Paper Prototyping

  1. 1. Testing Paper Prototypes
  2. 2. Wizard of Oz Approach • Users interact with a system they presume to be autonomous • In reality, the system is operated by a human being (who should remain unseen)
  3. 3. Conducting the test Before the test • General icebreaking (introducing yourself, the application) • Encourage the user to talk aloud and not worry • If need be, ask the user whether it’s okay to record their process • Ask some background questions During the test • Initial emotions • Hand out scenarios/tasks • Encourage the user to think aloud! • Don’t give the user any directions on how to use the app
  4. 4. Tasks Good • “Your car tire broke on a Sunday. Find an open tire repair shop near your location and access their website to see their pricing.” Bad • “Use the map interface to find tire repair shops. Upon finding one, tap on it and click on the website URL, so that you’ll be redirected to their website.”
  5. 5. Be creative!
  6. 6. DEMO
