Patent ID: 8248666

Claim:
An information output device, comprising: a stage surface on which media are disposed in a state where the media are opposite to the stage surface, the media being printed with dot patterns in which a plurality of reference lattice point dots are provided within an area of a block where information dots are arranged, the plurality of reference lattice point dots defining a plurality of lattice areas each defining a respective virtual lattice point therein, wherein information represented by the information dots is defined by distances and directions of the information dots from the virtual lattice points, and a direction of the block is defined by a shape formed by a first number of the lattice areas, the first number of lattice areas being identifiable by the distance and direction that the information dot in each of the first number of lattice areas is arranged with respect to the virtual lattice point defined, in each respective lattice area of the first number of lattice areas, the dot patterns are read by an imaging unit disposed in a space below the stage, code values indicating the dot patterns and directions of the media obtained from the analyzed result of the dot patterns are calculated from photographed images obtained by the imaging unit and locations of the media disposed on the stage surface defined by XY coordinates are calculated, and information corresponding to the calculated results is outputted, wherein in the space below the stage, a projection unit is disposed, in addition to the imaging unit, and the projection unit controls images or moving pictures projected on the stage surface by calculating the code values of the dot patterns obtained from the photographed images by the imaging unit and the direction of the card obtained from the analyzed results of the dot patterns and calculating the location of the medium disposed on the stage surface defined by XY coordinates.
