Key Ideas • “Universal Access” for telecommunication is not sufficient for computing services  Due to the power of Internet, the interaction is more complex than simply providing access • Online support communities and electronic societal services are provided  lower levels of computing skills and certain conditions of disabilities

  3. Key Ideas • How to make information and communication services “usable” to everyone?  universal usability • Three research agenda: - Technology variety - User variety - What users know and what they need to know (evolutionary learning)

  4. Key Ideas • A good starting point to use knowledge base (evaluation metrics) to apply to IT artifact and conduct design research

  5. Strengths and Weakness • Big research questions in the human computer interaction research • Diverse context of human computer interaction  contingent factors and universal rules  potential research questions • A few research references under each of the three research agenda

  6. Authors • Ben Shneiderman Professor in CS, University of Maryland http://www.cs.umd.edu/~ben/ Research area in human-computer interaction

  7. Questions • Do you think universal usability is a profitable business model? Songs from iTune is only playable by Apple devices? • Is it true that universal usability is profitable for certain types of computing services while not so for the others?
