Literature Review of Computer Tools for the Visually Impaired: A Focus on Search Engines

A sudden reliance on the internet has resulted in the global standardization of specific software and interfaces tailored for the average user. Whether it is web apps or dedicated software, the methods of interaction are seemingly similar. But when the computer tool is presented with unique users, specifically with a disability, the quality of interaction degrades, sometimes to a point of complete uselessness. This is because of considering the average user feedback rather than the development of a platform for all (a golden standard). This chapter reviews published works and products that deal with providing accessibility to visually impaired online users. Due to the variety of tools that are available to computer users, the chapter focuses on search engines as a primary tool for browsing the web. By analyzing the attributes discussed below, the reader is equipped with a set of references for existing applications, along with practical insight and recommendations for accessible design. Finally, the necessary considerations for future developments and summaries of important focal points are highlighted.
