Vehicle Occupant Monitoring Camera Layout for Unobstructed Swiping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing occupant monitoring systems in vehicles face challenges in effectively monitoring occupants' conditions due to field of view obstructions by occupants' limbs when using touch panels, leading to decreased usability and accuracy in determining occupants' states, especially during swiping actions.
Innovation Solution
The occupant monitoring device incorporates a camera module positioned on the back of the display operation panel, allowing it to image occupants without obstruction, and uses pre-captured frontal image data in conjunction with current data to determine occupants' conditions, ensuring accurate monitoring while allowing swiping operations without restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display operation panel is positioned in front of the occupant for easy operation, then the ease of operation is improved, but the field of view of the imaging device is obstructed by the occupant's limbs during swiping actions
Solution Approach 1:
The imaging device is inverted from its conventional position in front of the occupant to a position behind the display operation panel. This inversion allows the imaging device to capture images of the occupant's face and upper body without being obstructed by the occupant's limbs during touch panel operations, while the display operation panel remains in its conventional front position for ease of operation.
Solution Approach 2:
The imaging device is positioned in a different spatial dimension (behind the display panel) rather than in the same plane as the display. This dimensional change allows simultaneous optimization of both operation ease (front display position) and monitoring accuracy (unobstructed camera view from behind).
2Measurement precision
If the imaging device is positioned to capture clear images of the occupant, then the monitoring accuracy is improved, but it obstructs the occupant's view of the display or requires complex positioning
Solution Approach 1:
The imaging device is merged with the display operation panel assembly, positioned behind the panel. This integration allows the imaging function to be incorporated into the existing display structure without requiring separate complex positioning mechanisms, thereby maintaining monitoring accuracy while minimizing device complexity.
Solution Approach 2:
The display operation panel serves a dual function: as the user interface in front of the occupant and as a structural element that houses and positions the imaging device behind it. This self-service approach eliminates the need for additional complex positioning structures.

AI summary
An occupant monitoring device for a vehicle includes a display, a controller, and an imager. The display is configured to display an operation screen for an occupant in the vehicle. The controller is configured to execute control based on an operation type determined as an operation performed by the occupant on the operation screen of the display. The imager is configured to image the occupant in the vehicle. The controller is configured to avoid executing the control based on the determined operation type in a case where the operation type performed by the occupant at least involves movement toward the imager.
