DIFICULDADES DE USUÁRIOS CEGOS NA INTERAÇÃO COM A WEB: UMA ANÁLISE SOBRE AS PESQUISAS

Web Accessibility aims to allow anyone to understand and interact with content from a Web page, regardless of disabilities or other factors that may restrict access. Studies show that, despite a large amount of work done in the area, people with complete visual impairment (blind) still have difficulty to interact with the Web. In this context, it is necessary to identify the key aspects that influence the difficulties of the blind users to interact and understand the services and information available on Web. From the identification of the actual difficulties reported by the blind, it is possible that solutions are formulated and defined measures to be taken to minimize these difficulties. This article presents an overview of the work and research in the literature, and identifies  the difficulties of the blind in interaction with Web pages.  Therefore, a systematic review was performed for this purpose. Additionally, the data gathered from the literature in order to provide a set of classes of the identified problems are analyzed. The results of the review show that many of the problems faced by blind people are not even addressed by the main references to authors and Web developers to make their Web pages accessible.
