Abstract
Position data and spot data of explanation contents are stored in a spot data database in a center. Preference data of the individual users are stored in a preference data database. Group's preference data of user groups are stored in group's preference data database in the center. When the center extracts each user's present time and present position from data received from the user, it selects spot data on the basis of the user's resent time and present position and also preference data and user group's preference data obtained with user ID from the preference data database and the user group's preference data database, and instructs transmission of the selected spot data to the pertinent user's portable data terminal. Thus, it is possible to provide apt data to users even when the users take action patterns different from a usual action pattern.
