Navigation Preview Image Filtering for Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to efficiently generate turn-by-turn direction previews that maintain user interest by filtering out irrelevant or repetitive panoramic images, leading to resource conservation and improved user experience.
Innovation Solution
A method for dynamically generating turn-by-turn direction previews by filtering panoramic images based on proximity to waypoints, relevance, and predetermined intervals, using techniques like crossfading and image jumping to transition between images, while excluding images beyond a certain distance or threshold number, and incorporating popular landmarks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all panoramic images are included in the turn-by-turn direction preview, then the completeness of the preview information is improved, but the system resource consumption increases and user interest decreases due to repetitive content
Solution Approach 1:
The patent extracts and removes redundant panoramic images from the preview sequence. By identifying and eliminating repetitive images while retaining unique visual information, the system reduces resource consumption without sacrificing the completeness of meaningful preview content.
Solution Approach 2:
The patent discards redundant images that provide no additional value to the user experience. By selectively removing repetitive content and keeping only essential images, the system optimizes resource usage while preserving the core informational value of the preview.
2Loss of information
If all panoramic images are included in the turn-by-turn direction preview, then the completeness of the preview information is improved, but the user engagement decreases due to repetitive and irrelevant content
Solution Approach 1:
The patent extracts only the essential and non-repetitive panoramic images for the preview. By removing redundant content that would bore users, the system maintains complete informational value while significantly improving user engagement and preventing disengagement.
Solution Approach 2:
The patent discards repetitive images that reduce user interest. By keeping only unique and valuable visual content, the system preserves complete route information while enhancing user engagement through a more interesting and varied preview experience.
3Loss of information
If panoramic images are filtered based on proximity to waypoints and predetermined intervals, then the relevance of displayed images is improved, but the quantity of displayed images is reduced
Solution Approach 1:
The patent applies different selection criteria to different segments of the route based on proximity to waypoints. By filtering images at specific intervals and locations of interest, the system ensures high relevance of displayed images while optimizing the quantity shown based on local requirements.

AI summary
Aspects of the present disclosure relate to generating turn-by-turn direction previews. In one aspect, one or more computing devices 110, 130, 140, 160, may receive a request for a turn-by-turn direction preview. The one or more computing devices may generate a set of turn-by-turn directions 332, 334 based on a series of road segments 1-4, 460, 462, 464, 466, 468 and 470 connecting a first geographic location A, 702 and a second geographic location B, 718. Each direction in the set of turn-by-turn directions may be associated with a corresponding waypoint 410, 420, 430, 440, 450. The one or more computing devices then identify a set of images PI, 502, 504, 506, 518, 520, 522, 602, 604, 606, 608, 610, 612, 614, 616, 618, 620, 622 corresponding the series of road segments between two adjacent waypoints of the set of turn-by-turn directions, and determine a subset of the set of images to include in the turn-by-turn direction preview. Subsequently, the one or more computing devices may generate the turn-by-turn direction preview based on at least in part on the determined subset of the set of images.
