Abstract:
1. An information providing system comprising: a portable terminal that is connected with a registration terminal for registering target information that is to be used by the portable terminal, and that provides the target information in the registration terminal to the portable terminal; and the registration terminal being adapted to associate a plurality of different pieces of the target information with a single information group, and to register the information group, which is correlated with reference position information for specifying a reference position as a reference; the target information in the registration terminal being provided to the portable terminal by automatically selecting a particular one of the different pieces of the target information from the information group on the basis of the positional relationship between the reference position that is specified by the reference position information corresponding to the information group, and the portable terminal, and by transmitting the selected target information to the portable terminal, the registration terminal including a storage device that stores the information group, which is correlated with the reference position information, in which, when portable terminal position information for specifying the position of the portable terminal is received together with a transmission request for the target information, the target information is selected from an information group in accordance with the received transmission request based on a positional relationship between the reference position that is specified by the reference position information corresponding to the information group in accordance with the received transmission request, and the position that is specified by the received portable terminal position information, and the selected target information is transmitted to the portable terminal; and the portable terminal including a position information retrieving device that retrieves the portable terminal position information in which the portable terminal position information retrieved by the position information retrieving device is transmitted to the registration terminal together with the transmission request; and the information group including first target information and second target information having more detailed content than the first target information, which are associated with each other; and the selection of the target information, the first target information being selected from the information group if a distance from the reference position that is specified by the reference position information to the position that is specified by the portable terminal position information is within a first predetermined range, and the second target information is selected from the information group if a distance from the reference position that is specified by the reference position information to the position that is specified by the portable terminal position information is within a second predetermined range which is smaller than the first predetermined range.
