Archimedes Hawaii

• 1992 Founded at Stanford University
• to ensure that all people have full access to
  information in whatever form it is encountered
• 2003 Relocated to University of Hawaii
• Support offered from UH when last NSF grant ended
• Focus of Archimedes Project Universal Design
• Any person with any disability being able to use
  any IT device (AT)

4
Assistive
Technology

• What is AT?
• Developing and using technology to make things
  that were previously inaccessible to a person
  accessible.
• What is the purpose of AT?
• To help anyone who because of culture, education,
  age, disability, etc. may not be able to do
  things that other people may do.

5
Overview
