AR Display Color Adaptation for In-Vehicle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle displays, such as head-up displays, face challenges in maintaining visibility due to external views, especially when the display image and external view colors are similar, leading to decreased visibility and potential driver distraction.
Innovation Solution
A moving object equipped with a display unit, imaging unit, arithmetic unit, and control unit that captures images of both the display image and external view, compares their colors, and adjusts the display image's color to be complementary to the external view, thereby enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display image is overlaid on an external view in an AR display, then information provision to the driver is improved, but visibility of the display image decreases when the color of the display image and the external view are similar
Solution Approach 1:
The patent applies color changes by detecting the color of the external view and adjusting the display image color to be complementary or contrasting. The arithmetic unit calculates color differences and modifies the display image colors dynamically to ensure high visibility against the external view background, directly resolving the visibility issue when colors are similar.
Solution Approach 2:
The patent changes multiple parameters of the display image including color, brightness, and contrast based on the external view conditions. The system adjusts these parameters dynamically to optimize visibility while maintaining information provision, addressing both the information loss and visibility concerns.
2Reliability
If the visibility of the display image is enhanced by adjusting color contrast, then driver attention is maintained, but driver distraction may increase due to excessive color adjustment
Solution Approach 1:
The patent implements feedback by continuously monitoring the external view color and adjusting the display image colors in real-time. The system uses the captured image feedback to dynamically optimize visibility while avoiding excessive adjustments that could cause distraction, maintaining a balance between attention and distraction.
Solution Approach 2:
The patent applies dynamics by making the display image parameters (color, brightness) dynamically adjustable based on real-time external view conditions. This dynamic adjustment ensures optimal visibility without static excessive contrast that could cause distraction, adapting to changing environmental conditions.
