AR Display Position Correction for Illuminance-Induced Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visibility of display information presented using augmented reality technology can be affected by changes in surrounding illuminance, leading to difficulties in visual recognition, and the presentation position may deviate from the intended position due to variations in light emission periods.
Innovation Solution
An information processing apparatus and method that acquires information on relative movement between a viewpoint and display information, and light emission periods, to correct the presentation position of the display information in real-time, ensuring accurate positioning and improved visibility across varying illuminance conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emission period is controlled to improve visibility of display information, then the visibility is improved, but the presentation position deviates from the intended position
Solution Approach 1:
The system performs preliminary calculation of the light emission period based on surrounding illuminance before actual display. By predicting the optimal light emission period in advance and using this prediction to adjust the presentation position, the system compensates for the deviation that will occur during the light emission period, thereby maintaining position accuracy while improving visibility.
Solution Approach 2:
The system continuously monitors surrounding illuminance and adjusts the light emission period accordingly. This feedback mechanism ensures that the light emission period is optimized for current environmental conditions, which in turn allows for accurate presentation position correction. The feedback loop between illuminance detection, light emission period adjustment, and position correction resolves the contradiction between visibility and position accuracy.
2Illumination intensity
If the light emission period is extended to improve visibility in high illuminance environments, then the visibility is improved, but the deviation of presentation position is more pronounced
Solution Approach 1:
The system calculates the light emission period in advance based on predicted surrounding illuminance conditions. By determining the optimal emission period before display occurs and using this prediction to pre-correct the presentation position, the system maintains position accuracy even when extending the light emission period to improve visibility in bright environments.
Solution Approach 2:
The system dynamically adjusts multiple parameters including both the light emission period and the presentation position based on surrounding illuminance conditions. By coordinating the change in emission period with a corresponding adjustment in presentation position, the system achieves improved visibility without sacrificing position accuracy, resolving the contradiction between these two parameters.
