Landmark update system and navigation device
First Claim
1. A landmark update system for updating landmark information to be displayed together with a route for route guidance, said system comprising:
- a navigation device operable to perform route guidance through the use of landmark information which is determined as the latest based on incoming landmark information over a first communication line, to increment a counter of a number of times a landmark is displayed, to calculate points based on a level of interaction between a user and the landmark, and to generate cumulative information from at least the incremented counter and the calculated points;
a landmark server operable to communicate with said navigation device through communications over the first communication line, and to offer the latest landmark information which is registered; and
a retailer terminal operable to register the latest landmark information to said landmark server by communicating with said landmark server over a second communication line, wherein said navigation device is operable to transfer said generated cumulative information to said landmark server over the first communication line, and wherein, based on the cumulative information transferred over the first communication line and information about the navigation device from which the cumulative information is transferred, said landmark server is further operable to generate compilation data obtained by subjecting the cumulative information to a compilation process, and to transfer the compilation data to a corresponding retailer terminal over the second communication line.

Abstract
The present landmark update system enables route guidance through the use of landmark information which remains always the latest for route guidance, and operates as follows: a navigation device 1 communicates with a landmark server 30 so as to receive to-be-updated landmark information 1001 for guiding the user by utilizing landmarks. Information about any landmark displayed is transferred to the landmark server 30 as cumulative information 1002. The landmark server 30 manages the cumulative information 1002 so that compilation data 1003 is generated for transfer to a retailer terminal 40 corresponding to the displayed landmark(s). The retailer terminal 40 refers to the compilation data 1003 so as to generate landmark information which is considered optimum, and transfers it to the landmark server 30 as registering landmark information 1004.
