A human version of the classic arcade game Pacman, superimposing the virtual 3D game world on to city streets and buildings, is being developed by researchers at Singapore.
Players equipped with a wearable computer, headset and goggles can physically enter a real world game space by choosing to play the role of Pacman or one of the Ghosts.
A central computer system keeps track of all their movements with the aid of GPS receivers and a wireless local area network.
Merging different technologies such as GPS, Bluetooth, virtual reality, wi-fi, infrared and sensing mechanisms, the augmented reality game allows gamers to play in a digitally-enhanced maze-like version of the real world.
