Visual Aid Determination via Defect-Inserted Reading Test
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with central field vision loss, such as age-related macular degeneration, face challenges in oculomotor control due to visual anomalies like central scotoma, which existing methods fail to accurately detect and address effectively, impacting reading and exploration abilities.
Innovation Solution
A method involving a specific reading test with introduced defects in text, where the individual's errors are assessed using an optical indicator to determine the most suitable visual aid, such as magnifying glasses or electronic aids, to correct visual anomalies and improve reading conditions.

Engineering Contradiction Analysis
1Measurement precision
If conventional reading tests are used to assess visual anomalies, then the test procedure is simple, but the detection precision of visual anomalies such as central scotoma is insufficient
Solution Approach 1:
The text is segmented by introducing specific defects (isolated letters, spaces, or symbols) at predetermined locations between words. This segmentation allows the test to specifically target and detect visual anomalies in central vision areas that conventional continuous text cannot reveal. The defects are strategically placed to mask potential scotoma zones, forcing the individual to encounter reading errors that reveal the presence and characteristics of visual anomalies.
Solution Approach 2:
An optical indicator is introduced as an intermediary element that quantifies reading errors and translates them into measurable data about visual anomaly characteristics. The optical indicator system processes the raw reading error data and converts it into standardized metrics that characterize the size, position, and impact of visual anomalies such as central scotoma, enabling precise detection without requiring complex diagnostic equipment.
2Adaptability or versatility
If visual aids are selected without precise detection of visual anomalies, then the selection process is quick, but the suitability of visual aids for individual needs is poor
Solution Approach 1:
The method performs preliminary detection and characterization of visual anomalies through the defect-introduced reading test before visual aid selection. The optical indicator system pre-establishes the individual's visual profile by measuring reading errors against the known defect patterns, creating a baseline characterization of scotoma size and position. This preliminary data enables rapid matching with appropriate visual aids without requiring time-consuming follow-up assessments.
Solution Approach 2:
The system incorporates feedback loops where reading errors are continuously monitored and used to refine the characterization of visual anomalies. The optical indicator provides real-time feedback on reading performance, allowing the system to adjust and optimize the determination of visual aid suitability. This feedback mechanism ensures that the selected visual aids are precisely matched to the individual's specific visual needs while maintaining an efficient process.

AI summary
The invention relates to a method for determining means of a visual aid following the behaviour of an individual during a specific reading phase. The main feature of a method according to the invention is that it comprises the following steps, a step of subjecting the individual to a test involving the specific reading of a material comprising a text comprising a series of common words and into which errors have been inserted between said words at predefined locations, a step in which the individual reads said text out loud, a step of assigning an optical indicator linked to the reading errors identified and making it possible to characterise the quality of reading, a step of selecting the most appropriate visual aid means depending on the determined optical indicator.
