Vehicle Hazard Reporting Using Driver Sight Line Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reporting technologies for vehicles often increase reporting frequency based on traffic conditions, leading to driver annoyance and potential misrecognition of critical risks.
Innovation Solution
A reporting device mounted on a vehicle that includes a recognition processing unit to detect obstacles and risk targets, a sight line monitoring unit to determine driver recognition, and a reporting control unit to selectively report risks not recognized by the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reporting frequency is increased to improve traffic safety, then more risks can be detected, but the driver becomes annoyed and may fail to recognize important risks
Solution Approach 1:
The system continuously monitors the driver's sight line position and uses this feedback to dynamically adjust reporting behavior. By detecting whether the driver is looking at the obstacle or risk target through sight line analysis, the system provides appropriate feedback signals only when necessary, avoiding unnecessary alerts that would cause annoyance while maintaining safety.
Solution Approach 2:
The reporting parameters are changed based on the driver's attention state. When the driver is not looking at the detected obstacle or risk target, the system activates reporting with specific output patterns. When the driver is already observing the hazard, reporting is suppressed. This dynamic parameter adjustment optimizes both safety and driver comfort.
2Loss of information
If the reporting frequency is increased based on traffic conditions, then more hazards can be reported, but the driver's recognition of critical risks is affected
Solution Approach 1:
The system uses sight line monitoring as feedback to determine whether reporting is necessary. By continuously tracking where the driver is looking and comparing it with the position of detected obstacles and risk targets, the system provides information only when the driver's attention is not already on the hazard, preventing information overload and misrecognition.
Solution Approach 2:
Instead of reporting all detected hazards continuously, the system applies partial action by selectively reporting only those hazards that the driver has not yet noticed. This filtered approach ensures that critical information is conveyed without overwhelming the driver with excessive alerts about already-observed conditions.

AI summary
A reporting device mounted on a vehicle, comprises: a recognition processing unit configured to recognize an obstacle existing in front of the vehicle on the basis of information detected by a front detection unit and a risk target existing at least diagonally behind the vehicle on the basis of information detected by a rear detection unit; a sight line monitoring unit configured to determine whether or not a driver recognizes the obstacle or the risk target on the basis of an overlap between a sight line of the driver acquired on the basis of a captured image of the driver and the obstacle or the risk target; and a reporting control unit configured to report the existence of the obstacle or the risk target.
