Navigation Device 3D Map Pattern Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices often struggle to effectively convey route information to users, as 2D and 3D visual displays can be confusing due to overlay with other images, making it difficult for users to match displayed information with real-world scenarios during travel.
Innovation Solution
A navigation device method that determines if map information includes designated patterns, enhances these patterns, and displays them in three dimensions on an integrated input and display device, improving user understanding by emphasizing features like building outlines and water edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If map information is displayed in 2D or 3D views, then visual information is provided to the user, but the display becomes flat and hides route details due to overlay with other images
Solution Approach 1:
The patent applies partial action by selectively enhancing only specific designated patterns (such as route markers, building outlines, and water edges) rather than enhancing all map elements. This selective enhancement approach prevents information overload while ensuring critical route details remain visible and distinguishable from other map features, thus resolving the contradiction between providing comprehensive visual information and maintaining clarity of route details
Solution Approach 2:
The patent implements local quality by applying different enhancement treatments to different regions and elements of the map display. Specifically, designated patterns related to route information receive enhanced visualization (such as increased contrast, brightness, or dimensional emphasis), while other map elements maintain their original appearance. This localized enhancement ensures that route details are prominently displayed without making the entire display overly complex
2Loss of information
If map information is displayed in three dimensions, then user comprehension is improved, but the display may still feel flat and remove the user from a feeling of reality
Solution Approach 1:
The patent utilizes color changes and variations as a key mechanism to enhance the realism of 3D map displays. By applying different colors, shades, and contrast levels to designated patterns (such as using distinct colors for route markers, building outlines, and water edges), the display creates visual depth and differentiation that enhances both comprehension and the feeling of reality. This color-based enhancement allows users to distinguish between different map elements more effectively in three-dimensional space
Solution Approach 2:
The patent applies dimensionality change by transitioning from flat 2D representations to enhanced 3D visualizations of map elements. Specifically, designated patterns are rendered with three-dimensional characteristics such as extruded building outlines, elevated route markers, and depth-coded water edges. This dimensional transformation improves user comprehension of spatial relationships while maintaining a sense of reality through realistic perspective and depth cues
3Ease of operation
If visual information is enhanced to improve user perception, then route information becomes more relatable to real-world situations, but the processing complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-identifying and marking designated patterns in the map data before rendering. The system scans map information in advance, identifies features that require enhancement (such as route markers, buildings, and water bodies), and applies enhancement flags to these elements. This pre-processing approach allows the main rendering pipeline to efficiently apply enhancements without significant additional processing complexity during real-time display operations
Solution Approach 2:
The patent utilizes parameter changes to control the enhancement of designated patterns. By adjusting rendering parameters such as contrast, brightness, size, and dimensional properties specifically for marked elements, the system enhances user perception of route information without fundamentally changing the overall rendering architecture. This parameter-based approach allows for flexible enhancement while maintaining efficient processing through existing rendering engines
