Blind Spot Display Apparatus with Gaze-Tracking Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle blind spot display systems cannot effectively show the forward blind spot situation, limiting the driver's ability to recognize hazards in this area.
Innovation Solution
An apparatus comprising a front camera, a display device, and a processor that captures and outputs blind spot images at the driver's gaze position, adjusting display position and angle to highlight hazards, and providing guidance to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only an image of a portion occluded due to a specific pillar is selected and displayed through a display installed on the pillar, then the display structure is simple, but it is not possible to display a forward front blind spot situation
Solution Approach 1:
The display device is designed to perform multiple functions: it can display images of specific pillar occlusions, forward blind spot situations, and hazard warnings. The system uses a single camera and display unit that can be configured to show different types of blind spot information depending on the detected hazard type, eliminating the need for separate display systems for different blind spot regions.
Solution Approach 2:
The system dynamically adjusts the display content and position based on the detected hazard type and driver gaze position. The processor selects different image regions and display parameters in real-time according to the situation, making the display adaptable to various blind spot scenarios without requiring multiple fixed display systems.
2Ease of operation
If the display position is fixed on the pillar, then the installation is simple, but the driver cannot intuitively recognize hazards in the forward blind spot
Solution Approach 1:
The system uses a driver monitoring camera to detect the driver's gaze position and provides feedback by adjusting the display content and position accordingly. The processor analyzes the gaze direction and modifies the displayed image to ensure hazards are presented in the optimal position for driver recognition, creating a closed-loop control system that enhances usability.
Solution Approach 2:
The system performs preliminary detection of the driver's gaze position and hazard location before finalizing the display output. By pre-processing the gaze data and hazard information, the system can proactively position the hazard display in the most effective location relative to the driver's natural line of sight, improving recognition without requiring complex real-time adjustments.
3Loss of information
If the display shows all blind spot information, then complete information is provided, but the critical hazard information is not highlighted effectively
Solution Approach 1:
The system applies different display qualities and priorities to different regions of the blind spot information. Critical hazard areas are highlighted with enhanced visual characteristics such as brightness, contrast, or positioning, while non-critical areas are displayed with standard characteristics. This selective emphasis ensures that important information stands out without losing overall information completeness.
Solution Approach 2:
The blind spot information is segmented into different priority levels: critical hazards, potential hazards, and general environmental information. The processor divides the display content accordingly, presenting high-priority hazard information prominently while maintaining lower-priority information in the background or periphery, allowing the driver to quickly identify critical threats while still having access to complete information.
