Navigation System Using Visual Landmarks for Wayfinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle navigation systems provide directions based on distances and street names, which can be confusing if street names are not clearly marked, increasing the likelihood of users turning onto the wrong street.
Innovation Solution
A navigation system that generates and outputs natural language directions using contextual information, such as image data from cameras, traffic information, and accident reports, to provide descriptive instructions like 'turn right after the yellow truck' or 'keep left following the red car', and offers alternative routes when encountering heavy traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional navigation systems provide directions based on distances and street names, then the system is simple to operate, but the directions become confusing when street names are not clearly marked
Solution Approach 1:
The patent introduces visual context (landmarks, objects, environmental features) as an intermediary between the navigation system and the driver. Instead of relying solely on street names, the system uses recognizable visual elements in the environment as reference points, making directions more reliable when street signage is poor or unavailable.
Solution Approach 2:
The system performs preliminary analysis of the route to identify key landmarks, visual features, and potential problem areas before providing directions. By pre-processing route information to extract visually distinguishable features, the system prepares context-aware guidance that anticipates where traditional street name references may fail.
2Device complexity
If navigation systems use only distance and street name information, then the device complexity is low, but the user experience deteriorates when contextual information is needed
Solution Approach 1:
The system selectively applies contextual analysis only to specific segments of the route where it is most beneficial, rather than processing all route information equally. This partial application of complex processing maintains simplicity in areas where basic directions suffice while enhancing clarity only where contextual information provides value.
Solution Approach 2:
The navigation system applies different levels of directional detail to different segments of the route based on local characteristics. In areas with clear street signage, simple distance and name-based directions are used. In areas with poor signage or complex intersections, the system locally enhances directions with visual landmarks and contextual descriptors.
3Reliability
If navigation systems provide detailed contextual directions, then the reliability of navigation improves, but the loss of time in processing and outputting information increases
Solution Approach 1:
The system performs contextual analysis and landmark identification in advance during route planning, storing processed visual context information for quick retrieval during navigation. This preliminary processing eliminates the need for real-time analysis during driving, maintaining high reliability while minimizing time loss during actual navigation.
Solution Approach 2:
The system creates simplified copies or representations of complex route information in multiple formats (visual landmarks, audio descriptors, text descriptions) during the planning phase. These pre-generated copies can be quickly deployed during navigation without requiring complex real-time processing, thus maintaining accuracy while reducing time loss.

AI summary
Navigation systems and associated methods for providing navigation services are provided. Information associated with a desired route for a vehicle, such as a route between a current location and a desired destination, may be determined. Additionally, contextual information associated with the vehicle may be identified. Based upon the desired route and the contextual information, a direction may be generated for presentation to one or more users, and the generated direction may be output for presentation.
