Wireless real-space gaming -- NetAttack

BoingBoing reader Roland Piquepaille says:
When you play a computer game, you interact with what is on your monitor, even if you're outside playing on a mobile phone. You don't interact with your physical environment. Now, computer scientists from Fraunhofer FIT want you to play outside, sharing the outdoor experience offered by children's games. NetAttack "is a new type of indoor/outdoor Augmented Reality game that makes the actual physical environment an inherent part of the game itself." In this game, two teams are fighting to destroy the central database of a virtual big company. Both teams have indoor players, who control the game from their laptop computers, and outdoor players, equipped with GPS receivers, trackers, sensors and video cameras.
