Today we started our yearly Exclusive Design course, one of my favourite courses. Our students will make tailor made prototypes for, and with, real people, not personas. One group of students will work with someone who is deaf. They’ll be experimenting with expressive closed captions and podcast transcripts. Another group will work with a philosophy student with macular degeneration. He needs to be able to add annotations to his digital books, and to manage them, with a screen reader.
