3D Navigation App Segmented Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current map-based applications, especially those using 3D maps, are often processing-intensive, leading to inefficiencies, slowness, and a lack of realism, making them less useful for navigation and other purposes.
Innovation Solution
A navigation application with a touch-sensitive screen and multi-touch interface that offers multiple views (2D and 3D turn-by-turn navigation, realistic road signs, dynamic instruction generation, voice recognition, and integration with other routing apps, along with adaptive UI controls and background navigation capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 3D maps are used in navigation applications, then visual realism and user experience are improved, but processing intensity increases导致应用变慢和效率降低
Solution Approach 1:
The patent divides the map rendering into multiple levels of detail and segments the processing tasks. Different portions of the map are rendered at different resolutions, with only critical areas rendered in high detail. This segmentation allows the application to maintain visual realism in important areas while reducing overall processing intensity and improving application efficiency.
2Illumination intensity
If 3D maps are used in navigation applications, then visual realism is improved, but battery consumption increases
Solution Approach 1:
The patent implements periodic updates of 3D map elements rather than continuous high-resolution rendering. The system dynamically adjusts the rendering frequency and detail level based on user interaction, device orientation, and navigation context. This periodic action maintains visual realism when needed while significantly reducing battery consumption during static or low-activity periods.
3Adaptability or versatility
If multiple view modes and features are integrated, then adaptability and user experience are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal control framework that manages multiple view modes (2D, 3D, hybrid), navigation features, and integration points with other routing applications through a single unified interface. This multi-functional architecture allows the system to adapt to different user needs and contexts while maintaining a consistent, simple user experience and reducing the apparent complexity through standardized controls and protocols.

AI summary
Some embodiments provide a device that stores a novel navigation application. The application in some embodiments includes a user interface (UI) that has a display area for displaying a two-dimensional (2D) navigation presentation or a three-dimensional (3D) navigation presentation. The UI includes a selectable 3D control for directing the program to transition between the 2D and 3D presentations.
