Remote Optometry Method for Precise Visual Compensation Parameter Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optometry methods for determining personalization parameters of visual compensation equipment are complex, require direct user-optometrist interaction, and often result in inaccurate measurements due to limitations in capturing dynamic behavior and kinetic vision, leading to poor-quality glasses with issues like faulty lens centering and inter-pupillary distance errors.
Innovation Solution
A remote optometry method using an image capture terminal validated by a remote assistance center, which guides the user through a series of postures and ocular fixations to capture accurate images or video sequences, allowing for the determination of various personalization parameters without the need for expensive specific devices, and providing real-time feedback for correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional optometry methods are used with dedicated optometry devices and direct user-optometrist interaction, then measurement precision can be maintained, but device complexity and ease of operation deteriorate due to complex procedures and limited accessibility
Solution Approach 1:
The patent uses a camera to capture images of the user's face and eyes, creating a digital copy that can be analyzed remotely. This replaces the need for complex dedicated optometry devices while maintaining measurement capability through image processing and automated analysis algorithms.
Solution Approach 2:
The system enables users to perform optometry measurements independently at home using their own devices (smartphones, tablets, or computers with cameras). The automated image analysis and AI-driven algorithms guide users through the process without requiring an optometrist's direct intervention, making the service self-sufficient.
2Measurement precision
If conventional optometry methods are used with direct user-optometrist interaction, then personalization parameters can be determined, but loss of time increases due to limited measurement periods and inability to capture dynamic behavior
Solution Approach 1:
The patent captures multiple images or video sequences of the user in different positions and orientations, including dynamic movements such as head rotations and eye tracking. This dynamic approach allows the system to capture kinetic vision and determine personalization parameters under various conditions, improving accuracy while enabling measurements to be completed asynchronously over extended periods.
Solution Approach 2:
The system performs preliminary actions by capturing multiple images and video sequences in advance, which are then processed and analyzed to determine personalization parameters. This allows measurements to be taken during routine activities without requiring dedicated measurement appointments, reducing time loss.
3Ease of operation
If simplified remote methods using computer or digital tablet cameras are used, then ease of operation improves, but measurement precision deteriorates due to image distortions and lack of user position control
Solution Approach 1:
The system provides real-time feedback to users through the application interface, guiding them on proper positioning, lighting conditions, and head orientation. The automated image analysis includes quality assessment that provides feedback on whether captured images meet precision requirements, allowing users to adjust and retake images until satisfactory quality is achieved.
Solution Approach 2:
The patent utilizes multiple dimensions by capturing images from different angles, orientations, and distances. The system processes these multi-dimensional image data sets to compensate for camera distortions and determine accurate personalization parameters, transforming the limitation of consumer camera quality into an advantage through multi-angle measurement.
4Measurement precision
If conventional optometry methods are used, then personalization parameters can be determined, but productivity decreases due to complex procedures requiring limited time periods and multiple measurements
Solution Approach 1:
The system enables continuous capture of images and video sequences during the user's normal activities without interruption. Multiple measurements are taken continuously as the user moves and changes position, allowing the system to accumulate data over time and determine personalization parameters through automated processing, significantly improving measurement efficiency.
Solution Approach 2:
The patent segments the measurement process into multiple independent image captures and video sequences that can be processed separately. The system divides the determination of personalization parameters into distinct analytical steps, allowing parallel processing and automated analysis, which increases productivity while maintaining precision.
