Hallucinant, le tout avec du materiel classique...

[b]Description:[/b]
A software for camera-projector interaction was developed by Juan Roldan, Ushakiran Soutapalli, Julien Faucher, and Jan Wedekind at the Microsystem & Machine Vision Laboratory (MMVL) at Sheffield Hallam University, UK.
The software makes use of a low cost off-the shelf webcam that is calibrated against a standard projector screen. The webcam is used to determine the position of physical pointer (e.g. a pen) which is then used to virtually move the X11 pointer. Point-and-click functionality has also been implemented.
The vision system uses the Mimas real-time computer vision toolkit developed by the MMVL.
The wizard allows you to take a reference picture showing the pointer. You then have to select the region in the image for generating a reference histogram. If you are using a projector, make sure that the desktop has a bright background. Otherwise the pointer will be illuminated differently and it will not be recognized any more.
Note that thanks to Víctor Fernández there is an RPM package for openSuSE 10.2 at [url]http://www.polinux.upv.es/~vfernandez/opensuse/10.2/repodata/repoview/mando-0-1.0-1polinux.html[/url]
