Abstract
We present the development of a multi-touch display
based on computer vision techniques. The developed system
is built upon low cost, off-the-shelf hardware components
and a careful selection of computer vision techniques. The
resulting system is capable of detecting and tracking several
objects that may move freely on the surface of a wide
projection screen. It also provides additional information
regarding the detected and tracked objects, such as their
orientation, their full contour, etc. All of the above are
achieved robustly, in real time and regardless of the visual
appearance of what may be independently projected on the
projection screen. We also present indicative results from
the exploitation of the developed system in three application
scenarios and discuss directions for further research.
