Making flat table interactive with Kinect and a projector

Microsoft Kinect is more than a game device, with the help of the embedded depth sensor, one can turn any flat table to an interactive multitouch surface. I made it yesterday. Just hang it for more than 1 meter above the table, and project your interactive content onto the table. That’s all for the hardware part.

For the software, you have to use OpenNI(or other Kinect hacks such as freenect), OpenCV to get your touch finger blobs,  this needs some programming.  You have to fire TUIO events when touches are detected to a multitouch-enabled application. That’s it. For the application, I use MT4j for a demo.
