What do we do?
In this assignment, you will create and test paper prototypes for your design ideas.
You need to build a paper prototype that supports end-to-end scenarios
captured in one or more of your storyboards. This means your paper prototype should concretely present all the elements of a user interface you're envisioning (but not trivial or unimportant components like footer or logo). Your prototype needs to support at least three distinct tasks
. This does not mean you need to build three separate prototypes, but rather this means you need to build one complete prototype that is flexible enough to support the three tasks. You may choose to expand the prototype you made in class. Alternatively, you may choose different tasks, especially if results from testing the initial version suggest that the approach you're taking doesn't seem quite promising.
After building your paper prototype, find at least three participants
to test it. Make sure they are not
friends who know about your project already, or classmates. Preferably, try to find participants who are close to your target user group or persona.
For reference, refer to the course reading
or Hanmail video
we watched in class.
Here's a suggested procedure for building and testing your paper prototype in the second round:
- Write down and print out a briefing for the user: This should include the purpose of your interface and background information that your participant needs to know. Make them simple, short, and clear: 1-2 paragraphs are enough. The reason you shouldn't rely on the facilitator's verbal introduction on-the-fly is to ensure consistency in your introduction.
- Write down all the concrete tasks on index cards: Again, we need this to be written down to ensure consistency. You may read to the user what's written on the index cards. Note that task descriptions should be about the user's goal (e.g., find the cheapest product and add to a shopping cart), not about how to use the interface (e.g., click on the product and drag to the shopping cart icon).
- Decide roles in your team: As discussed in class, you need a facilitator, a computer, and observer(s). Make sure each person clearly understands their roles, what to do, and what not to do. Feel free to swap roles after each participant's session.
- Run the test: After quick ice-breaking, show the briefing to the user. Present one task, watch the user perform the task, and make observations. Observers should note any usability issues the participant encounters. Then repeat with the other tasks.
- Photos of your prototype: Add a 1-2 sentence caption for each significant screen or component, so that a reader who does not know about your project can understand what all the major components of your prototype are designed for. Make sure you hand-sketch, and not print things out digitally. If you had anything printed out, mention why you chose to do so.
- Participants: How many? How did you recruit them? Add demographic information, but do not include their name.
- Briefing: What you presented to the user (1-2 paragraphs long).
- Tasks: The tasks your participants performed (three).
- Observations: List at least 10 usability problems you discovered. Organize them by high-level task or theme, not by each participant or time. But mention which participant ran into the problem by referring to them as P1, P2, ... (e.g., search results did not show the price information (P1, P3)). For each problem, indicate how critical the problem is: high, medium, and low. Finally, show how you plan to address each of the problems in the later stage of your design process.
- Individual Reflections: Each member should write this part on their own, reflecting on their own experience. Merge all members' mini-reports in the final report. Answer the following questions:
- What role did you play in each round?
- What were some of the difficulties you faced playing the role(s)?
- In what way was paper prototyping useful in your project?
- What did your paper prototype not cover or test?
- Studio Reflections: Summarize the feedback from the studio session, and mention how you addressed it or will address it later in the process.
- Updates in DP1/2: If your team revisited needfinding and/or ideation and made updates to your earlier results, briefly describe what has been changed. Note that this is optional.

- Preparation and organization?
- Articulation and clear delivery?
- Effective use of visual aids?
- Time management?
: In studio, your team will present your main findings for 7 minutes, with 5 minutes for Q&A and feedback. You need to prepare a Google Slides presentation, by adding your slides to the link your TA will send you. The slides should be sent to your TA by 5pm on Monday
. Every team member
needs to participate in the presentation. Write down the questions and feedback you receive during your presentation, and reflect on them in your report.
Special note for DP3 studio
: Course staff understands that there might not be enough time to build and test the paper prototype fully before the Monday studio. Until the studio, make sure your prototype building is complete, and at least one participant session is complete (as opposed to three). Individual reflections are not necessary for the studio presentation.
: One report per team. Your report should be submitted as a zip file. The main report should be written in Markdown
(please use the .md
Name the file with your team name, and submit it by visiting this link
. You can submit multiple times until the deadline, and we'll use the most recent version for grading.
