A few years ago I traveled to Des Moines to work with graphic design students at Drake University. We spent two days discussing, concepting, prototyping and testing data visualizations for low vision users. Interested?  Create your own low vision simulator goggles and more using my resources page.

Below are some key slides from my lecture

" Disability...is a complex phenomenon, reflecting the interaction between features of a person's body and features of the society in which he or she lives." —World Health Organization
"What is universal in life, if there are universal, is the experience of the limitations of the body." Lennard J Davis, Bending Over Backwards: Disability, Dismodernism & Other Difficult Positions
The shifting state of impairment: permanent, temporary, situational
Why does an interface need to respond the same way to each user? Why couldn't each user's experience be unique? How can your interface respond to your unique user's needs?
How can we use an intelligent responsive interface to create barrier -free access?
Barrier-Free Access: Smart, responsive customizable interfaces rather than Universal Interfaces
