AR Content Lighting Simulation via VLC Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality (AR) systems fail to consider ambient light sources in real-world environments, leading to a non-immersive experience as AR content appears distinct from physical objects due to lack of light source simulation.
Innovation Solution
An AR system that communicates with visible light communication (VLC) or Internet of Things (IoT) light sources to determine light characteristics, adjusting AR content display to simulate the effect of ambient light sources, thereby enhancing the immersive experience by matching the appearance of AR content with physical objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If AR content is displayed without considering ambient light, then the AR content can be displayed with vibrant colors and high contrast, but the AR content stands out from physical objects in the real world environment, harming the immersive experience
Solution Approach 1:
The system dynamically changes display parameters of AR content based on detected ambient light characteristics. The AR generator adjusts color, brightness, and other visual parameters of AR content to match the ambient lighting conditions, making the AR content blend seamlessly with physical objects in the real world environment.
Solution Approach 2:
The system uses feedback from light sensors and cameras to detect ambient light characteristics, then adjusts AR content display parameters accordingly. This closed-loop feedback mechanism ensures AR content continuously adapts to changing lighting conditions, maintaining immersion throughout the user experience.
2Shape
If the AR system uses opaque portions to improve AR content appearance, then the AR content can include the color black and appear more realistic, but the system does not consider the ambient light, causing AR content to stand out from physical objects
Solution Approach 1:
Instead of using fixed opaque portions, the system dynamically adjusts the transparency, color, and brightness parameters of AR content based on ambient light detection. This allows AR content to maintain its shape and outline while adapting its visual properties to match the surrounding environment.
Solution Approach 2:
The system transitions from static opaque portions to dynamic, adaptive display elements. The AR content's visual properties change in real-time based on ambient light conditions, making the transition from non-adaptive to adaptive behavior.
3Device complexity
If AR content is displayed without simulating ambient light effects, then the display process is simpler, but the AR content does not blend with physical objects, reducing user immersion
Solution Approach 1:
The system introduces light sensors and cameras as intermediary devices to detect ambient light characteristics. These sensors act as mediators between the physical environment and the AR content generation process, providing the necessary information to adjust display parameters without significantly complicating the overall system architecture.
Solution Approach 2:
The system replaces complex manual lighting simulation with automated sensor-based detection and algorithmic processing. Instead of mechanically adjusting display parameters, the system uses electronic sensors and software algorithms to automatically adapt AR content to ambient lighting conditions.

Function Achieved in This Case
The AR system effectively simulates the impact of ambient light sources on AR content, making it appear more like a physical object, thus improving user immersion by dynamically adjusting display characteristics based on light source characteristics and location.

AI summary
Embodiments herein describe an AR system which communicates with light sources in a real world environment to simulate the light sources having an effect on AR content being displayed in the AR system. In one embodiment, the AR system determines the light characteristics of the light sources such as their color, specularity, beam spread, brightness, or illumination pattern. These light characteristics can contribute to the ambient light in the real world environment which affects the appearance of the physical objects in the environment. The AR system can adjust how the AR content is displayed to simulate the AR content being affected in a similar manner by the light sources. As such, the AR content appears to be more like a physical object (rather than a virtual object) thereby providing the user with a more immersive experience.
