Position Trajectory Display Control for Small Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with small display screens, such as mobile devices, face difficulties in displaying easy-to-read maps due to limited space, making it challenging to effectively show positioning unit trajectories without overwhelming the user with unnecessary information.
Innovation Solution
An information processing device that calculates and stores positions, displaying relevant information items with controlled distances and staggered arrangements based on distance and time intervals, allowing for a user-friendly representation of positioning unit trajectories without the need for a map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a map is displayed to show positioning trajectory, then the trajectory information is complete and accurate, but the display becomes cluttered and hard to read on small screens
Solution Approach 1:
The patent extracts only the essential trajectory position information from the complete map data, displaying selected position points along the trajectory path without showing the full map. This extraction approach maintains trajectory completeness while eliminating map-related clutter, directly resolving the contradiction between information completeness and display readability on small screens.
Solution Approach 2:
The trajectory is segmented into discrete position points that are displayed individually rather than as a continuous map overlay. Each position point is represented by information indicating its location, and the distance between adjacent points is controlled to optimize readability. This segmentation allows the system to preserve trajectory information while presenting it in a clean, readable format suitable for small displays.
2Loss of information
If all positioning positions are displayed, then the trajectory information is complete, but the display becomes cluttered and unnecessary information is shown
Solution Approach 1:
The patent applies local quality by displaying position information with varying prominence based on local characteristics. Adjacent position points that are close together are displayed with controlled spacing to prevent clutter, while maintaining the complete trajectory sequence. This selective display approach ensures trajectory completeness while reducing information density in areas where positions are closely spaced.
Solution Approach 2:
The system displays all trajectory positions (excessive action) but controls their visual presentation through distance regulation between adjacent information items. By managing the spatial arrangement and spacing of position indicators, the system maintains complete trajectory information while preventing display clutter, effectively resolving the contradiction between information completeness and visual density.
3Manufacturing precision
If the distance between adjacent position indicators is small to show detailed trajectory, then the trajectory path is clearly visible, but the information items become crowded and hard to distinguish
Solution Approach 1:
The patent implements dynamic spacing between adjacent position information items based on the actual distance between corresponding geographic positions. When positions are close together, the display distance between information items is controlled to maintain distinguishability. This dynamic adjustment preserves trajectory path accuracy while ensuring that information items remain clearly distinguishable on the display.
Solution Approach 2:
The system changes the display parameter (distance between adjacent information items) based on the geographic distance between corresponding positions. By adjusting this display parameter dynamically, the system maintains accurate trajectory representation while preventing information item crowding, thus resolving the contradiction between path accuracy and item distinguishability.
