IxDworks mini-workshop: Testing Paper Prototyping

  1. 1. IxDworks From Ideas to Paper Prototypes: Hands-on Approaches for Early Stage Projects Valeria Gasik, Darja Tokranova
  2. 2. Quick recap
  3. 3. “Do” -goal To find a doctor To avoid a smoke Too have a laugh User task Paper prototype Explore interesting pictures that elevate one’s mood.
  4. 4. Research Personas Scenarios Use Cases Requirements Design Concept Rapid prototypes Wireframes Interactive demos Evaluation Testing Task analysis Feedback Heuristics
  5. 5. Testing paper prototypes
  6. 6. Most people are happy to dedicate time to help you out with your project, even if it’s just on paper! Although it’s just on paper, plan and be prepared! Usability Wizard
  7. 7. Tasks to test Any type of doable tasks with clear goals but without specific clues of the solution. “Change your password” “Find the nearest shop” “Go to menu and edit settings of your profile” “Rearrange search results based on the location”
  8. 8. Open-ended questions “What do you think you can do with this application?” 1st view Previous action returns an error “What do you think went wrong?” A feature “Do you like it?”
  9. 9. “Er... sure, I like it” “Yeah, I know, it’s awesome.” http://i0.kym-cdn.com/entries/icons/original/000/006/026/futuramafry.jpg
  10. 10. Prepare •Write a simple script for yourself, if you have a lot of testing to do. Number/name questions and tasks to help documentation. •Write down tasks on a separate paper so you can show them to your test participants • Specify, for yourself, end-results for the task. Think about what “task not completed”could stand for.

  12. 12. Roles Team of 2 or 3 Silent Wizard of Oz reacts to user’s actions Observer takes notes http://austintoombs.com/wp-content/uploads/2011/02/DSC_7808-Copy.jpg Participant thinks aloud + Facilitator instructs the user and helps the “computer”
  13. 13. • Start with an icebreaker – it’s not that serious anyway! • Ask background questions, such as “Do you travel often?” • Introduce team and roles • Tell about the test details, such as “Use your hand as this would be your tablet” • Ask user to think aloud and not to stress Start with the task and proceed until completion/problem • Continue with the rest of the tasks • Finalize with closing questions Discuss ASAP
  14. 14. Watch for • Are participants doing what was expected? • Did anything cause frustration or confuse? • Anything new or surprising? • Any paths that you haven’t thought of before? • Was there a clearly preferred solution or path? • Are some paths unused or “misused”?
  15. 15. Reflection and Design Changes E.g. Confusion moments? Bottlenecks in the process? What paths were ignored or barely used? What was clearly missing? etc. Tip: Update the design before the next test.
  16. 16. Did the assumption worked? Test your paper prototype with 1-2 colleagues from another groups.
