Abstract: When a navigation script has a contradiction with respect to time and place, a navigation information presenting apparatus adjusts the contradiction, executes instructions of the navigation script corresponding to restriction information, and presents the navigation information to the user. In addition, the navigation information presenting apparatus presents navigation information to the user at a timing corresponding to information representing traveling speed and/or time step.

Abstract: A navigation script includes time and point information for navigation and information for guidance, and describes an instruction sequence which can represent these information in time series in a mark-up language. According to the structured data generated from the navigation script, an instruction corresponding to a current time or point is executed, so that information for guidance to be presented is output.

Abstract: In a system for posting an advertisement via a network, the cost of the advertisement is set in consideration of a region and location or a time slot and season in which the advertisement is posted; i.e., effectiveness of the advertisement. An advertisement-cost calculation unit calculates the cost of the advertisement in consideration of a geographical factor and/or a temporal factor. An advertisement posting unit posts the advertisement on a display apparatus of an information terminal in a manner related to the geographical factor and/or the temporal factor. The advertisement-cost calculation unit may calculate the cost of the advertisement in consideration of the status of use of the advertisement obtained by a state-of-use acquiring unit and/or user information of the advertisement obtained by a user-information designating/acquiring unit. If necessary, a map display unit displays a map on the display apparatus together with the advertisement.

Abstract: In the dialog interface apparatus of the present invention, input speech is converted to an input semantic representation by a speech recognition unit, and a dialog management unit outputs an output semantic representation that corresponds to the input semantic representation, based on the input semantic representation obtained by the speech recognition unit. Having received the output semantic representation from the dialog management unit, a speech synthesis unit converts the output semantic representation to output speech identifying a specific dialog target and outputs the output speech. Further, the dialog management unit outputs to an innate operation execution unit an innate operation command that corresponds to the input semantic representation. The innate operation execution unit receives the innate operation command from the dialog management unit and executes an operation corresponding to the innate operation command.

Abstract: A service database stores a set of area information and a service program for each individual service. When position information of a mobile station and service selection information are received, the service database is searched to retrieve a service program specified by the service selection information and corresponding area information. When the mobile station is present in the area represented by the area information, the service program is executed to provide a service to the mobile station.

Abstract: An information presenting device obtains information from a variety of information sources and adjusts the amount of information to be presented to a user to a unit period acquisition information amount. The information presenting device also adjusts presenting timing based on a user's behavior and presents the adjusted amount of information to a user at the adjusted timing.

Abstract: A regular menu item arrangement is made available to a user by providing a hierarchy menu including a layer from which an object is selected and a layer from which a predicate is selected, leading to an improvement in operability. The layer of the object menu and layer of the predicate menu may be respectively made higher and lower in a hierarchy, or vice versa. Both of the menus may be switched.

Abstract: The mobile object data storage unit of the management center manages and stores the positional information and the attribute information about a number of unspecified mobile objects such as persons, creatures, objects, etc. moving outdoors, etc. Upon receipt of the detection condition of the position and the attribute of another mobile object from the terminal unit, the retrieval unit searches the mobile object data storage unit, and displays a list of corresponding mobile objects on the requesting terminal unit. The guiding information computation unit computes the guiding information to a detected mobile object selected by the requesting mobile object terminal unit depending on a predetermined privacy setting level, and transmits the guiding information to the requesting mobile object terminal unit.
