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. 10 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.

Design for User Empowerment Design to enable people to solve their own accessibility problems, if possible 29 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 30 Challenges Fitts Law for blind people Original Fitts law is actual a psycho-visualmotor law not just a psycho-motor law as claimed. Could lead to a better screen reader? Purpose of Research Publication? Dissemination and Deployment? 31
