I-PWA: IoT based Progressive Web Application For Visually Impaired People

Abstract

A person needs vocational training to get ready for a job that demands a particular skill set. The same opportunities and educational opportunities as those offered to the sighted must also be made available to persons who are visually impaired. The Internet of Things (IoT) has swiftly grown, enabling every object to be incorporated into and linked to the internet. The IoT system's complexity also influences the education industry, which still uses manual processes. The IoT's smart technology has completely changed the way things work now. Even with the IoT explosion, there is currently no software that can provide those with visual impairments practical training. The proposed I-PWA will provide them the tools they need to become independent by enabling them to receive adequate vocational training in the field of their interest. The website includes voice recognition and gesture control for navigation while IoT-based navigation with the use of motion controller devices to traverse across our website will help it evolve to the next level. Braille reading and music systems can be learned through this web-app using haptic feedback from their mobile device. The Availability of audiobooks in the app's library will also help them to gain additional knowledge on various topics. One on One tutoring feature will connect them to their own mentor and ease the learning process. The site outperforms most other websites in terms of offering a good user experience, which includes load time and visual stability, with a Cumulative Layout Shift (CLS) score of 0.002, Time to Interactive (TTI) of 0.4 seconds, Speed Index of 0.8 secs, Largest Contentful Paint of 1.2 seconds and First ContentfulPaint of 0.4 secs.
