Motion and AR games read the body, hands or face and place a player inside a game on a screen or wall. Cameras and sensors track movement, so players need no controller. Event organisers, malls, brand teams and exhibition builders buy them for queues, launches and festive campaigns. To choose, check the sensor range and the space the player needs, how many people play at once, and whether a custom brand skin or theme is needed. Photo-style products suit events, while game-style products suit venues where people stay and play.
