Abstract:
1. A server apparatus for a space information service comprising: an information bubble managing unit for managing bubble data in which space range information including position information in a real physical space is correlated with supply information in order to virtually register an information bubble related with said desired supply information in said real physical space; an extracting unit for extracting supply information of bubble data including retrieval object space range information based on position information on a user terminal from said information bubble managing unit; a providing unit for providing said supply information extracted by said extracting unit to said user terminal; and an information bubble movement control unit for updating at least position information of said bubble data to virtually move said information bubble in said real physical space, said information bubble movement control unit including an information bubble behavior setting unit for setting behavior data defining behavior of said information bubble in said real physical space, and an information bubble moving unit for updating position information of said bubble data on the basis of said behavior data set by said information bubble behavior setting unit to move said information bubble according to said behavior data, wherein said information bubble behavior setting unit including a random number generating unit for generating a random number with respect to position information of said bubble data as behavior data; and said information bubble moving unit including a first information bubble position updating unit for randomly updating position information of said bubble data with the random number generated by said random number generating unit to randomly move said information bubble in said real physical space.
