Mixed Reality Light Adaptation for Eye Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers experience eye adaptation issues when moving between areas with significantly different light illumination levels, leading to potential accidents and reduced productivity, as they struggle to adjust their vision quickly enough.
Innovation Solution
A computer-implemented method that learns a user's rate of eye adaptation and adjusts the light illumination level in mixed reality (MR) device representations to match the user's adaptation rate, ensuring a smooth transition between different light environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workers move quickly between areas with different light illumination levels, then productivity is improved, but eye adaptation issues occur causing safety problems
Solution Approach 1:
The system performs preliminary action by detecting the user's destination location and proactively adjusting the light illumination level in the MR display before the user physically arrives at the destination. This allows the user's eyes to gradually adapt to the upcoming light change, eliminating the harmful effect of sudden illumination changes while maintaining quick movement between areas.
2Ease of operation
If the light illumination level is adjusted to match user's adaptation rate, then eye strain is reduced, but the system complexity increases
Solution Approach 1:
The system implements feedback by continuously monitoring the user's pupil size through the MR display camera and using this information to dynamically adjust the light illumination level. This closed-loop control ensures the illumination matches the user's real-time adaptation state, providing eye comfort while managing system complexity through intelligent control rather than hardware complexity.
Solution Approach 2:
The system performs self-service by automatically detecting the user's destination and adjusting the light illumination without requiring manual user input or configuration. The system serves itself by using the MR display camera to monitor pupil size and autonomously controlling the light output, simplifying the user interface while maintaining sophisticated light adaptation.
3Speed
If sudden light illumination changes are used in MR displays, then the display responds quickly to environment changes, but user vision cannot adapt causing safety issues
Solution Approach 1:
The system applies dynamics by making the light illumination level adjustable and adaptive rather than fixed. The illumination dynamically changes based on the user's real-time pupil size measurements, allowing the display to respond quickly to environmental changes while simultaneously adapting to the user's visual capabilities, thus resolving the contradiction between speed and safety.

AI summary
A computer-implemented method, according to one embodiment, includes learning a rate of eye adaptation that a first user's pupil muscle adjusts. In response to a determination that the first user is moving from a first location having a first level of light illumination to a second location having a second level of light illumination, it is determined whether a difference in the levels has a potential for causing eye adaptation issues for the first user. In response to a determination that the difference in the levels has a potential for causing eye adaptation issues, a level of light illumination that will allow the first user's pupil muscle to adjust at the learned rate of eye adaptation is determined. A first representation of the second location is output for display on a mixed reality device worn by the first user upon the first user entering the second location.
