Stadtspielplatz 1 was supposed to be the first part of a series of games that can be played by projecting digital images on certain surfaces in the city. Therefore a projector-camera-system is used, which might one day be found in mobile devices.
The prototype was made using a Wii controller combined with a mobile projector and two infrared LEDs as reference points. The goal of the game is to collect as many particles as possible with the “digital flashlight”. The implementation was done in Adobe Flash.
Stadtspielplatz 1 is the result of a study project in 2011 dealing with new interaction patterns for mobile projectors.
