Apparently you can shake a Kinect to make its field of view overlap with other kinects. More kinetics would make this already mind-blowing demo even more mind blowing, and allow more people in the room (and perhaps open up cross calibration) http://www.precisionmicrodrives.com/tech-blog/2012/08/28/using-vibration-motors-with-microsoft-kinect http://www.precisionmicrodrives.com/tech-blog/2012/08/28/usi...

Now that is what I call a clever hack.

Now that's a sweet hack indeed, thanks for the link :)

Thats for the generation 1 Kinects though, which project a dot pattern and calculate distances from the dot offset. Since the camera and projector are in the same housing, they will shake synchronously, and only the dot pattern that is projected by that kinect will show up clearly on it's camera image. As far as i know the new kinects use Time of Flight technology though (which is the reason they bought PrimeSense), which sends out short pulses of light, and times when they arrive back. Since there is no dot pattern to blur, the shaking technique won't work to my knowledge.

  >which is the reason they bought PrimeSense Nope. MS licensed first gen Kinect technology from PrimeSense. Apple is the company acquired it. The ToF Kinect was developed fully in house. Here's the published paper on the depth sensor in ISSCC2013: [A 512×424 CMOS 3D Time-of-Flight image sensor with multi-frequency photo-demodulation up to 130MHz and 2GS/s ADC] http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6757370&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel7%2F6747109%2F6757318%2F06757370.pdf%3Farnumber%3D6757370 http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=675737...

    Oops, thanks for correcting me on that point. I only remembered that there was some kind of Kinect related aquisition (i think the was an article a couple of months back), but it was late at night yesterday, and I was way to tired to look up the article.
