Instant Adaptation Enrichment Technique to Improve Web Accessibility for Blind Users

Abstract

The Internet in general and the web are considered the main medium of remote communication. They are important sources of information and services to all the users. Assistive technologies and tools facilitate web accessibility to help users with special needs by delivering the content of the webpages in a form that is understandable by these users. However, these assistive technologies and tools often face certain obstacles in delivering the information because of the confusion of web design elements caused by poor webpage design or carelessness in following the web accessibility guidelines. In this paper, we list the minimum required web accessibility guidelines formulated on the basis of a comprehensive review of WCAG 2.1 guidelines to be followed while developing webpages for visually impaired users. We then introduce a tool intended to enhance web accessibility for such users. We tested the tool on a few websites and observed that it significantly improved the webpage accessibility of these websites.
