Put your name and email address on all assignments.

Think about computer programs that you have used. Each program has characteristics of their user interface that make them easy to use and other characteristics that make them harder. Identify three or four characteristics of a user interface that seem to separate "easy" interfaces from "difficult" ones. Is the context of use important for evaluating the characteristics?

Write a short essay with the following sections:

  1. List and explain the characteristics you have described.
  2. Select a computer program that you feel has a "good" interface and explain why it satisifies the characteristics you have identified.
  3. Select a computer program that you feel has a "poor" interface and explain why it satisifies the characteristics you have identified.
