Light-Occluding Vision Testing Casing With Touch Response Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vision testing devices are slow, subjective, and prone to errors due to human interaction, leading to inconsistent and biased results.
Innovation Solution
A vision testing system with a digital display and auto-mode that allows self-administered tests, using touch-based inputs like swipes to reduce subjectivity and improve accuracy, and includes a remote device and server for protocol management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vision testing is administered by an operator with manual control and recording, then the testing process can be flexibly controlled, but the testing speed is slow and human errors occur
Solution Approach 1:
The system enables self-administered vision testing where the test subject independently interacts with the device through touch-based inputs on a digital display, eliminating the need for operator control and recording while maintaining testing functionality
Solution Approach 2:
The patent replaces manual mechanical operations (operator controlling device, eliciting responses, recording answers) with an automated digital system that processes touch inputs and automatically records results
2Ease of operation

3Device complexity
If traditional vision testing methods are used with operator interaction, then the testing process is simple to administer, but the test duration is lengthy
Solution Approach 1:
The system enables self-administered vision testing where the test subject independently interacts with the device through touch-based inputs on a digital display, eliminating the need for operator control and recording while maintaining testing functionality
Solution Approach 2:
The system presents multiple response options in advance on the digital display, allowing the test subject to quickly select answers without waiting for operator guidance, thereby reducing test duration

AI summary
A vision testing device includes a light-occluding casing for administering vision tests. A viewing station is coupled to the light-occluding casing so a test subject can see a first digital display housed within the light-occluding casing. A second digital display is external to the light-occluding casing and is configured to receive touch-based input. One or more predetermined vision tests are displayed via the first digital display. The second digital display receives input corresponding to the vision test displayed via the first digital display. The second digital display includes response indicators that can be activated via a swiping motion on the second digital display, and a response is recorded as a result of the swiping motion. Each answer corresponding to a swiping motion is stored and output as a result of the vision test.
