Solution Overview

Problem

Digital images projected or superimposed onto surfaces can be difficult to perceive when the surface color matches the image content, such as green text on a green surface, making it challenging for users to distinguish and view the information effectively, especially in environments where changing the surface is impractical.

Innovation Solution

The method involves evaluating the viewing surface and rearranging or recoloring the logical objects of a digital image to maximize their perceptibility by determining the spatial arrangement and coloration based on the surface's light reflection or transmission properties, ensuring the image remains legible and understandable while enhancing visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a digital image is projected or superimposed onto a surface, then the image can be displayed on various surfaces, but the perceptibility of the image deteriorates when the surface color matches the image content

Engineering Contradiction:
Improvedisplay on various surfacesVSAvoidperceptibility of image
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary evaluation of the viewing surface's light reflection or transmission properties before composing the digital image. By analyzing the surface characteristics in advance, the system determines appropriate spatial arrangements and colorations for logical objects that will maximize perceptibility on that specific surface, preventing the perceptibility issue before it occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies different spatial arrangements and colorations to different logical objects based on their specific perceptibility requirements on the evaluated surface. Each logical object is optimized locally for its position and appearance, rather than applying a uniform composition to the entire image, thereby maximizing overall perceptibility across the digital image.

Inventive Principle:
Principle #3Local quality

2Difficulty of detecting and measuring

If the spatial arrangement and coloration of logical objects are changed to improve perceptibility, then the image becomes more visible, but the complexity of image composition increases

Engineering Contradiction:
Improveperceptibility of imageVSAvoidimage composition complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The system changes parameters such as spatial position and coloration of logical objects based on the evaluated viewing surface properties. By systematically adjusting these parameters according to surface characteristics, the system improves perceptibility through a methodical approach rather than arbitrary modifications, managing complexity through structured parameter optimization.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system automatically evaluates the viewing surface and autonomously determines the optimal spatial arrangement and coloration of logical objects without requiring manual intervention. This self-service composition process handles the complexity internally, allowing users to benefit from optimized perceptibility without directly managing the composition complexity.

Inventive Principle:
Principle #25Self-service

3Difficulty of detecting and measuring

If the surface onto which the image is projected is changed to improve perceptibility, then the image becomes more visible, but this is impractical in many cases

Engineering Contradiction:
Improveperceptibility of imageVSAvoidpracticality of surface change
Core Design Contradiction:
Difficulty of detecting and measuringVSEase of operation

Solution Approach 1:

Instead of changing the surface to improve perceptibility, the system inverts the approach by keeping the surface unchanged and modifying the digital image composition to adapt to the surface characteristics. This inversion makes the solution practical by avoiding the need to physically change surfaces while still achieving improved perceptibility through automated image composition adjustments.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Teachings herein compose a digital image so that the image is perceptible on a viewing surface, such as a projection surface or a transparent screen. In doing so, the teachings advantageously recognize a digital image as consisting of one or more logical objects, like buttons of a user interface. Often, logical objects may be spatially arranged within the image and/or colored in different possible ways without substantially affecting the meaning conveyed by the image. Exploiting this, teachings herein evaluate light reflected from, or transmitted through, the viewing surface, and compose the digital image from one or more logical objects that have a spatial arrangement or coloration determined in dependence on that evaluation. The teachings might, for example, place a logical object within the image so that it will be displayed on a region of the surface which has high contrast with the object's colors and/or low color variance.
