Empirical Evaluation of Metaverse Accessibility for People Who Use Alternative Input/Output Methods

This research has analyzed the accessibility of the current metaverse platforms from the perspective of screen reader and switch scanning interface users, using the mixture of quantitative and qualitative assessments. To this end, the two representative metaverse platforms, ZEPETO and Roblox, were targeted. As a result, it was found that the current metaverse platforms are not carefully designed with accessibility in mind. Many content elements and controls in the metaverse environment suffers from the lack of alternative text description and appropriate markups which are essential to make it perceivable and recognizable by assistive technology. People with severe disabilities are very likely to find it difficult or impossible to independently navigate the current metaverse environment, because they do not provide any viable means of orientation and mobility in the 3D virtual space at all. The UI/UX of the current metaverse platforms also do not provide adequate feedback to help people with limited sensory/motor functions to understand the purpose and function of it. Overall, thereby, the current metaverse environment is not robust enough to reliably work with a wide range of assistive technologies.
