Dynamic Map View Mode Head Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital map viewing technologies require users to navigate and zoom to inspect finer details, which can be cumbersome and limit the ability to view additional information without changing the map's layout.
Innovation Solution
The implementation of a dynamic view mode that allows users to access enhanced map details without zooming, by selectively labeling features, increasing text sizes, and providing additional information, such as 3D building models, traffic, and indoor maps, through gestures and head tracking, while maintaining the same map tiles and zoom level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users manually navigate and zoom to inspect finer details, then detailed information becomes visible, but the operation becomes cumbersome and the map layout changes
Solution Approach 1:
The patent replaces manual navigation and zooming operations with head tracking technology. The system detects head movements and automatically adjusts the map view to follow the user's line of sight, eliminating the need for manual panning and zooming while maintaining detailed information visibility.
Solution Approach 2:
The map view dynamically adjusts based on real-time head position detection. The system continuously monitors head movements and automatically repositions and resizes map features to keep the user's focal point centered and appropriately scaled, creating a dynamic viewing experience without manual intervention.
2Measurement precision
If users increase zoom level to view finer details, then readability improves, but the map layout changes and other regions become less visible
Solution Approach 1:
The system dynamically adjusts text sizes and feature scales based on the user's head position and focal point. When the user focuses on a particular area, that region's text and features are enlarged for readability, while other regions maintain their original scale, allowing multiple areas to be visible at different levels of detail simultaneously.
Solution Approach 2:
Different regions of the map have different levels of detail and text sizes based on user attention. The system applies local quality enhancement to the focal area while maintaining standard quality elsewhere, allowing readable text in the user's line of sight without sacrificing the overall map context.
3Loss of information
If additional information is provided through enhanced labeling, then information completeness improves, but the map becomes cluttered and harder to read
Solution Approach 1:
The system dynamically controls the visibility and density of map labels based on user focus. When the user's head indicates interest in a particular area, additional labels and information are revealed in that region. In other areas, labels are reduced or hidden, preventing clutter while maintaining information completeness in the focal area.
Solution Approach 2:
The system applies labeling selectively rather than uniformly across the entire map. Additional information and enhanced labeling are applied only to regions where the user's head position indicates interest, providing partial action that avoids overall clutter while delivering complete information where needed.
Data Source
AI summary
A computing device can present a map of a geographic region. The computing device can determine that a user operating the computing device has performed a particular action. The particular action can be, for example, a particular gesture. The computing device can determine that a distance between the user's face and the display screen of the computing device is within a threshold distance. If the user's face is within a threshold distance of the display screen, the map can be displayed in a dynamic view mode. While in the dynamic view mode, the map for the geographic region includes at least one additional map label for a feature that is located in the geographic region and navigation of the rendered map is disabled.
