Binocular Visual Stimulus Testing for Faster Ocular Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ocular anomaly detection systems are slow and inefficient, wasting computer processing resources by testing each eye individually and often leading to long testing times and poor user experience due to the need for repeated tests to avoid inaccurate results from eye movements.
Innovation Solution
A wearable device presents visual stimuli simultaneously to both eyes at differing contrast levels, sequentially increasing the contrast until feedback indicates detection, allowing for concurrent ocular anomaly detection and reducing testing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual stimuli are presented to one eye at a time during visual testing, then accurate test results are obtained by avoiding interference from the other eye's movements, but testing time increases and productivity decreases
Solution Approach 1:
The visual stimulus is segmented into two separate stimuli presented to each eye simultaneously, with different contrast levels assigned to each eye's stimulus. This allows independent measurement of each eye's sensitivity while maintaining simultaneous testing, resolving the contradiction between accuracy and speed.
Solution Approach 2:
Different contrast levels are assigned to the stimuli presented to each eye, creating local quality differences. The first eye receives a stimulus at a first contrast level while the second eye receives a stimulus at a second contrast level, enabling simultaneous testing with differentiated measurement conditions for each eye.
2Reliability
If visual stimuli are presented to one eye at a time, then computer processing resources are utilized efficiently for each individual test, but overall testing time increases and user experience deteriorates
Solution Approach 1:
Two separate visual tests for each eye are merged into a single simultaneous testing session. Both eyes are tested at the same time with their respective stimuli, combining what would traditionally be sequential tests into one concurrent process, thereby reducing total testing duration while maintaining reliability.
Solution Approach 2:
The testing process achieves continuity by simultaneously presenting stimuli to both eyes and continuously monitoring feedback from both eyes. This eliminates idle time between testing one eye and the other, maintaining continuous useful action throughout the testing session.
3Measurement precision
If conventional systems test each eye individually with repeated tests, then accurate detection of ocular anomalies is achieved, but computer processing resources are wasted and testing efficiency decreases
Solution Approach 1:
The visual testing system achieves multi-functionality by simultaneously performing two separate visual tests (one for each eye) within a single testing framework. The system processes both eyes' responses concurrently, making the testing system universal for detecting anomalies in both eyes without requiring separate dedicated testing sessions.

AI summary
In some embodiments, a wearable device performs a visual test that includes simultaneously presenting a first eye stimulus for a first eye of a user of the device and a second eye stimulus for a second eye of the user, where the first eye stimulus has a display characteristic level greater than a display characteristic level of the second eye stimulus. The display characteristic level of the first eye stimulus and second eye stimulus are sequentially increased until feedback information indicates detection of at least one of the first eye stimulus or the second eye stimulus by the user. In response to the feedback information indicating such detection by the user, the other stimulus is presented at one or more sequentially increasing display characteristic levels until the feedback information indicates detection of the other stimulus. Ocular anomaly information of the user is generated based on the feedback information.
