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.
Intel developing software hack for long-range WiFi
The idea of extended range WiFi has been around the block before, but amidst all the talk of mass WiMAX deployments comes a swank new idea to get vanilla WiFi out to more people without breaking any laws or relying on expensive hardware upgrades. Apparently, researchers at Intel have "created a system that lets WiFi signals, which ordinarily carry a few hundred feet, instead travel 100 kilometers, or more than 60 miles." Interestingly enough, the system supposedly relies on "modified software" running on regular WiFi equipment, and wireless access points with the newfangled software can seemingly daisy-chain directional network traffic through "several carefully aligned steerable antennas in order to eventually reach a fiber link connected to the internet." Unfortunately (for us, at least), Intel has emerging markets on the brain rather than rolling this out in the US or UK, as it reckons the "$700 to $800 long range WiFi towers" would do quite well in locales that balk at $15,000 WiMAX towers. So if you're currently stealing some dignitary's WiFi in Uganda in order to read this, fret not, as Intel's looking your way for testing "later this year."
