Abstract: A geogame utilizes wireless devices to track the movements of the players. As players move, virtual tails are generated behind each player, and their locations are determined and geocast, via a wireless geographic broadcast protocol, to all players of the geogame. Each player observes all players movements and tail locations on his/her wireless device. Players can draw sketches utilizing their respective virtual tails and/or players can traverse courses which involve various types of terrain. Players can try to avoid virtual obstacles that can be generated within the game. Players can be provided weapons to shoot through boundaries and tails.
