Transmissive Display Pointer Visibility via Dynamic Color Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmissive display devices, such as head-mounted displays, face challenges in making pointers visible over external landscapes due to color and luminance differences, leading to difficulty in recognizing the pointer image.
Innovation Solution
The transmissive display device incorporates a display control section that adjusts the pointer image's configuration based on features of the external world image, target image, or their composite, including changing color to a complementary hue, pattern directionality, and parallax, to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pointer image is displayed with fixed display configuration, then the device complexity is reduced, but the visibility of the pointer image deteriorates when the external landscape color or luminance affects pointer recognition
Solution Approach 1:
The pointer image display configuration is made dynamic by automatically adjusting its color based on the detected color of the external landscape. The display control section changes the pointer color in real-time according to the external environment, transforming a static display into an adaptive one that maintains visibility across varying conditions.
Solution Approach 2:
The invention directly applies color changes to solve the visibility problem. When the external landscape is detected to have a specific color, the pointer image is displayed in a complementary or contrasting color to ensure visual distinction and maintain readability regardless of the background color or luminance conditions.
2Adaptability or versatility
If the pointer color is adjusted to match external landscape luminance, then the adaptability to different lighting conditions is improved, but the pointer becomes invisible when the external landscape color causes color blending
Solution Approach 1:
The invention prioritizes color contrast over luminance matching. Instead of adjusting the pointer luminance to match the external environment, the system detects the external landscape color and displays the pointer in a contrasting color, ensuring the pointer remains distinguishable regardless of luminance conditions or background color.
Solution Approach 2:
The display control section changes the color parameter of the pointer image based on detected external conditions. By modifying the color parameter rather than solely relying on luminance adjustment, the system maintains pointer distinguishability across varying external landscape colors and lighting conditions.
3Ease of operation
If no display configuration adjustment is made, then the ease of operation is maintained, but the visual recognition of the pointer is lost in colorful external landscapes
Solution Approach 1:
The system performs self-adjustment by automatically detecting the external landscape color and autonomously changing the pointer display color accordingly. This eliminates the need for manual user intervention to adjust display settings, maintaining ease of operation while ensuring reliable pointer visibility through automatic environmental adaptation.
Solution Approach 2:
The display control section automatically changes the color parameter of the pointer image based on detected external conditions. This automatic parameter adjustment ensures the pointer remains visually recognizable without requiring user input, balancing operational simplicity with reliable visual recognition.
