Mobile Map Display Anchoring Device Position During Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map applications on mobile devices often fail to provide an optimal user experience due to the marked position of the device moving out of the displayed area, especially when users are navigating or previewing route information, leading to compromised user interaction and navigation efficiency.
Innovation Solution
A method implemented on mobile devices that calculates the average speed of the device's geographic location and adjusts the map display area accordingly, keeping the device's position fixed on the interface while updating the map to reflect changes in location, thereby ensuring the position remains visible and optimizing the display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the map displayed area is adjusted to allow users to preview route information, then the user can view more map content, but the marked position of the mobile device may move out of the displayed area
Solution Approach 1:
The patent introduces a fixed position area on the user interface that is independent of the map displayed area. The first mark (device position) is anchored in this fixed position area, while the map can be adjusted in the map displayed area. This dimensional separation allows the map to expand or shift without affecting the visibility of the device position marker.
Solution Approach 2:
The user interface is segmented into distinct functional areas: a fixed position area for displaying the device's current location marker, and a flexible map displayed area for showing route information. This segmentation allows independent control of each area, enabling the map to be adjusted for route preview while the device position remains consistently visible in its dedicated fixed area.
2Measurement precision
If the map is updated to reflect real-time location changes, then the navigation accuracy is improved, but the user experience is compromised when the position marker moves out of view
Solution Approach 1:
The patent creates a separate fixed position area that is decoupled from the map displayed area. The device position marker is anchored in this fixed area, ensuring it remains visible regardless of map updates or adjustments. This allows real-time location tracking to continue with full precision while the user experience is maintained through consistent visibility of the position marker.
Solution Approach 2:
The fixed position area acts as an intermediary element between the dynamic map content and the static device position marker. It mediates the relationship by providing a stable anchor point for the position marker that is independent of map changes, thus preserving both location tracking accuracy and user experience.
3Loss of information
If the device position is kept fixed on the interface, then the position remains visible during navigation, but the map cannot be adjusted for route preview
Solution Approach 1:
The interface is divided into a fixed position area and a flexible map displayed area. The first mark representing device position is confined to the fixed position area, ensuring visibility. The map displayed area can be independently adjusted for route preview. This segmentation resolves the contradiction by allowing both position visibility and map flexibility to coexist in their respective zones.
Solution Approach 2:
The patent introduces a separate dimensional space (fixed position area) for the position marker that is independent of the map's dimensional space. This allows the map to be adjusted in its own space for route preview while the position marker maintains its visibility in the fixed position area, effectively resolving the conflict between visibility and flexibility.

AI summary
This application is directed to a geographic information display method. While a first mobile device is executing an instant messaging application, it obtains its own geographic location information, a second mobile device's geographic location information, and a first timestamp at which the geographic location information is recorded. The first mobile device then displays an interactive map associated with the first timestamp on a user interface. The displayed map includes two marks that represent the locations of the first and second mobile devices, respectively, and instant messages exchanged between these two mobile devices are displayed on the map adjacent to the two marks. As the first mobile device obtains updated geographic location information in association with a second timestamp, it updates the location of the second mobile device while the mark corresponding to the first mobile device remains at the same location on the user interface.
