Web accessibility and people with dyslexia: a survey on techniques and guidelines

ABSTRACT

Although the dyslexia has significant occurrence in the global population, ranging from 15 to 20%, not much is known about how developers, designers, and content producers should respect differences and consider people with dyslexia in the Web. In this paper we present a survey regarding the state of the art on dyslexia and Web Accessibility. From the results, we present a set of 41 guidelines that may support website stakeholders (i.e., people directly involved with the design, development, and content) in phases involving design, coding, and Web content insertion. Moreover, we propose a mapping of these guidelines considering the responsibilities of different roles of websites stakeholders. Informed by this survey we expect development teams to objectively consider abilities of people with dyslexia in order to remove accessibility barriers.
