Dynamic Vision Testing System for Juvenile Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vision testing methods are often tedious and fail to engage children, leading to difficulties in maintaining their attention and potentially invalidating the results.
Innovation Solution
A vision testing method conducted in a computer-generated environment, such as a computer game-like setting, that uses dynamic and engaging sequences of test images to assess visual acuity and other aspects of vision, allowing for remote testing over a computer network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vision testing methods are used, then the testing process is simple and controlled, but the person's attention cannot be maintained and the results may be invalid
Solution Approach 1:
The patent transforms static vision test charts into dynamic computer-generated environments with moving images, animations, and interactive elements. This dynamic approach maintains juvenile attention while assessing visual acuity, resolving the contradiction between test reliability and person engagement.
Solution Approach 2:
The system changes the parameters of the testing environment from traditional static visual charts to computer-generated dynamic content with varying themes, colors, and motion patterns. This parameter transformation improves engagement while maintaining measurement validity.
2Stability of the object's composition
If conventional vision testing is conducted, then the testing conditions are well controlled, but the testing process is tedious and restrictive
Solution Approach 1:
The patent replaces the mechanical system of physical vision charts and in-person testing with a computer-based digital system. This substitution maintains controlled testing conditions while reducing the restrictive nature of the environment and enabling remote administration.
Solution Approach 2:
The computer-based vision testing system serves multiple functions: it controls testing conditions, engages juveniles through game-like environments, enables remote testing, and provides automated scoring. This multi-functionality resolves the contradiction between controlled conditions and environmental complexity.
3Ease of operation
If conventional vision testing methods are used, then the testing procedure is straightforward, but it does not appeal to juvenile persons
Solution Approach 1:
The system employs dynamic, game-like computer environments with moving images and interactive elements that appeal to juvenile persons. The underlying testing procedure remains straightforward, but the presentation is adapted to different age groups through engaging visual content.
Solution Approach 2:
The patent changes the visual parameters and thematic content of the testing environment to appeal to different age groups while maintaining the core testing procedure. This allows the system to be adaptable to various juvenile populations without complicating the fundamental testing process.

AI summary
A method for testing a person's vision is disclosed. The method includes providing, for display to the person, one or more sequences of test images, each test image including one or more test symbols. For each test image, a target symbol is identified to the person. The person then views each test image in the sequence and activates a control in response to recognising a test symbol that replicates the shape of the target symbol. At the completion of the sequence, a parameter value associated with the activations is processed and correlated with a vision metric. A system for testing a person's vision is also disclosed.
