Eye-Tracking Rear View System for Adaptive Image Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear-view mirror systems require manual adjustment for each driver and seating position, leading to inefficient visibility and potentially risky vehicle control during driving, as they do not adapt automatically to the driver's eye position.
Innovation Solution
A rear view system utilizing cameras and screens that adjust the displayed image based on the driver's eye position without mechanical movement, using a combination of rear, overhead, and side cameras, along with an eye sensor to stitch and slide images on rear and side screens, allowing for automatic adjustment and control via eye movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of rear-view mirrors is performed for each driver, then the visibility can be adjusted to individual needs, but it requires time and manual intervention which reduces productivity and convenience
Solution Approach 1:
The system automatically detects driver eye position using sensors and autonomously adjusts the rear-view mirror angles without requiring manual intervention from the driver, making the system serve itself
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated system using eye position detection sensors and electronic control mechanisms to adjust mirror angles, substituting mechanical hand-adjustment with sensor-based automatic control
2Adaptability or versatility
If the inner rear-view control system is used, then the back of the vehicle can be viewed, but it does not adapt to different sitting positions during driving
Solution Approach 1:
The system dynamically adjusts mirror angles based on real-time detection of driver eye position, allowing the control system to adapt continuously to different sitting positions and driving conditions rather than remaining static
3Ease of operation
If the driver controls the vehicle navigator during driving, then navigation functions can be accessed, but it causes risky actions
Solution Approach 1:
The patent replaces manual hand control of the navigator with eye-tracking based control, using ocular movement detection to operate navigation functions without requiring the driver to take hands off the wheel or visually divert attention from the road
