Vehicle Passenger Detection Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems, such as rear-view mirrors, often fail to provide drivers with a clear view of all passengers without requiring them to divert attention from the road, leading to potential traffic accidents due to brief moments of distraction.
Innovation Solution
A display system comprising a camera unit and processing circuitry that identifies and displays a passenger of interest within the vehicle on a display unit, allowing drivers to maintain focus on the road while communicating with passengers, using parameters like sound, movement, face, and lip recognition to determine the passenger of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver uses the rear-view mirror to see passengers, then the driver can communicate with passengers, but the driver cannot see all passengers clearly and may need to turn around which causes distraction
Solution Approach 1:
The system creates a visual copy of the passenger scene by capturing images with cameras and displaying them on display units. This allows the driver to view passengers through a displayed copy rather than directly observing them in the mirror, eliminating the need to turn the head while maintaining visibility of all passengers clearly
Solution Approach 2:
The system introduces an intermediary display unit between the driver and the actual passenger scene. The display unit acts as a mediator that presents passenger images to the driver, allowing the driver to maintain focus on the road while still accessing passenger information through the intermediary display
2Ease of operation
If the driver turns around to look at passengers, then the driver can see all passengers clearly, but the driver's attention is diverted from the road causing safety risks
Solution Approach 1:
The system creates a visual copy of the passenger scene that can be viewed on display units positioned within the driver's forward field of view. This copy allows complete passenger visibility without requiring the driver to rotate the head, thereby eliminating the harmful distraction effect
Solution Approach 2:
The system transitions from a one-dimensional mirror reflection that requires head rotation to a multi-dimensional display arrangement where passenger images can be presented on multiple display units at different positions, all within the driver's forward view, eliminating the need for head movement
3Loss of information
If the rear-view mirror is used to monitor passengers, then the driver can see passengers, but not all passengers are visible in the mirror at the same time
Solution Approach 1:
The system segments the passenger monitoring function across multiple independent camera units and display units. Each camera can capture different passenger zones, and multiple displays can show different passenger views simultaneously, allowing all passengers to be visible without the geometric limitations of a single mirror
Solution Approach 2:
The system creates a universal viewing solution where multiple display units can present different passenger scenes simultaneously, and the system can adapt to show any passenger combination based on detection algorithms, overcoming the fixed geometric constraints of traditional mirror configurations

AI summary
A display method and a display system for a vehicle includes a display unit, a camera unit, a processing circuitry connected to the display unit and the camera unit configured to cause the display system to determine, by the processing circuitry, the passenger of interest out of at least one passenger present in the vehicle, provide, by the camera unit, the image view of the passenger of interest, and display, by the display unit the image view of the passenger of interest on the display unit.
