Choose a computer program you have used. Write a brief essay (say, 2-5 pages) discussing its user interface from your perspective. Be sure to mention how you used the program (dilettante, frequent user, power user, and for what purposes most often), and point out particularly good and particularly bad aspects of its user interface. Try to identify why those aspects of the user interface struck you as particularly good or bad.
This assignment is to be done individually. It will be graded primarily on the quality of your thoughts and observations, but especially bad spelling, grammar, or style will count against you.
