Improving Web accessibility for visually handicapped people using KAI

Abstract

Currently, the vast majority of content published on the Internet is inaccessible to visually impaired users. However, designers have guidelines that guarantee the accessibility of pages as well as software tools to facilitate this task. It is necessary to consider the user's perspective too, allowing him/her to participate in the restructuring or presentation process of content. There are few software tools which are able to do this. KAI (Accessibility Kit for the Internet) considers both the user and the designer. It classifies the different components of a published Web page and presents them to the user according to his/her needs. At the same time, it improves their accessibility. KAI is based on a new language, BML (Blind Markup Language) that helps authors develop better structured pages. It provides two levels of independence: original Web code and user platform. KAI includes a mixed audio/touch browser that enables selective reading of contents.
