In this step you will create a paper prototype that you will use to test with your users. Your "paper" prototype may be constructed from cardboard, paper, post-its, transparencies, etc. If appropriate, your prototype may include more than just "paper".... it may also include constructions in prototyping environments that allow you to use Wizard-of-Oz techniques (page 245 of Interaction Design) to demonstrate or test your system. Remember, you'll be doing user testing on this prototype for the next assignment, so make sure it's complete enough to support basic interaction even if your users make an error and stray from your prescribed task routes.
Your paper prototype must have enough material to support users going through your 3 tasks (1 easy, 1 medium, 1 hard).
