Abstract: An input unit indicates a departure point and a destination point on map information. A calculation unit extracts a plurality of routes each connected from the departure point to the destination point from the map information, and calculates a guidance demand degree of arbitrary points along each of the plurality of routes. A guidance demand degree is an evaluation value of the point based on a linearity of route, a complexity of route junction, and a change of route width. A route selection unit selects one route from the plurality of routes based on the guidance demand degree of each route. A guidance generation unit generates guidance information of the point decided to guide based on the guidance demand degree along the one route. A presentation unit presents the guidance information to a user.

Abstract: There is disclosed an information exchange apparatus in which apparatus name information and address information of a display/headphone are transferred to a DVD reproduction apparatus from the display/headphone via a path of an infrared ray or the like different from a radio path for exchanging information. The information are registered in the DVD reproduction apparatus. The DVD reproduction apparatus on a transmission side transmits video and audio information based on information concerning the display/headphone as a reception side registered in the reproduction apparatus, and the display/headphone on the reception side receives the video and audio information transmitted to the display/headphone.

Abstract: A common dictionary management system that can reduce the work of data registration into dictionaries. Exchange data generated in any local dictionary of a natural language processing system is sent to the local dictionaries of other natural language processing systems automatically. A local dictionary management portion and a common dictionary management portion collect updated dictionary data from a plurality of local dictionaries and updating time information. The local dictionary management portion updates the common dictionary and the local dictionaries according to the collected dictionary data and the time information. The local dictionary management portion compares the information with the latest time on which dictionary data was distributed to the local user dictionaries with the updating time information of the dictionary data in the common dictionary to distribute the dictionary data of the common dictionary selected according to the result of the comparison, to the local dictionaries.

Abstract: A route guidance system for a pedestrian. An input unit inputs a departure point and a destination point of the pedestrian. A route data memory stores route data representing position and connection of each route comprising a road network. A route calculation unit calculates a route from the departure point to the destination point by referring to the route data in said route data memory. A landmark memory stores landmark data for the pedestrian's confirmation; a landmark represents a signpost of the departure point, the destination point, and the route. A landmark selection unit selects the landmark data corresponding to the route calculated by said route calculation unit from said landmark memory. A presentation unit presents a route guidance to the pedestrian using the calculated route and the selected landmark data.
