Simulated Vision Brightness Control for Low-Light XR Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality environments often struggle with low light conditions, making it difficult for users to clearly see the physical environment due to insufficient brightness, which can hinder interaction and navigation.
Innovation Solution
Electronic devices enhance the visibility of the physical environment by displaying images with increased brightness, contrast, and clarity, applying filters and edge enhancements, and adjusting frame rate and fidelity based on ambient light and user context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the electronic device displays images of the physical environment at increased brightness, then the visibility of the physical environment is improved, but the power consumption increases
Solution Approach 1:
The electronic device dynamically adjusts the brightness of displayed images based on real-time detection of ambient light conditions and user interactions. The system transitions between different brightness states (normal, enhanced, maximum) depending on whether the environment is detected as low-light and whether the user is actively interacting with virtual objects, thereby optimizing visibility while minimizing unnecessary power consumption.
Solution Approach 2:
The system changes the brightness parameter of displayed images based on detected environmental conditions. When low light is detected, the device increases image brightness to improve visibility. The brightness level is adjusted as a controllable parameter that can be set to different values (normal, enhanced, maximum) based on the operational context and user needs.
2Illumination intensity
If the electronic device enhances image brightness and clarity, then the visibility of the physical environment is improved, but the processing complexity increases
Solution Approach 1:
The electronic device creates enhanced copies of the physical environment images captured by sensors. Instead of processing and enhancing all visual data continuously, the system selectively generates enhanced brightness versions of images when low light conditions are detected, reducing overall processing complexity while maintaining improved visibility when needed.
Solution Approach 2:
The processing complexity is dynamically adjusted based on operational needs. The device enhances image brightness and clarity only when low light conditions are detected and only for the duration of user interactions, rather than continuously processing all visual data at maximum quality, thereby balancing visibility improvement with processing complexity management.
3Measurement precision
If the electronic device continuously monitors ambient light and user context, then the visibility enhancement is more accurate, but the processing load increases
Solution Approach 1:
The electronic device uses feedback from ambient light sensors and user interaction detection to trigger visibility enhancement only when appropriate. The system continuously monitors environmental conditions and user context, and only activates enhanced brightness processing when low light is detected and user interaction is present, reducing unnecessary processing load while maintaining accurate detection.
Solution Approach 2:
The monitoring and processing activities are dynamically activated based on detected conditions. The device adjusts its operational state between active monitoring/enhancement and reduced processing modes, activating full detection and enhancement capabilities only when low light conditions and user interactions are detected, thereby reducing overall processing load while maintaining measurement precision when needed.
