Abstract

See full text

A moving object navigation apparatus includes an input section, a map information memory section, a database, a coordinate retrieval section, a route calculation section, and an output section. The input section inputs institution names indicating the present location of a moving object and a destination by using a natural language. The map information memory section stores a map including information of roads and institutions. The database stores the relationship between the institution names on the map stored in the memory and position indexes. The coordinate retrieval section retrieves the institution names indicating the present location and the destination, which are input by the input section, from the database, and outputs corresponding position indexes. The route calculation section obtains the shortest route between the position indexes of the present location and the destination, which are output from the coordinate retrieval section, by referring to the map stored in the memory. The output section outputs route information obtained by the calculation section to the user of the moving object.
