Vehicle Alert System Eye Gaze Display Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle alert systems often generate unnecessary alerts when the driver is not focused on a potential danger spot, leading to missed warnings due to distraction or awareness of the situation, and lack effectiveness in guiding the driver's attention to critical areas outside the vehicle.
Innovation Solution
A vehicle alert system that determines the driver's eye gaze direction to display visual alerts on the most appropriate display, guiding their attention to potentially dangerous situations and adjusting alert generation based on criticality levels and awareness status, using a combination of external detectors and eye gaze direction analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual alert signals are generated when the driver is not focused on a danger spot, then the driver may be notified of dangerous situations, but the driver may miss the visual alert signal or be delayed looking at it due to distraction
Solution Approach 1:
The system performs preliminary action by detecting the driver's eye gaze direction in advance and predicting future gaze positions. This allows the system to prepare and display alert signals at locations where the driver is likely to look, rather than waiting for the driver to naturally shift attention to the danger area.
Solution Approach 2:
The system dynamically adapts the display location of alert signals based on the driver's real-time eye gaze movement. Instead of fixed display positions, the alert signals are continuously repositioned to track and appear at the driver's predicted gaze location, making the alert system responsive to the driver's attention dynamics.
2Device complexity
If alert signals are displayed on fixed displays, then the system is simple to implement, but the driver may not notice the alert if it is not in their field of view
Solution Approach 1:
The system transitions from static, fixed display positions to dynamic display positioning that follows the driver's eye gaze. The alert signal display location is continuously updated based on real-time eye tracking data, ensuring the alert appears in the driver's current or predicted field of view.
Solution Approach 2:
The system uses eye gaze detection as feedback to determine where to display alert signals. By continuously monitoring the driver's gaze direction and using this information to position alerts, the system creates a closed-loop feedback mechanism that adapts to the driver's attention state.
3Reliability
If alert signals are generated for all detected dangerous situations, then comprehensive safety monitoring is achieved, but unnecessary alerts are generated when the driver is already aware or has no intention of changing lane
Solution Approach 1:
The system performs preliminary assessment of driver awareness by analyzing eye gaze direction and lane change intention before generating alert signals. This preliminary check prevents unnecessary alerts from being displayed when the driver is already monitoring the situation or has legitimate reasons for their current behavior.
Solution Approach 2:
The system changes the parameter of alert generation from a binary on/off state to a conditional state based on multiple parameters including eye gaze direction, detected danger location, and inferred driver intention. This allows selective suppression of alerts when contextual parameters indicate the driver is already aware.

AI summary
The system comprises at least one external detector (21) that provides a detection information related to a potentially dangerous driving situation outside the vehicle (100), an eye gaze direction detector (22) that provides a driver eye gaze direction information, an alert unit (23) that receives the detection information and the driver eye gaze direction information, generates a visual alert signal, when a potentially dangerous driving situation is detected, and controls display of the visual alert signal (30) on a display of the vehicle, characterized in that, the vehicle (100) comprising a plurality of displays (10a-10g), the alert unit (23) selects one of said plurality of displays of the vehicle, depending on the driver eye gaze direction information, and controls display of the visual alert signal (30) on the selected display.
