Mobile Terminal Navigation POI Display Along Route
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems do not efficiently display points of interest (POIs) located alongside a pre-set route without altering the route or re-searching the route, limiting user convenience.
Innovation Solution
A navigation method and apparatus for a mobile terminal that allows users to select and display POIs located alongside the current route without changing the route, using a POI search function to identify and display POIs on the roadside or near the route, utilizing a controller to manage map data and provide location information on a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the navigation system searches and displays POIs near the route, then the user can find more location information, but the system may display irrelevant POIs that are not accessible from the route
Solution Approach 1:
The patent segments POIs into two distinct categories: first POIs located by the roadside of the route (accessible) and second POIs located near the route (inaccessible). The system selectively displays only first POIs that are directly accessible from the navigation route, separating relevant information from irrelevant information. This segmentation resolves the contradiction by ensuring displayed POIs are both numerous and relevant to the user's journey.
2Ease of operation
If the system provides comprehensive POI information, then user convenience is improved, but the navigation route may be altered or re-searched
Solution Approach 1:
The patent performs preliminary identification of POIs that are located by the roadside of the predetermined navigation route before the user completes route planning. The system pre-screens and marks accessible POIs (first POIs) along the route, so when the user requests POI information, the pre-identified relevant POIs are immediately displayed without altering or re-searching the route. This preliminary action resolves the contradiction by providing comprehensive POI information while maintaining route stability.

AI summary
A navigation method and apparatus of a mobile terminal displays only a particular point of interest (POI) existing by the roadside of a pre-set route when the POI is selected by the user, to thereby provide the user-selected POI without changing the route (or without re-searching the route). The navigation apparatus of a mobile terminal includes a display unit configured to display a route from a current location to a destination on map data, and a controller configured to search a first point of interest (POI) among the first POI located by the roadside of the route and a second POI located near the route, and display location information of the searched first POI on the display unit.
