Were you ever expecting an important phone call? Maybe from a lawyer, from the government, or worst from the doctor. I always end up hanging up on those accidentally. When you add stress to the situation, I can never tell if it's swipe up or swipe down. Just put the words "Answer" or "Hang up" on the screen! Context: Android. Also, there is a book by Eric Meyers and Sarah w.b, Designing for Real Life. Highly recommended for dealing with these issues.
