Technical description With the help of a video camera, in front of the projection plane, I am detecting the silhouettes of the player. The player stands in front of a monotone coloured wall, the color is not of relevance. A projector displays the content from the back or from the front to the projection plane. When using front projection, the camera is adjusted underneath the projection plane so it’s not disturbed by the lights of the projector, infrared can be used as well, which makes the shape recognition superb perfect. The piece can be shown on a plasma display as well. For the sound track and the sound effects two speakers and a computer with a soundcard are needed. Minimum Hardware Requirements - 1 x computer: Intel Pentium IV 2,0 GHz equipped with standard graphic card - 1x Soundcard - 1 x cheap webcam or framegrabber and a pal cam - 1 x video projectors or plasma as display medium or a monitor (Resolution 320x240)
