Breaking Barriers in the Metaverse: A Comprehensive Exploration of Accessibility for Users with Disabilities --- Online Appendix

In the post-pandemic era, more and more people are turning to virtual spaces for entertainment, work, education, and social interaction. Despite such excitement, serious concerns have arisen about the accessibility and inclusion of individuals with disabilities in the new digital realm. In this paper, we perform a Systematic Literature Review (SRL) to identify the set of challenges that people with disabilities experience when interested in accessing the metaverse. We gather the solutions proposed in the literature to provide a complete understanding of the accessibility in the current metaverse platforms. We distill a number of take-away messages encouraging researchers and practitioners to further work on the matter to finally empower people with disabilities to fully enjoy the metaverse experience.
