BioDigital believes all humans should be able to understand their health, and we built the BioDigital Human platform to help them do just that.
Because we want to empower all of our users to have an effective and accessible learning experience, we've built our learner-facing product, the Human Viewer, to support Web Content Accessibility Guidelines (WCAG) version 2.1 standards, as described in the report below.

Product Information
Name of Product/Version: BioDigital Human Viewer (December 2022)
Report Date: December 2022
Product Description: The BioDigital Human platform enables users to select and customize interactive 3D models of human anatomy, physiology, disease and treatments and publish these directly into digital resources. The BioDigital Human Viewer is the published application that gets embedded into a website or application via an iframe.
Contact Information: For any questions about the accessibility of this product, please contact the BioDigital Customer Experience team at support@biodigital.com.
Notes:
- BioDigital’s library of 3D models have not been evaluated or updated to meet the WCAG requirements. This report is specific to the Human Viewer, the user interface that displays and allows users to interact with the 3D models.
- For the most accessible experience, we advise enabling the Information Panel and Search tool in your published Human Viewer.
- The Information Panel provides titles and descriptions for each chapter of our 3D models.
- The Search tool provides an Anatomy Tree and Anatomy List, which are screen reader-compatible and enable users to select/highlight, hide, and isolate anatomical structures in the 3D model.
- You can find more information about each of these options on our help center.
