Universal Design GUIDE
This guide can and should be used to design all media. Legally, it is required for "places of public accommodation". For digital media, this is currently not well or consistently defined in the courts or the legal language. New definitions for the existing regulations are due to come in 2018. For more information about accessibility regulations click here.
This guide covers WCAG 2.0 - Level AA accessibility conformance that we can implement using the capabilities that we have. This level is generally considered the minimum requirement for media that is used for government or public accommodation.
