Vehicle Instrument Color Customization with Contrast Threshold Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle graphical displays lack customization options for instrument colors, which can affect readability due to insufficient contrast between symbol graphics and background colors, impacting user experience and productivity.
Innovation Solution
A method that allows users to customize instrument colors on graphical displays, with an automated feature to adjust contrast ratios if necessary, ensuring readability by comparing symbol graphic and background colors and making adjustments to maintain a threshold level of contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users can customize instrument colors freely, then user experience and personalization are improved, but readability may deteriorate due to insufficient contrast between symbol graphics and background colors
Solution Approach 1:
The system automatically evaluates the contrast ratio between selected background colors and symbol graphic colors, providing feedback to the user when the contrast is insufficient. This feedback mechanism allows users to customize colors while ensuring readability is maintained through automated contrast verification.
Solution Approach 2:
The system performs self-service by automatically adjusting or preventing color combinations that would result in poor readability. The contrast evaluation and adjustment features enable the system to maintain readability standards without requiring manual intervention from the user.
2Reliability
If automated contrast adjustment is implemented, then readability is maintained, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent replaces manual contrast evaluation and adjustment with automated computational processing. The system uses software-based contrast ratio calculation and automatic color adjustment, substituting mechanical or manual processes with electronic computation to maintain readability while managing complexity.
3Adaptability or versatility
If color customization options are added, then user experience and personalization are improved, but ease of operation may worsen due to additional configuration steps
Solution Approach 1:
The system provides self-service functionality by automatically evaluating contrast ratios and adjusting color selections when readability thresholds are not met. This automation reduces the cognitive load and operational steps required from users, as the system handles the complex contrast evaluation and adjustment processes autonomously.

AI summary
Aspects of the disclosed subject matter are directed to customizing the colors of instruments that are used to convey vehicle readings. In accordance with one embodiment, a method is provided that obtains input to perform a color change to one or more instruments presented on a graphical display. For each instrument affected by the color change, a determination is made regarding whether a threshold level of contrast exists between a symbol graphic of the instrument and one or more background colors. If a threshold level of contrast does not exist, the contrast ratio between the symbol graphic and one or more background colors is adjusted to at least the threshold level. Then the method causes the graphical display to render the one or more instruments in accordance with the received color selections.
