postheadericon Kinect + Open Drivers + Physics Engine = Piles of Kickable Corpses

I first met John Boiles in October 2009 at Dorkbot Austin, when he was an undergrad engineer at UT, and was presenting an RC car he’d hacked so that it could be driven just by tilting his iPod. He’s since graduated and gone to work for Yelp, and in that time his extracurricular projects have included a set of iPod controlled dance floor lights that synchronize with your rump-shakin’, a combination Kegerator and beer-data-logging suite, and an upgunned version of his smartphone steering system that works with a full-size automobile.

His most recent project weds Microsoft’s Kinect to Garry’s Mod, a popular sandbox game based on Valve’s Source physics engine, via PrimaSense’s recently-released OpenNI framework and some custom C++ code.

The net result is a system that recognizes your movements and allows you to interact with virtual objects using the sophisticated physics of Valve’s engine, as the embedded video demonstrates. Don’t miss the bit at 0:30 where John, in the person of a giant robomechanical avatar, kicks a pile of virtual bodies across the screen.

More details and links to source code at Yelp Engineering. [Thanks, John!]

postheadericon Interactive Mirror

Alpay Kasal, who helped create Alpha One Labs‘ Twitter-searching Christmas tree, has a new project: a touchscreen mirror.

thought to build this version of the Interactive Mirror after I saw some dielectric glass mirrors with LCD panels built into them. They’re meant to be the bathroom of the future, complete with news and weather to accompany your toothpaste in the morning. Sounds nifty, but it looked completely un-fun. It lacked a human touch. I brainstormed with friend Sam Ewen and soon started cutting aluminum t-slot.

There are some tricks built into this installation: like internal mirror bounces for greater projection throw (wide angle lenses are expensive) and a projection running at an aspect ratio of 9:16 rather than 16:9. I’m also using mouse emulation, which is key in my opinion.

postheadericon Kinect ‘x-ray’ overlays you with CT-scan imagery

The Kinect allows tracking of users without additional markers. We develop a magic mirror that generated an overlay of a video image with volume visualization from a CT volume. Such a system could be used for education of anatomy.
