Zero Geography reports on a real-time game using GPS devices which has – for our purposes, interesting applications for coordinating SAR or other response efforts. From Zero Geography: GPS Real-World Gaming in Hybrid Space.

A real-time, multiplayer, GPS game for mobiles is being played out in the real-world. The game, played by groups of four or five people, uses a one kilometer radius around any point on Earth to delineate spatial extents in which three or four chasers try to capture one runner. Each one of the players is tracked via a GPS phone and their coordinates are mashed onto a map that they can all see. The only twist that that the runner is always allowed to view the map, whilst the chasers only have access to the map every six minutes. The game is a fascinating way to roll elements of the physical and virtual together into an adrenaline-pumped experience.
