Abstract
A computer implemented method for performing route guidance using text includes obtaining an optimal route that connects a start point and an end point of a route input by a user; comparing a route history stored in a memory with the optimal route and extracting a route portion from the optimal route, the route portion being replaceable by a route portion in the route history; creating route guidance for the route portion extracted from the optimal route by using a text indication known to the user, the known text indication specifying the replaceable route portion in the route history; and creating route guidance for a route portion in the optimal route, the route portion being not replaceable by a route portion in the route history, by using a new text indication that specifies the route portion that is not replaceable.
