Technology for disabled users: lessons learned

摘要

I've been interested for some time in "assistive technologies" (technologies for disabled users). My friend Ben is dyslexic, which in his case means he cannot read without the help of another person. I remember some of the games on my old TRS-80 Model-I computer talking to me. Why, I wondered, can't today's computers read to Ben? Another friend, Jonathan, has an unnamed condition that has left him with little use of his arms and legs and taken his ability to speak. He communicates with his family by clicking his tongue: once for yes, twice for no.
