Transcript

  • 1. Testing Paper Prototypes
  • 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. 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. 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. Be creative!
  • 6. DEMO
