tbeta is a new tool established by the NUI group Community. tbeta acts as an picture processing layer to take in picture data as well as output tracking data for multitouch applications. Whether FTIR or DI, scratch developed multitouch systems produce IR video streams that requirement to be processed to discover fingertips. tbeta can take this or any type of arbitrary video stream as well as run it with a series of filters to produce the touch data. This data is sent as OSC TUIO, a common protocol for touch events. together with the video camera as well as input switcher, tbeta likewise helps in system calibration. I works on Windows, OSX, as well as Linux. have a look at the getting started guide for a much better concept of exactly how it works.
