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.

The Human Pacman was developed by Adrian David Cheok and his team at the Mixed Reality Lab, National University of Singapore.

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.

It has been selected as one of the world's top 100 high-impact and visionary technologies and will showcased at the Wired NextFest 2005 in Chicago, US, which runs from June 24 to 26.
