Electronic Map Edge Indicators for POI Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices with limited screen size face inconvenience in navigating and locating points of interest (POIs) outside the displayed area, requiring time-consuming operations like zooming, panning, and menu selections to view relative locations and POIs on electronic maps.
Innovation Solution
Displaying an indicating object on the edge of the map for POIs outside the displayed area, allowing users to quickly change the map view to include the POI by selecting the object, with options for sliding or switching the display and maintaining the same scale, enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the screen size is limited, then the device portability is improved, but the displayed area of the electronic map is reduced
Solution Approach 1:
The patent extends the display space from the traditional 2D screen area into a third dimension by showing indicating objects outside the map display area. These indicating objects are positioned in the peripheral region of the screen, effectively utilizing the unused screen real estate to provide additional information about POIs without requiring the user to zoom out or pan the map.
2Volume of moving object
If the displayed area is reduced, then the device portability is improved, but the operation complexity increases
Solution Approach 1:
The system pre-calculates and displays indicating objects for POIs that are outside the current map display area but within a predetermined distance. This preliminary action allows users to see available POIs and their directions without having to perform complex operations like zooming out to see them first, thereby simplifying the user interaction flow.
Solution Approach 2:
The indicating object serves as an intermediary element between the map display area and POIs outside it. Instead of requiring users to directly interact with the map (zooming, panning), the indicating object provides a simplified interface that mediates the interaction, allowing users to quickly access POI information and navigate to them with minimal operations.
3Measurement precision
If traditional navigation operations are used, then the map display accuracy is maintained, but the time consumption increases
Solution Approach 1:
The patent replaces the traditional mechanical navigation operations (zooming in/out, panning) with a more efficient information presentation system. Instead of requiring users to physically manipulate the map view through multiple steps, the system substitutes these mechanical operations with intelligent display of indicating objects that provide directional guidance and POI information, significantly reducing the time required to locate and navigate to POIs.

AI summary
A method and an apparatus for operating a displayed area of an electronic map and a recording medium are provided. In the method, a displayed area of an electronic map is displayed first. Then, an indicating object of a point of interest (POI) located outside the displayed area is displayed on an edge of the displayed area towards a direction of the POI with respect to the displayed area. When the indicating object of the POI is selected, the displayed area of the electronic map is changed to the displayed area comprising the POI. Accordingly, users are able to quickly change the displayed area and check a location and related information of each POI in a simple operation manner.
