Wearable VR Headset for Remote Binocular Alignment Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing binocular vision alignment are inadequate as they often require patients to be in non-normal positions and do not accurately simulate real-world conditions, leading to incomplete diagnosis of digital eye strain and binocular vision dysfunction, especially during the COVID-19 pandemic where remote testing is desirable.
Innovation Solution
A system comprising a wearable VR headset and a remote computing device that displays different images to each eye, allowing for measurement of binocular alignment in real distances without verbal input, using adjustable prisms and eye tracking to determine phoria and fusional ranges, enabling remote binocular vision assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional binocular vision testing methods are used, then binocular alignment can be measured, but patients must be placed in non-normal positions and the testing does not simulate real-world conditions, reducing diagnostic accuracy
Solution Approach 1:
The patent replaces traditional mechanical/optical testing apparatus with a wearable computing device that displays images directly to the patient's eyes. This substitution allows measurement of binocular alignment while the patient maintains natural head and eye positions, eliminating the need for complex positioning fixtures and non-natural testing postures.
Solution Approach 2:
The system allows patients to perform binocular vision testing independently without requiring examiner intervention for positioning or instruction. The wearable device automatically captures eye position data and calculates binocular alignment, enabling patients to complete assessments in their natural environment without specialized training or assistance.
2Reliability
If in-person binocular vision testing is conducted, then comprehensive eye examination can be performed, but patients face increased risk of COVID-19 transmission in crowded waiting areas
Solution Approach 1:
The wearable computing device serves as an intermediary that transfers the binocular vision testing function from the clinical setting to the patient's environment. By delivering the testing capability directly to the patient through a portable device, the system eliminates the need for in-person contact and crowded waiting areas while preserving diagnostic functionality.
Solution Approach 2:
The system separates the binocular vision assessment from the clinical examination environment by delivering testing images and data collection capabilities to a wearable device. This segmentation allows the diagnostic function to be performed remotely while maintaining comprehensive assessment capabilities through integrated sensors and processing.
3Object-affected harmful factors
If remote binocular vision testing is implemented, then COVID-19 transmission risk is reduced, but existing methods require verbal input from patients and do not accurately simulate real-world viewing conditions
Solution Approach 1:
The system replaces verbal patient input with automatic eye tracking technology that detects and records eye position, gaze direction, and binocular alignment. This substitution eliminates the need for patient verbal responses while capturing precise ocular movement data, and the wearable display presents images at realistic distances and angles that simulate natural viewing conditions.
4Measurement precision
If traditional testing apparatus are used, then binocular alignment can be measured, but the equipment is complex and requires specialized setup and operation
Solution Approach 1:
The wearable computing device integrates multiple functions including image display, eye tracking, data collection, and binocular alignment calculation into a single portable unit. This multi-functional design replaces complex specialized testing apparatus while maintaining measurement precision, as the device can perform various ophthalmic assessments without requiring separate equipment for each function.
Data Source
