Homework 2: Paper Prototype of an Interface

Assigned: Mon, Nov. 1, 2010; Due: Mon, Nov. 8, 2010




  • The first deliverable for PART A is a photocopy of your 3 (or more) sketches. (Keep the originals in case the copies get lost.) Be sure to label the different versions so you can differentiate them in your discussion. Each sketch may be one or more pages.
  • The third deliverable is a discussion (e.g., a sentence or two) about which design you picked for Parts B and C and why you selected that one. This should also be done on a computer and printed.

PART B: You should now decide what are the assumptions for the hardware on which your new design will be implemented. (Note: this is obviously only relevant for devices; not for web pages or desktop applications.) You can either assume:

  2. The interface will be on a computer with a mouse, or
  3. The interface will only use physical buttons around a display-only screen (not a touch screen).


  • The deliverables for PART B are descriptions of the assumptions about your hardware and users.


  • The first deliverable for PART C is a copy of your paper prototype. If you use color in your prototype, then you should turn in color copies. If you have little pieces of paper to represent pop-up menus and so forth, be sure to include copies of those in your turn-in. (Again, keep the originals in case the copies get lost!) Please put your paper prototype into a re-sealable envelope.
  • The second deliverable for PART C is a short description of what tasks you will have users do with the device, and the specific sequence of actions that the user should take with your prototype to achieve those tasks. If these are the same as for your homework 1, please repeat them again here, and mention that they come from homework 1.
  • The third deliverable for PART C is the actual instructions you will give users to tell them to do those tasks. This may be the same as your deliverable for Homework 1 part B, if you are using the identical tasks. In that case, please repeat them again here, and mention that they come from homework 1.
