AR Radar Map Display Control via Distance-Based Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality (AR) systems, users face challenges in setting an appropriate display range for radar maps, as they often either miss important data at longer ranges or are overwhelmed by data at shorter ranges, making it difficult to understand the positions of multiple object data.
Innovation Solution
A method is implemented where a terminal calculates distances to multiple object data positions, determines an optimal display area based on their distribution, and adjusts the display range dynamically to ensure that relevant object data are easily visible on the screen, using a processor to manage the display and user input for setting preferences.

Engineering Contradiction Analysis
1Quantity of substance
If the display range is set to cover a large area, then more object data can be displayed, but the position information becomes difficult to understand and data clutter increases
Solution Approach 1:
The display range is divided into multiple concentric circular areas (first circular area, second circular area, third circular area) with different display densities. Object data in different regions are displayed with different levels of detail, allowing comprehensive coverage while maintaining clarity through regional segmentation.
Solution Approach 2:
Different display characteristics are applied to different regions of the radar map. The first circular area (closest to terminal) displays object data with higher prominence and detail, while outer areas display data with reduced detail, creating local quality variations that improve overall understandability.
2Ease of operation
If the display range is set to cover a short area, then position information is easy to understand, but important object data at longer ranges may be missed
Solution Approach 1:
The radar map is segmented into multiple concentric circular areas extending to different distances from the terminal. This segmentation allows the display to cover a large total area while maintaining manageable density in each segment, ensuring important distant data is not missed.
Solution Approach 2:
The display system dynamically adjusts the number and density of object data displayed in each circular area based on the terminal's position and the distribution of object data. This dynamic adjustment ensures comprehensive coverage of important data while adapting to maintain understandability.
3Device complexity
If fixed display range is used, then device complexity is reduced, but adaptability to different object data distributions is poor
Solution Approach 1:
The display range and density in each circular area are dynamically adjusted based on the distribution of object data and terminal position. The system automatically determines optimal display parameters for each region, providing adaptability without requiring complex manual configuration.
Solution Approach 2:
The display control mechanism automatically adapts to different object data distributions by analyzing the spatial distribution and autonomously adjusting display parameters for each circular area, eliminating the need for complex external configuration while maintaining high adaptability.

AI summary
A method of controlling display of object data includes calculating distances from a terminal to the positions of multiple items of the object data, determining, by a processor, an area based on the distribution of the calculated distances, and displaying object data associated with a position in the determined area on a screen.
