Summary
We implemented a unique evaluation system for a Ministry of Textiles and NIFT sponsored project. It combines a hardware and software based testing system, using computerized image processing to calculate an evaluation score based on different attributes of sewing skills.

The Strategy
Standardize Testing
An unbiased and fair evaluation demands standardized tests with pre-determined benchmarks for consistency across companies and locations.
Make Evaluation Simple
The on-ground evaluators need access to a simple system that prompts them to the next steps. A clean layout combined with straightforward steps to follow can boost the productivity of evaluations, saving time and money.
Avoid High-Bandwidth Demands
Manufacturing units are often located in far-flung places. Any evaluation system then would require to be primarily offline. Once the results have been collated, a simple upload-to-server feature can connect on-ground testing with higher-order processes.
Automate Scoring
To overcome the shortage of qualified evaluators, our scoring system would need to be computer-based. We would need to create an application to read the test results via images, authenticate for quality and score the result based on pre-determined parameters.
The Result
We created a seamless, multiple touchpoint-based testing and marking system for evaluating the skill of sewing machine operators. Our objective and standardized evaluation system makes use of three main parts: A Windows-based desktop application A beautiful and practical web-based, cross-platform app A computer-vision based scoring system
Multiple Touchpoints, Seamless System
We created a seamless testing and automatic marking system with high levels of interoperability that standardizes skill measurement and certification for sewing machine operators. Our easy-to-use system for on-ground evaluators makes assigning tests and capturing results easy, without the need for constant internet connectivity. Our admin-level web app makes accessing and viewing test results simple. Additionally, our automated scoring mechanism makes our evaluations fair, unbiased, and fast.
Authentic, Fair Testing
We randomly assign standardized test-pattern templates which operators try to duplicate and are marked on. We also normalize the quality of results so that scoring is consistent and fair. Additionally, unique bar codes correctly identify operators easily.
Automated Testing Mechanism
Our unique marking system uses computer vision to score valid test submissions. We score each operator on the speed and accuracy of their individual result and their scores are later tallied.
Practical User Interface
We built a simple layout and an intuitive user interface that makes both navigating the desktop application and conducting the evaluation, easy and effortless. Also, our web app user interface makes it easy to monitor and track results.
