Solution Overview
Problem
Augmented reality systems face challenges in maintaining an intended appearance of virtual content over a physical real-world environment due to environmental characteristics like ambient light and color, which can alter the perceived visuals of virtual content.
Innovation Solution
A system comprising a content component, device component, environment component, determination component, modification component, and presentation component that adjusts display values of visual parameters to match expected values, using machine-readable instructions to ensure the virtual content appears as intended despite environmental interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual content is presented on a display without environmental compensation, then the presentation system is simple, but the appearance of virtual content is altered by environmental characteristics such as ambient light and color
Solution Approach 1:
The system performs preliminary actions by capturing environmental characteristics (ambient light and color) before presenting the virtual content. The environment component captures these characteristics and the determination component calculates compensation values in advance, so that when the virtual content is displayed, the appearance remains consistent without requiring complex real-time adjustments during content presentation.
Solution Approach 2:
The patent introduces intermediary components (environment component and determination component) that mediate between the virtual content and environmental factors. These intermediaries capture environmental data, calculate appropriate compensations, and provide corrected display values to the presentation component, thereby isolating the complexity from the main content delivery path.
2Reliability
If display values are adjusted to compensate for environmental interference, then the intended appearance of virtual content is maintained, but the processing time and computational resources increase
Solution Approach 1:
The system performs environmental capture and compensation calculation as preliminary actions before content presentation. The environment component captures ambient light and color characteristics, and the determination component pre-calculates the necessary compensation values. This approach moves computationally intensive tasks to the preparation phase rather than during real-time content display, reducing processing time during the actual presentation.
3Object-affected harmful factors
If the system captures and processes environmental characteristics, then environmental interference is minimized, but the device complexity and number of components increase
Solution Approach 1:
The patent implements multi-functionality by having the environment component capture multiple types of environmental data (ambient light and color characteristics) through a unified interface. The determination component then processes all this data to generate comprehensive compensation values. This universal approach consolidates what could be separate complex subsystems into integrated components, reducing overall system complexity while effectively addressing multiple environmental interference factors.

AI summary
The systems described herein facilitate providing a virtual content with an intended appearance. The virtual content can be an interactive space. The interactive space may be presented on a display of a presentation device. The display can be a transparent display. The interactive space can be superimposed over a perspective of a physical real-world environment of a user. Environmental characteristics of the physical real-world environment can alter the intended appearance of the interactive space superimposed over a perspective of a physical real-world environment. The environmental characteristics include one or more of a light intensity, color, and/or other visual features of the physical real-world environment. The appearance of the interactive space can be altered to compensate for the environmental characteristics. The appearance of the interactive space can be altered such the user can perceive the interactive space as intended by the creator of the interactive space.
