Abstract

As the digital age advances, the internet has become a vital source of information and social participation; And with it, opportunities and benefits are manifested that can only be obtained through this single means. That is why it is essential to ensure that everyone can have equal access and opportunities when browsing the web. This review focuses on investigating the current state of knowledge of web accessibility for people with dyslexia. To achieve this, various computer solutions, design recommendations and study of web accessibility guidelines were reviewed, whose main objective is to improve the experience of users with dyslexia when browsing the web. A total of 120 original articles were extracted from the Scopus database, of which 22 studies met the inclusion criteria. The results showed that many of the web design customization options provided by these solutions were able to improve the web browsing and reading experience for people with dyslexia. In conclusion, this RSL allowed to identify a large number of software-based solutions and design recommendations to provide accessibility to people with dyslexia. Among the most important factors considered in these studies is the organization of content, typography and color contrast. Additionally, it is important to highlight the need to continue adjusting these proposals according to the different opinions and suggestions provided by the participants during the evaluations. And finally, it is recommended to obtain larger samples of participants so that, in this way, more representative results can be obtained during future research.
