Vehicle Rear Camera Icon Placement for Driver Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera monitoring systems (CMS) in vehicles lack usability improvements, particularly in displaying rearward areas and communicating information to drivers effectively.
Innovation Solution
A driving assistance apparatus with image capturing units for left-rearward and right-rearward areas, display units to show captured images, and a control unit that displays icons for communicating information over the image results, positioned in a corner part corresponding to the upper vehicle body side, enhancing driver understanding and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If icons are displayed over the image capturing result to communicate information to the driver, then information communication effectiveness is improved, but the clarity of the rearward area visualization may be degraded due to potential interference with the image display
Solution Approach 1:
The patent applies local quality by placing icons specifically in corner parts of the display that correspond to upper parts on the vehicle body side of the captured image. This localized placement ensures that icons are positioned in areas that do not interfere with the main visualization of the rearward area, thus maintaining image clarity while effectively communicating information to the driver.
Solution Approach 2:
The patent utilizes the spatial dimension of the display by positioning icons in corner areas rather than overlaying them centrally on the image. This dimensional placement strategy allows both the image capturing result and the icon information to be displayed simultaneously without mutual interference, resolving the contradiction between information communication and image clarity.
2Loss of information
If the display unit shows the area behind the vehicle, then the driver can monitor rearward areas, but the steering wheel may block the driver's view of the display unit
Solution Approach 1:
The patent positions the display unit above the steering wheel in the vertical dimension, allowing the driver to view the rearward area monitoring information without the steering wheel blocking the line of sight. This spatial arrangement resolves the viewing obstruction problem while maintaining effective rearward area monitoring.
Solution Approach 2:
The patent places icons in specific corner regions of the display that correspond to upper vehicle body areas, ensuring that critical information is displayed in locations that remain visible despite the steering wheel's presence, thereby maintaining ease of operation while achieving comprehensive monitoring.
