Overcoming Accessibility Barriers for People with Severe Vision Impairment in Web-based Learning Environments: A Literature Review

This Research Full Paper presents a literature review about overcoming accessibility barriers for People with Severe vision impairment in Web-based Learning Environments.People with vision impairment face several barriers while interacting with web-based environments.Among them, one can cite the lack of suitability of these environments for the use of screen readers, e.g. if the description of the environment elements are not readable by the screen reader.These barriers are also present in web-based learning environments. In this work we present, through a literature review, the most common accessibility barriers faced by people with vision impairment while interacting with web-based learning environments. In addition, we propose solutions that can mitigate this problem, allowing broad access to distance education environments and a better learning experience with them.
