Cognitive-Ability-Aware Navigation Route Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to consider cognitive abilities of drivers, particularly senior drivers, leading to increased traffic accidents.
Innovation Solution
A navigation system that includes a cognitive ability assessment part, a map information database, and a route search part, which assesses and adjusts route searches based on cognitive ability levels using weighting information grouped by cognitive ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional navigation systems provide route guidance, then route search functionality is achieved, but the system does not account for driver cognitive abilities leading to reduced safety for senior drivers
Solution Approach 1:
The system performs preliminary cognitive ability assessment before route search, storing assessment results and cognitive ability level information in advance. This allows the route search to later utilize pre-prepared weighting information matched to the driver's cognitive level, eliminating the need for real-time assessment during navigation and reducing operational complexity while maintaining safety.
Solution Approach 2:
The system changes the parameters of route search by introducing cognitive ability-based weighting information that modifies how routes are evaluated. Different cognitive ability levels trigger different weighting schemes for route constituents, transforming the standard route search into a cognitively-adapted search that improves safety without requiring complete system redesign.
2Measurement precision
If the system stores detailed weighting information grouped by cognitive ability, then route search accuracy for individual drivers is improved, but map information database size increases
Solution Approach 1:
The system applies local quality by providing different weighting information for different cognitive ability levels rather than using a single universal weighting scheme. Each cognitive ability level has its own tailored weighting information that precisely matches the driver's capabilities, improving route search accuracy for each individual while maintaining a manageable database structure through organized categorization.
3Adaptability or versatility
If the system conducts cognitive ability assessment, then driving assistance is tailored to individual capabilities, but the assessment process adds time to the navigation setup
Solution Approach 1:
The cognitive ability assessment is performed in advance before the actual navigation begins, and the results are stored for future use. This preliminary action allows the system to be adaptive to individual driver capabilities while minimizing the time impact during actual navigation, as the assessment occurs once rather than repeatedly during each route search.

AI summary
Assist driving in a manner that depends on cognitive abilities. A navigation system includes a cognitive ability assessment part, a map information database, and a route search part. The cognitive ability assessment part assesses a cognitive ability of a driver relating to driving. The map information database stores map information for use in a route search. The route search part conducts the route search from a location of a vehicle to a destination location using a starting location of the route search, the destination location of the route search, and the map information.
