First Claim
Patent Images
1. A route guide method comprising:
- collecting state information of respective points of interest (POIs) and storing the collected state information in a state information database;
searching a plurality of candidate POIs stored in the state information database;
extracting state information from each of the plurality of candidate POIs;
analyzing the state information;
determining whether each candidate POI is a valid POI based on the state information;
sending information for each valid POI to a navigation device;
providing an option to select a current time, an arrival time, or an after service time as a reference time;
checking whether the reference time is the current time, the arrival time, or the service time; and
calculating a time required value for each of the respective candidate POIs based on the reference time,wherein the after service time is based on a time for receiving services at an associated POI, andwherein the state information is information on a dynamic state of the POI.
