Progressive Symbol Rendering via Additive Color Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable heads-up displays face challenges in effectively drawing user attention to content while maintaining an unobtrusive presence in the user's external environment, requiring a balance between being aesthetically pleasing and attention-catching.
Innovation Solution
The method involves progressively displaying a symbol by combining multiple intermediate color components, where each component overlaps partially to achieve the final color, with dynamic linewidth adjustments and layering, allowing for a smooth and captivating visual presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple intermediate color components are displayed to draw user attention to content, then the content becomes more noticeable and attention-catching, but the display becomes more complex and may detract from the external environment
Solution Approach 1:
The symbol is divided into multiple intermediate color components (first instance, second instance, third instance) that are displayed separately and then combined. Each instance has a different intermediate color (e.g., yellow, cyan, magenta) and is drawn at different times, allowing the display system to build up the final white symbol through additive color mixing without requiring all colors to be displayed simultaneously at full intensity.
Solution Approach 2:
The display system dynamically adjusts the linewidth of each intermediate color instance during the drawing process. The linewidth varies over time as each instance is drawn and then undrawn, creating a temporal dimension to the color mixing process. This dynamic adjustment allows for smooth visual transitions and maintains aesthetic appeal while capturing user attention.
2Illumination intensity
If intermediate color components are drawn with overlapping instances to create the final symbol color, then the visual presentation becomes smoother and more captivating, but the drawing process takes more time
Solution Approach 1:
Each intermediate color instance is drawn for a limited duration and then undrawn, creating a periodic display pattern. The first instance is drawn and held, then the second instance is drawn and overlaid, followed by the third instance, and finally all instances are undrawn. This periodic drawing and undrawing of each color component creates a smooth visual transition while managing the total display time efficiently.
Solution Approach 2:
The intermediate color instances are drawn in a predetermined sequence (first, second, third instances) with each instance prepared and displayed in advance of the final symbol completion. This preliminary action allows the system to build up the color composition step-by-step, ensuring smooth visual transitions while maintaining control over the total drawing time.
3Manufacturing precision
If the linewidth is dynamically varied to match the symbol linewidth during drawing, then the visual precision and aesthetic appeal are improved, but the control complexity increases
Solution Approach 1:
The linewidth parameter of each intermediate color instance is dynamically changed during the drawing process. The linewidth is adjusted to match the target symbol linewidth, and this parameter change is applied to each instance as it is drawn. This allows for precise visual matching of the final symbol appearance while using a relatively simple control mechanism that adjusts only the linewidth parameter.

Function Achieved in This Case
This approach ensures that the content is both aesthetically pleasing and effectively captures the user's attention without detracting from the external environment, enhancing the user experience by providing subtle yet noticeable visual cues.
Implementation Method 1
the second instance is at least partially transparent and the first intermediate color and the second intermediate color combine to display the color of the symbol where the second instance overlaps the first instance

AI summary
Systems, devices, and methods that display visual symbols are described. A visual symbol has a color and a linewidth. Multiple instances of the symbol are concurrently and progressively drawn, one on top of the other, in the display area of a display device. Each respective instance has a respective intermediate color. The respective intermediate colors combine to produce the color of the symbol where the respective instances overlap in the display area. Each respective instance also has a respective linewidth and the respective linewidths converge to the linewidth of the symbol as each instance is progressively drawn. A backwards progression through the same sequence is employed to regressively undraw a symbol from the display area of the display device. Computer program products comprising processor-executable instructions for performing the methods are also described.
