Dynamically Adjustable Display for Light-Adaptive Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies for devices like work machines and generator sets struggle with maintaining user readability under varying lighting conditions and accommodating different levels of color blindness, leading to difficulties in differentiating the importance of displayed information.
Innovation Solution
A dynamically adjustable display system that adjusts its hue configuration based on ambient light conditions and uses consistent contrast ratios to prioritize icons, allowing users to differentiate between priority and non-priority elements, with optional color code selection through user testing for color blindness accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adaptive recoloring with different color palettes is used to improve readability, then color differentiation is enhanced, but user perception of information importance is affected and readability in various lighting conditions deteriorates
Solution Approach 1:
The system changes the luminance parameter of displayed elements based on ambient light conditions. In bright environments, luminance is increased to maintain visibility, while in dark environments, luminance is decreased to prevent glare and maintain comfort. This dynamic parameter adjustment resolves the contradiction by adapting readability to lighting conditions without relying on color palette changes that would affect information perception.
2Loss of information
If color palettes are optimized for readability, then information differentiation is improved, but accommodation of color blindness and varying user abilities deteriorates
Solution Approach 1:
The system segments the information display into multiple hierarchical levels using contrast ratios. Critical information is displayed with higher contrast ratios while less critical information uses lower contrast ratios. This segmentation approach maintains clear information differentiation without relying on color alone, thereby accommodating users with color blindness while preserving the ability to distinguish information importance.
3Ease of operation
If multiple color palettes are used to differentiate information importance, then visual differentiation is enhanced, but consistency in information perception deteriorates
Solution Approach 1:
The system applies different contrast ratios to different local regions or elements of the display based on their information importance. High-priority elements receive higher contrast ratios while low-priority elements receive lower contrast ratios. This local quality approach maintains visual differentiation for information hierarchy while ensuring consistent perception across the entire display, as all elements follow the same contrast-based hierarchy principle rather than using multiple color palettes.

AI summary
Systems and methods for operating a display of a device are described herein. The display is configured to adjust the hue of the display depending on the ambient light conditions around the display. To assist a user of the device in determining a priority condition of the device, the device is configured to use color contrasts to focus the attention of the user to one or more icons on the display, thus prioritizing icons relative to other, lower priority icons associated with other conditions of the device. Additionally, the contrast used can be adjusted by the user to potentially account for varying degrees of color blindness. The display can be set to one or more test contrasts, whereby a user selects the contrast that works the best for the user.
