SURFACE TRACKER
The Surface Tracker is an open source application for low latency multi-touch finger tracking.
It was designed initially for our Multi-Touch Everywhere system (MUTE), but it should be working more generally as well to track fingers which have been illuminated using the
laser light plane
method. It only supports low latency OptiTrack cameras;
these cameras have frame rates up to 100 frames per second, but due to their onboard image processing,
these cameras only consume 3-5% of your computer's CPU (depending on your processor).
The Surface Tracker is a standalone application, which sends Open Sound Control
messages to any connected client application at a user defineable IP address and port. It implements the
TUIO protocol,
which was specially designed for transmitting multi-touch events on a table surface.
The Surface Tracker is currently only available on Windows. This is due to the fact that the driver for
OptiTrack camera's is currently only available on Windows. We are, however, currently having discussions with
the makers of the OptiTrack camera about extending support of their cameras to OS-X.
