Navigation Server Topic Correlation Rules for Trip Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems lack convenience for trip planning in unfamiliar or low-visit frequency areas, as they do not provide adequate guidance or recommendations for places of interest.
Innovation Solution
A navigation server and client system that stores topics for areas and correlation rules, allowing users to designate topics and receive guide information for places corresponding to those topics in a defined order, enhancing user experience even in unfamiliar areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a navigation system uses keyword-based place search and frequency-based destination selection, then the ease of operation is improved for familiar areas, but the convenience for trip planning in unfamiliar areas deteriorates due to lack of historical data
Solution Approach 1:
The navigation server pre-calculates and stores correlation rules between different places in advance, based on statistical analysis of multiple users' navigation histories. This preliminary preparation enables the system to provide meaningful trip planning recommendations even in unfamiliar areas without requiring the current user to have historical data, thus resolving the contradiction between ease of operation and adaptability for trip planning
Solution Approach 2:
The invention introduces correlation rules as an intermediary mechanism that connects keyword-based search with trip planning functionality. These correlation rules, stored in the navigation server, act as a mediator that provides structured guidance for visiting multiple places in an area, bridging the gap between simple destination search and comprehensive trip planning, thereby improving both ease of operation and adaptability

AI summary
Provided is a navigation server or the like capable of improving a convenience for trip planning by a user of a navigation client. The user can designate, on the navi-client 2, a plurality of topics from among the plurality of topics TPX0(k) in the designated area ROI, as the primary designated topics TPX1(i) and further as the secondary designated topics TPX2(j). Then, on the navi-client 2, the guide information can be output for guiding the plurality of POI(j) corresponding to the plurality of secondary designated topics TPX2(j) in the order which is basically defined in accordance with the correlation rule among the designated topics TPX2(j).
