Navigation Map Display Adaptation for Dynamic Guide Situations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack the ability to dynamically adjust their map display modes based on varying guide situations, such as road attributes, conditions, and vehicle states, leading to suboptimal user guidance and recognition.
Innovation Solution
A device and method that identify guide situations and adjust display parameters like rotation angle, elevation angle, and additional screen display to provide suitable map display modes, including rotation view, bird view, and driver's view, based on specific navigation scenarios like turns, highways, departures, and uphill roads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed map display mode is used in navigation systems, then the device complexity is reduced, but the adaptability to different guide situations deteriorates
Solution Approach 1:
The patent implements dynamic map display modes that automatically adjust based on the vehicle's current guide situation. The system transitions between different display configurations (e.g., 2D map, 3D building view, route guidance view) depending on factors such as road type, traffic conditions, and navigation phase, making the display adaptive rather than fixed.
Solution Approach 2:
The system changes display parameters such as map scale, orientation, dimensionality (2D/3D), and information density based on the identified guide situation. For example, it adjusts the map scale to show more detail during turns versus straight sections, and switches between top-down and angled views based on the navigation context.
2Ease of operation
If the map display is simplified for easy operation, then the ease of operation is improved, but the information completeness deteriorates
Solution Approach 1:
The patent applies different display characteristics to different regions of the map based on their importance. Critical areas such as upcoming turns, intersections, or points of interest are displayed with enhanced visual properties (e.g., larger scale, different coloring, 3D building views) while less critical areas maintain a simplified overview, thus preserving important information without overwhelming the user.
Solution Approach 2:
The map display is segmented into multiple zones with different levels of detail and information density. The foreground area near the vehicle shows detailed navigation information, while the background shows a broader context view, allowing users to easily interpret immediate navigation needs while retaining awareness of the overall route.
3Loss of information
If the map display shows detailed information for all situations, then the information completeness is improved, but the ease of operation deteriorates
Solution Approach 1:
The system applies the principle of partial action by selectively displaying detailed information only when and where it is needed for navigation. Instead of showing maximum detail uniformly across the entire map, it provides enhanced information locally at critical navigation points while maintaining a simplified view elsewhere, reducing cognitive load while preserving necessary information.

AI summary
The present invention relates to a device and method for displaying a map according to the guiding of a navigation system. The device for displaying a map may include: a situation-identifying unit for identifying a situation requiring guiding through a map screen of a navigation system; a control parameter setting unit for setting, according to the identified situation, a control parameter that is a display requirement for the map screen; and a map indication control unit for indicating the map screen in a display mode that has applied the control parameter.
