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)

4. 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
5. 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.”
