In poem after poem, the late barfly poet extraordinaire Charles Bukowski noted that it wasn't the big things that drove people mad, it was the small stuff: little things not going well, small irritants that over time made you crazythe leaking faucet, the stains that won't come out of clothes, the mobile phone that won't dial. Interaction designers try to ameliorate some of that annoyance, making sure that the products and services people deal with make sense, are usable and useful, and are even engaging and fun. Some of what good interaction designers do is make the world better by removing those little irritants in life, some of which we don't know exist until they are gone.
