A system having a relative coordinate input unit for inputting relative coordinates of an object to a viewer point, a data storage unit for storing plural pieces of data of attribute information (audio information, video information, etc.) of the object according to plural sets of relative coordinates corresponding to the viewer point, and a data preparing unit for reading out and delivering the data of attribute information on the object corresponding to the relative coordinates according to the inputted relative coordinates, in which the attribute information given by the object to the viewer point corresponding to the relative position of the object to the viewer point is presented in real time if the object moves very fast. The data preparing unit, when receiving the relative coordinates of the object to the viewer point from the relative coordinate input unit, converts the inputted relative coordinates into an address showing a region in which the data of the corresponding attribute information is stored, delivers the address to the data storage unit, and reads out the data of desired attribute information according to the input relative coordinates. |
