Transparent Support Filter Selection Using Individual Light Sensitivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining light filters are either subjective and user-dependent or objective but limited, failing to account for the full spectrum of light sensitivity factors, leading to filters that do not adequately meet individual user needs.
Innovation Solution
A method that combines objective light sensitivity measurements with subjective user feedback to determine a filter by considering light environments' intensity, spatial, temporal, and spectral components, using a dedicated device to assess discomfort and requiring user input on light environments, calculating scores for filter compliance, and ranking filters based on these scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subjective methods are used to determine filters, then user perception is considered, but the method is too dependent on user judgment and lacks objectivity
Solution Approach 1:
The patent combines subjective user feedback with objective light sensitivity measurements to determine filter characteristics. The system integrates both user perception data (subjective) and measured light sensitivity thresholds (objective) to comprehensively determine the filter that best meets individual user needs, resolving the contradiction between adaptability and measurement precision.
2Measurement precision
If objective methods are used to determine filters, then measurement precision is improved, but the method is limited to measurements and does not account for user perception
Solution Approach 1:
The system merges objective light sensitivity measurements with subjective user perception feedback to determine filter characteristics. This combination allows the method to maintain measurement precision while also accounting for user perception, thereby resolving the contradiction between these two features.
3Device complexity
If known methods are used to determine filters, then the process is simplified, but the determined filter does not fully fit individual user needs
Solution Approach 1:
The system performs preliminary measurements of light sensitivity thresholds and collects user feedback before determining the final filter characteristics. This preliminary action enables the system to customize filters to individual user needs while maintaining a relatively simple determination process through automated measurement and calculation.

AI summary
The invention provides a method for determining at least one filter for a transparent support, the method comprising the following steps: - determining a quantity representative of a light sensitivity threshold of the user; - determining, for each light environment among a group of light environments, an index representative of the level of protection required by the user; - determining a score for each light environment among the group of light environments (40) and for each filter among a group of filters, said score being representative of the capacity of the filter to reach the level of protection required by the user; - determining at least one filter among the group of filters based on the scores of said at least one filter in a plurality of light environments (40) among the group of light environments.
