'TeleHuman' uses Kinect for 3D holographic chat, bumps up options for contacting Obi-Wan (video)
Looks like virtual Tupac might have some company. With Kinect, you are the hologram. Besides logging in lots of quality time at a South Korean theme park, the Kinect is now doing double duty at the Human Media Lab of Queen's University in Canada thanks to a 3D holographic chat system called "TeleHuman." The setup basically creates a life-size rendering of its subject by using six Kinect sensors, a 3D projector and a cylindrical display. This allows the viewer to walk around the cylinder for a 360-degree view of the subject, giving new meaning to having someone's back during a chat. The director of the Human Media Lab says the TeleHuman could be available for $5,000 within five years. In the meantime, the tech is also being used by the research team to create a 3D anatomical model browser called the "BodiPod." The BodiPod can display various layers of the human body, which can be virtually peeled off as the viewer gets closer to the display. Check out all the 3D action for the TeleHuman and BodiPod in plain, old 2D by viewing the video after the break.
Tupac hologram performs at Coachella, keeps all eyez on him
Have you been getting a kick out of Coachella's jams and arts in Indio, California? Or, did you decide to peacefully enjoy it from home via YouTube's site? Either way, you may have heard Tupac made an on-stage holographic appearance over the weekend, performing Hail Mary and 2 of Amerikaz Most Wanted alongside Snoop Dogg. Tupac's hologram was made possible by AV Concepts in partnership with Dr. Dre's production company and Digital Domain, after reportedly working on the project for a few months. The outfits used a display technology dubbed "Eyeliner" that, with the help of a custom rig and a mechanical solution, was able to shoot out a life-sized, 3D illusion of Mr. Shakur onto the Coachella platform. Don't believe us? Hit 'em up at the source below, though we feel compelled to tell you language isn't exactly for all ages.
ZScape 3D holographic prints take maps to the next dimension, sans spectacles
As the video above shows, Zebra Imaging's so called ZScape prints pull off some pretty amazing 3D visual effects despite being based on old school hologram technology. These prints are made using a variety of 3D data sources -- think AutoCad and the like -- that are then rendered as thousands of holographic elements by recording laser light onto a single film-based material. The resulting images are easily viewed without glasses or spinning mirrors, and just require a run-of-the-mill halogen or LED light source to reveal 360-degree, full color representations -- akin to what a physical model might look like. Fancier versions can also be made using overlays and layering techniques to show more information. To date, over 8,000 ZScapes have already been developed for the US military, but surprisingly their prices range between $1,500 for a 12- x 18-inch version to $3,500 for the largest 2- x 3-foot size, making them relatively obtainable for those not on Defense Department tabs. If the video of Seattle pulling an Inception above didn't impress you enough, be sure to check another embedded video after the break.
World disappoints us once again: Japan loses 2022 3D holographic World Cup bid
Look, we don't know anything about World Cup bids. They probably have a lot to do with "infrastructure" and "taking turns" and stuff like that. But really, world? You couldn't pick Japan just this once? Japan's incredibly great 2022 World Cup bid involved projecting 3D holograms of the games live onto soccer football fields around the world, allowing folks that can't make it to Japan for the actual games to get a pretty great simulacrum, while standing next to people that look like them and are probably rooting for the same team. "I have to admit that the idea of this blows my mind away," said Japan's committee chief Kohzo Tashima. Did you get that, world? Japan was offering you 3D holographic full field broadcasts, and you just turned a cold shoulder. Congrats, Qatar, we hope you're happy with 2022, and we're sure you earned it based on whatever arbitrary metrics FIFA uses to select World Cup countries. But you'll never earn our hearts. Video of Japan's bid is after the break.
Dynamic 3D holograms can now refresh every two seconds, save galaxies in their spare time
Perhaps the biggest challenge in making holograms usable on a daily basis -- aside from having to film your subject with a million trillion cameras -- is in getting their refresh rates up to the levels we're used to with "normal" two-dimensional video. We're still a fair way away from those magical 30fps, but the University of Arizona is touting a heretofore unheard of redraw rate of once every two seconds. This is a major advance from their first dynamic holograms demonstrated two years ago, which required minutes to swap over to a new image. The current prototype is built on a 10-inch photorefractive polymer screen, with lasers beaming information onto it, though 17-inch versions are also being tested. Another present limitation is that the hologram displayed can only be of one color, but that is also subject to the continuing labors of the UA researchers, who foresee no major hurdles preventing them from eventually cobbling together full-color, fast-refreshing, and fully realized 3D holograms. Now that'd be 3D television we can all get behind. Or in front of, depending on the viewing angle we want.
