20090104955 | GAME DEVICE - A game device including: a first running surface; a second running surface positioned below the first running surface; a plurality of running objects which run on a track of the second running surface, each of the plurality of running objects including capturing unit for capturing an image; and a plurality of model objects which run on the first running surface following each of the plurality of running objects is provided. The game device further includes: a plurality of two-dimensional codes arranged in an information arrangement surface extending in parallel to the second running surface and capturable from the capturing units with sizes and a sequence in which one or more of the plurality of two-dimensional codes are always included in a field angle of the capturing unit of each of the plurality of running objects disposed in optional positions on the track of the second running surface; and a position detection unit for detecting positions of the plurality of running objects based on positional information recorded in the two-dimensional codes captured by the capturing unit. Thus, costs for position detection of the model objects in the game device in which the plurality of model objects run are reduced, accuracy of the position detection is enhanced, and time period required for the position detection is shortened. | 04-23-2009 |
