Universal design benefits all, including people…

with disabilities with situational limitations in noisy or noiseless environments where English is a second language learning to read who need hands-free computing using older technology with different learning styles

A Foundation for Advanced Technology

Separation of content from presentation Ubiquitous support for the full spectrum of

input and output devices Closed Captions

Full text archival and searching capabilities Search results can link to specific keyframes

within a video presentation

Reduced cost of accommodation

Including accessibility in the design saves $ over expensive time-sensitive retrofits

Providing accessible online learning saves $ over hiring human readers and scribes

Approaches to Access
