Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mass vision screening of students faces challenges in accurately confirming student identities, leading to incorrect association of screening results with individual students.
Innovation Solution
The use of personalized stickers with barcodes and facial recognition technology to confirm student identities during vision screening, allowing for accurate association of results with the correct students through a computer system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual identity confirmation methods are used during mass vision screening, then the screening process can be performed quickly and efficiently, but the accuracy of associating screening results with correct student identities deteriorates
Solution Approach 1:
The patent replaces manual mechanical identity confirmation methods (operators asking students for names or checking ID lists) with an automated optical recognition system. The camera captures images of barcodes on student stickers and facial images, then uses image processing and pattern recognition algorithms to automatically verify identities and associate screening results with correct students, eliminating human error while maintaining high throughput.
Solution Approach 2:
The patent uses barcode stickers as copies of student identity information that can be rapidly captured and processed. Instead of requiring operators to manually transcribe or verify student identities, the system captures optical copies (barcode images and facial images) and processes them through automated recognition, enabling both high speed and high accuracy in identity confirmation.
2Measurement precision
If automated image recognition is implemented to confirm student identities, then identity confirmation accuracy is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent segments the identity confirmation process into distinct functional modules: a camera module for capturing images, a barcode recognition module for processing sticker codes, a facial recognition module for verifying student faces, and a result association module for linking screenings to identities. This modular segmentation manages system complexity by allowing each component to be optimized independently while working together in an integrated workflow.
Solution Approach 2:
The patent employs a multi-functional camera system that serves multiple purposes: capturing barcode images from student stickers, capturing facial images for recognition, and potentially capturing eye images for vision screening. This universal imaging device reduces overall system complexity by consolidating multiple functions into a single apparatus rather than requiring separate devices for each function.

AI summary
Various implementations disclosed herein relate to systems, methods, and devices to facilitate mass vision screening of individuals. An example method includes capturing a first image of an individual and confirming an identity of the individual based on the first image. In response to confirming the identity of the individual, the method may further include capturing one or more second images of an eye of the individual; determining one or more health metrics of the individual based on the one or more second images, and transmitting, to a remote device, the identity of the individual and the one or more health metrics of the individual. The one or more health metrics may include at least one of a pupillary distance of the individual, a pupil size of the eye of the individual, a complete refraction of the eye of the individual, or an alignment indicator of the eye of the individual.
