were also extremely cocky about their perfect teeth. Check the video after the break to see the magic happen.[Via Gizmo Watch]
Minute springs monitor controller motion
CNN reports on some of the motion-sensitive parts that make the PS3 and Wii controllers possible. These special sensors are based on tiny springs that make circuits when jolted, while sensitive meters measure the flow of electricity through the connection.How tiny are the parts? The silicon pieces that flex against the springs weigh about a millionth of a gram. And they only move slightly when the controller shakes -- the distance of 10 to 100 hydrogen atoms -- but their position can still be measured.The sensors have existed for years but were only recently cheap enough for games, at less than $1 per axis, making motion tracking the new arms race in game control. Will the 360 -- or next Xbox -- have motion control?
