Abstract: Photogeist is a mixed-reality computer game, one which permits (and in fact, encourages) players to physically move as they play. In Photogeist you, the player, assume the role of an amateur paranormal researcher. Using your hand-held camera, your goal is to take photos of the virtual ghosts you see floating before you. The photos you take are scored based on the quality of their composition, and its up to you to take the best photos you can! Unfortunately, it's not as simple as it seems; your ghostly subjects are notoriously camera-shy, and they will do whatever they can to evade your lens. A good player will act fast, and maneuver around the ghosts to line up the best shots.
