What if virtual reality and seamless three-dimensional interfaces arrived, and they turned out to be a lot simpler technologically than you imagined? Well, perhaps you know a technology is within reach when it can not only be implemented, but implemented in a way that’s elegant and lightweight.
The latest in the ongoing YouTube-able head-tracking and 3D-manipulation videos is this creation by Timo Fleisch at the Center of Technology and Art Berlin. He has lots of resources on XNA programming, as well; thanks to a C# library, XNA and Wii mix nicely on the PC. (Less so on the Xbox 360 for obvious reasons, but XNA makes a lovely development framework for 3D on the PC, not just the console.)

The idea is pretty easy to grasp:
- 2 Wii remotes, basically acting as simple near-infrared-spectrum tracking cameras (which means, in fact, you could substitute something else if you really wanted)
- Head tracking, via emitters on glasses, as first widely popularized in a Wii video by Carnegie Mellon’s Johnny Lee
- Polarized 3D glasses, for 3D perception (and Coraline fans, natch)
- A 4-LED “LED Beacon” which allows three-dimensional manipulation of objects on the screen.
As a performance or interaction interface, I actually find the head tracking to be a bit awkward, especially as you’re still looking at a flat screen. But I love the manipulation via the “beacon.” I think there’s a lot that can be done to make manipulation of 3D spaces and objects more intuitive and more gestural – and naturally, that could lead to some lovely 3D performance tools, too (not to mention making modeling 3D objects less of a pain).
Stay tuned, same VR time, same VR channel.
Found via Veronica Pejril on Twitter.
you got one dot too mutch at the and of the vrhome.de link.
so thats why its not working i think
Reminds me of the apocryphal story that the head-tracking missile targeting system on the Mig 29 used infrared sensors on the pilot's helmet where the sensors were originally intended for TV remote controls.
nice idea, i think the system is abit too fragile (ie turning the 'beacon' upside down or turning your head away from screen.
I love the naked perfboard with LEDs for the object track. <3 Prototyping.
Found another way to do DIY head-tracking using a Gyration Air Mouse. These folks seem to have solved some of the drift and accuracy problems: VRtifacts.com
