Steering Wheel Display Visibility via Driver Gaze Tracking
Solution Overview
Problem
In vehicle operation systems, when a driver's posture changes during driving, especially at high speeds, the visual line of the driver may lower, causing display information on the steering wheel to be hidden behind the wheel, making it difficult and time-consuming for the driver to recognize, thus reducing convenience.
Innovation Solution
A vehicle operation system that calculates the driver's visual line position and adjusts the display position of information on the steering wheel to ensure it remains visible, using a visual line position calculator and display position calculator, and a display controller to dynamically reposition the display information on a head-up display or meter display to avoid being hidden by the steering wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display position is fixed on the steering wheel, then the driver can recognize display information with less visual line movement, but the display information may be hidden behind the steering wheel when the driver's posture changes
Solution Approach 1:
The display position is made dynamic rather than fixed. The display controller adjusts the display position on the head-up display based on the visual line position calculated by the visual line position calculator, ensuring the display information remains visible even when the driver's posture changes during driving
Solution Approach 2:
The system uses feedback from the visual line position calculator to adjust the display position. The display position calculator continuously monitors the driver's visual line position and adjusts the display location accordingly, creating a closed-loop control system that maintains visibility reliability
2Reliability
If the driver changes posture to view hidden display information, then the display information becomes visible, but it takes much time and effort which is troublesome especially at high vehicle speeds
Solution Approach 1:
The system performs preliminary action by proactively adjusting the display position before the driver needs to change posture. The visual line position calculator and display position calculator work in advance to position the display information in a location that is currently visible, eliminating the need for the driver to spend time adjusting their posture

AI summary
A vehicle operating system for controlling a control target device by performing a predetermined operation of a driver on a steering wheel of a vehicle, includes: a visual line position calculator for calculating a visual line position of the driver; a display position calculator for calculating a display position on a display arranged on a far side of the steering wheel from the visual line position of the driver using a calculation result of the visual line position calculator and a position coordinate of the steering wheel, the display position not hidden behind the steering wheel; and a display controller for displaying display information indicating a content of the operation on the steering wheel at the display position.
