8 8 The Message People with disabilities can do almost anything in almost any scientific field. People with disabilities are often highly motivated to pursue careers in accessibility research.

9 9 What We’ll Do Today Models of Disability Data History – Disability and HCI Accessibility Research at UW Discussion

10 10 Models of Disability Medical Model –Disabled people are patients who need treatment and/or cure. Rehabilitation Model –Disabled people need assistive technology for employment and everyday life. Legal Model –Disabled people are citizens who have rights and responsibilities like other citizens. Accessibility to public buildings and spaces, voting, television, and telephone are some of those rights. Social Model –Disabled people are part of the diversity of life, not necessarily in need of treatment and cure. They do need access when possible.

11 11 Technology Prosthesis –Augmentation to restore lost function. Call it a “cure.” Assistive technology –Popular in rehabilitation literature. Emphasis on the need for assistance. Access technology –Allows an activity that would be difficult to impossible to achieve without it. Emphasis not on restoring function, but on achieving an end goal by whatever means possible. –Examples: Screen readers, video phones, wheel chairs

12 12 What We’ll Do Today Models of Disability Data History – Disability and HCI Accessibility Research at UW Discussion

13 13 Basic Data 16% of US population to ages 15 to 64 is disabled. 10% of the workforce is disabled 5% of the STEM workforce is disabled 1% of PhDs in STEM are disabled

14 14 Demographics General Population Source: U.S. Census Bureau, Survey of Income and Program Participation, 2002

15 15 Demographics Ages SOURCE: U.S. Department of Education, Office of Special Education Programs,

26 26 ANATOMICALLY CORRECT TESTBED ROBOTIC HAND Yoky Matsuoka MacArthur Foundation Award 2007

27 27 Other Centers of Excellence University of Wisconsin –TRACE Center Carnegie Mellon University / University of Pittsburgh –Quality of Life Center Georgia Institute of Technology University of Colorado MIT

28 28 What We’ll Do Today Models of Disability Data History – Disability and HCI Accessibility Research at UW Discussion

29 29 Concepts in HCI User Centered Design –Involve the user at every step Universal Design –Design for all users, if possible Design for User Empowerment –Design to enable people to solve their own accessibility problems, if possible

30 30 Lab vs. Field Studies Lab + Log every event, maybe even mental activity + Control the variables + Same tasks - Limited time - Applicability may be suspect Field + Log many events, but not all + Unlimited time + Applicability assured -Different tasks -User logging might be inaccurate

31 31 Challenges Fitts’ Law for blind people –Original Fitts’ law is actual a psycho-visual- motor law not just a psycho-motor law as claimed. –Could lead to a better screen reader? Purpose of Research –Publication? –Dissemination and Deployment?

32 32 Collaboration Meaningful Access Technology Consumers Researchers Industry
