Last time I was using a single YEI 3-Space Sensor to make a Maze and color matching game this time I wanted to try something bigger.
Using now 17 wireless sensors a whole body can be animated in real-time.
This was demoed earlier this year at the Sensors Expo in Chicago, It was much more fun to have a fully rigged model moving in real-time than a skeleton to show the sensor capabilities.

As this system is inertial it does not need line of sight with camera to work so occlusion is a non-issue. As long as the sensors are in range of the wireless dongles it could be in an adjacent room. Or start in one room and walk into another. I really really want a quality wireless HMD to play with.
I'm not much of an artist so as you can see it uses the Sinbad model and the bsp demo map. I really want to expand this and make it more into a game if I get spare time.
