Abstract
With recent advances in the past decade in the web, websites have grown past being simple pages of content and have evolved to become more interactive with their audiences. The increase in complexity has contributed to more possibilities in creativity and user experience. Websites now have many features such as dynamic content, user-interactive elements and user-controlled animated content. Browsers and web technologies have also evolved to give developers and creators more control over visual responsiveness and design of their websites. Although the added features bring about richer experiences, they do not come without drawbacks for groups of people that are unable to navigate through these new complexities for proper usage. The visually impaired community encounters many accessibility issues with the addition of complex non-text based elements. Current assistive tools such as screen readers are able to make text-based content accessible, but struggle to parse through more visual and user-interactive elements and provide accessible navigation. The responsibility of making websites more accessible falls upon web developers,their site navigation design choices and the extent to which they make non-textelements interpretable by assistive tools.
