Vision-Based Rear-View Mirror Gaze Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rear-view mirror control technologies, such as touch-controlled and voice-controlled systems, compromise driving safety as they require users to divert attention from the road, and conventional dimming systems lack personalization.
Innovation Solution
A vision-based interactive control apparatus that determines a user's gaze position and direction using image sensors and light sources, allowing the rear-view mirror to adjust its display and reflectivity based on the user's attention and environmental conditions, thereby enhancing safety and personalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch-controlled or voice-controlled systems are used for rear-view mirror control, then the mirror can be adjusted and controlled, but driving safety deteriorates as users must divert attention from the road
Solution Approach 1:
The system automatically detects the driver's gaze position and controls the rear-view mirror without requiring any manual input. The mirror adjusts based on where the driver is looking, eliminating the need for touch or voice commands while maintaining safety by keeping the driver's hands and attention on the road.
Solution Approach 2:
The patent replaces manual control mechanisms (touch screens, voice commands) with an optical detection system using image sensors and light sources. The system captures images of the driver's eyes, detects gaze direction through pupil position analysis, and automatically controls the mirror, substituting mechanical/voice interfaces with an optical field-based control system.
2Object-affected harmful factors
If conventional dimming systems are used for rear-view mirrors, then glare can be reduced, but personalization is lost as all users receive the same dimming level
Solution Approach 1:
The system applies different dimming levels to different regions of the rear-view mirror based on the driver's gaze position. When the driver looks at a specific area, that region receives appropriate brightness adjustment while other areas maintain their original state, creating localized quality adjustments rather than uniform dimming across the entire mirror surface.
Solution Approach 2:
The mirror dimming system dynamically adjusts based on real-time gaze detection. The system continuously monitors the driver's eye position and automatically modifies the dimming level in response to where the driver is looking, making the glare reduction adaptive and personalized rather than static and uniform.
3Adaptability or versatility
If image sensors and light sources are added for gaze detection, then personalized control is achieved, but device complexity increases
Solution Approach 1:
The patent combines the image sensor and light source into an integrated gaze detection module that is embedded within the rear-view mirror assembly. By merging these components into a single integrated unit rather than separate add-on systems, the patent reduces overall device complexity while maintaining the capability for personalized control through gaze detection.
