I'll be working on an open source implementation of Lilian Prerez' Frontera project at the NIMK.
Frontera is a touch-screen that projects a pre-recorded video of a player touching the screen at the same position as the user. I'm going to do the whole installation (hand-detection, recording and playback) from-scratch together with Arjan Scherpenisse. the sources will be on sourceforge. - stay tuned.
