MIT researchers are making progress with their "Princess Leia" hologram demo, a system that uses Microsoft Kinect to capture live 3D data and transmit it over the Net to a holographic projector. I first saw a previous generation of this projector demonstrated more than a dozen years ago by the late holography pioneer Professor Stephen Benton. The technology blew me away then and it's come a long way, even though the effect may not translate so well in the video above. From New Scientist:
The real holographic image couldn't match the resolution achieved by special effects in the movie, (MIT professor Michael) Bove says, but adds, "Princess Leia wasn't being transmitted in real time. She was stored" in R2-D2's memory.
Bove's group started with an array of 16 low-resolution infrared cameras, spaced evenly along a metre-long line. Computer processing combined the images to generate the data needed for the 3D holographic projector at the rate of 15 frames per second.
The next step came in late December when they bought their first Kinect, and hacked the camera system made by PrimeSense of Israel, which records three-dimensional profiles by projecting a grid of laser light onto a scene. This approach, called structured light, yields resolution of 640 by 480 pixels, three times higher than each infrared camera. That was good enough to record the holographic Princess Leia scene shown here.
Whisk yourself back to the days of bulky devices, outmoded physical media, and painfully obvious visual puns with these 1990s high-tech stock photos. Literal surfing and literal webs! Large format high resolution only $399 on some stock sites!
Anarchic Adjustment was a pioneering streetwear brand and artist collective that emerged from the London punk-skate-BMX-Xerox art scene in the mid-1980s and spread like a virus when founder Nick Philip moved to San Francisco and immersed himself in the early cyberculture. Immediately, Anarchic Adjustment became the clothier-of-choice for the likes of DJ Mixmaster Morris, Joi […]

Obviously, hiring one programmer rather than two is beneficial for companies and makes Xamarin experts highly in demand.You can easily learn Xamarin online with this Xamarin Cross-Platform Development Bundle. It will teach you to use Xamarin and code […]
TV antennas are making a comeback, and the Ghost Indoor HDTV antenna is a great example of why. Unlike the old bunny ear-style antennas, this compact antenna is barely noticeable and picks up channels easily. Plus with the addition of streaming services like Netflix, we find ourselves with plenty to watch without a pricey monthly cable bill. The Ghost […]
I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
