Driver Gaze-Based Traffic Light Confirmation for Assistance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to accurately determine a driver's state before irritation manifests in vehicle behavior, posing safety risks.
Innovation Solution
A driving assistance device that detects a driver's gaze direction and confirmation status at traffic lights while the vehicle is stopped, adjusting assistance levels based on gaze frequency, duration, and other factors to prevent reckless driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assistance level is adjusted based on vehicle behavior, then safety response is triggered, but driver state detection is delayed until irritation manifests
Solution Approach 1:
The system performs preliminary detection of driver state by monitoring gaze direction and confirmation status before irritation manifests in vehicle behavior. The processor detects gaze direction toward traffic lights and determines confirmation status, enabling early intervention before reckless driving occurs.
Solution Approach 2:
The system transitions from monitoring only vehicle behavior (one dimension) to monitoring both gaze direction and vehicle behavior (multiple dimensions). This dimensional expansion enables detection of driver state earlier, resolving the contradiction between timely safety response and detection delay.
2Measurement precision
If gaze direction monitoring is implemented, then driver state detection is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions using the same hardware components: it detects gaze direction, determines confirmation status, and adjusts driving assistance levels. This multi-functionality improves measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The system uses existing vehicle sensors and processors to perform gaze direction monitoring, making the existing infrastructure serve multiple purposes including driver state detection, thereby limiting the increase in device complexity.

AI summary
A driving assistance device includes: a processor configured to: detect a gaze direction of a driver of a vehicle, determine a confirmation status for a traffic light around the vehicle by the driver while the vehicle is stopped, based on a movement of the gaze direction, and change an application level of driving assistance to the driver based on the confirmation status.
