Route Guide System Using POI State Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current route guide systems do not consider dynamic state information of points of interest (POIs), such as operating hours or service availability, which limits their ability to provide users with relevant navigation guidance, especially for POIs like hospitals that may have varying service hours.
Innovation Solution
A method and system that collect and analyze dynamic state information of POIs, storing it in a database and applying this information to route guidance, allowing users to receive real-time updates on POI conditions, such as operating hours, service availability, and other relevant details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only static information (name and location) of POIs is provided, then the system complexity is low, but the usefulness and reliability of route guidance deteriorates
Solution Approach 1:
The system collects and stores state information of POIs in advance in a database before actual navigation queries. This preliminary data preparation enables the system to quickly retrieve and apply relevant state information during route guidance without adding complex real-time processing, thereby improving reliability while maintaining manageable system complexity.
Solution Approach 2:
The patent extracts only the necessary state information (such as operating hours, service availability) from POI data and stores it separately in a dedicated database. This extraction approach allows the system to use only relevant dynamic information for route guidance decisions without processing the entire POI dataset, balancing reliability improvement with system complexity control.
2Adaptability or versatility
If dynamic state information of POIs is collected and applied to route guidance, then the usefulness and relevance of navigation services is improved, but the information processing complexity increases
Solution Approach 1:
State information of POIs is collected and stored in a database in advance, before actual navigation queries are made. This preliminary data preparation allows the system to quickly retrieve and apply relevant state information during route guidance without adding complex real-time processing requirements.
Solution Approach 2:
A dedicated state information database is introduced as an intermediary component between POI data sources and the route guidance system. This database stores pre-processed state information, simplifying the information processing task of the route guidance system while enabling versatile navigation services that consider dynamic POI states.
3Measurement precision
If state information database is implemented to store dynamic POI information, then the information accuracy is improved, but the data storage requirements increase
Solution Approach 1:
The system extracts and stores only the essential state information (such as operating hours, service availability status) from complete POI datasets. This selective extraction maintains high information accuracy for navigation decisions while minimizing data storage requirements by excluding unnecessary detailed information.
Solution Approach 2:
The state information database stores detailed state information only for POIs that are relevant to current or potential navigation queries. This localized data storage approach ensures high information accuracy for needed POIs while reducing overall storage requirements by not maintaining complete information for all possible POIs.

AI summary
A route guide method includes collecting state information of respective points of interest (POIs) and storing the collected state information in a state information database, extracting state information of one or more candidate POIs with reference to the state information database according to a request for the state information of the one or more candidate POIs, and applying the extracted state information of the candidate POIs to routes to the respective POIs to guide a user along the routes to the respective candidate POIs.
