3D Model Accessibility

This article discusses how Scott Vinkle did an experiment to explore the usability and accessibility of 3D models used in web content. Vinkle introduces 3D models, and discusses the barriers they present to users that rely on assistive technology when navigating the web, and defines a list of basic criterea to define an accessible 3D model. This experiment featured Google's <model-viewer> web component, which enables users to interact with 3D models digitally. Vinkle tests how <model-viewer> interacts with different mobile and desktop environments, screen reading devices (including VoiceOver, JAWS, and NVDA), and web browsers. The experiment results are displayed in a table, and feature notes and observations about 3D model user experiences. This resource also provides recommendations to update <model-viewer> and improve accessibility to users with assistive devices; an improve the usability of 3D models.
