iPhone touch keyboard study

• 60 participants (20 experienced users each on
  iPhone, Blackberry, phone texters)
• Entered 6 messages on own phone
• Non iPhone users also tested iPhone
• Rated preferences

4
iPhone touch keyboard study results

• iPhone had more errors (5.6 / msg.) than hard
  mini-QWERTY (2.1 / msg.) or phone keypad (1.4 /
  msg.)
• Rate of entry on iPhone and mini-QWERTY same
• Practice improves speed but not error rate
• Hard QWERTY keyboard preferred

Anthropometrics and Ergonomics

• Anthropometrics -- the measurement of the size
  and proportions of the human body.
• Ergonomics -- The applied science of equipment
  design, as for the workplace, intended to
  maximize productivity by reducing operator
  fatigue and discomfort.

About intellectual property

• Intellectual property the ideas behind your
  project
• As far as I know

20
Finishing the design cycle

• We still have a couple more steps to complete the
  design cycle!
• Goal for the class was to get you through the
  design cycle
• Evaluation

21
User study plan

• Ive emailed feedback
• Feel free to ask me more at office hours today,
  200-330, 6th Floor alcove in Soda
• We need to talk about this more

22
More specific detail

• What is starting point?
• How will you instruct the participant to achieve
  the desired endpoint?
• What is the list of questions you will ask?
• Neutral wording
• Anchor words for Likert scales

23
Meaningful tasks and measures

• Installing and making sense of application may be
  important
• Install this application, explore, tell me what
  you think it does
• Compare with complete list of features
• Completion time may not make sense for thinking
  or creating tasks

24
Study logistics

• Realistically, no more than 5 tasks
• Preferably, no more than 12 survey questions
• Preferably, no more than 10 open-ended interview
  questions
• Keeping the study interesting, not tedious for
  the participants
• You only have 2 weeks

25
Study logistics (2)

• Most studies will require facilitator and
  separate observer
• Many consent forms were missing contact info (for
  questions later)
• Sample form link on web site, Nov. 8
• Think aloud requires at least one practice task
• Volunteer to participate in other groups studies

26
Almost all were missing

• Any plan for pilot testing!!!!
• When will you do pilot testing? (at least a day
  for modifications before collecting real data)
• How many pilot subjects? (at least one, but a
  couple would be better)
• Will be looking for how you pilot tested, changes
  you made in final report

Go Stanford!
27
More detail on user study

• Need to think specifically about user tasks
• What is starting point?
• Script of what you are asking them to do
• Write out questions for survey
• If Likert scale, also write out anchors

28
Final report project presentation

• Due week of Dec. 4 6
• Convince project manager to give this project the
  green light
• Final report on user study
• Project presentation on project
• Final individual assessments
• Make sure teaching team has access to facebook
  application by 500 Nov. 30

29
Final report

• Report how you conducted the user study and
  summarize what you learned from it
• Focus on what changes you would make based on the
  user study
• Next steps in the development

30
Final report sections

• Brief review of need and introduction of project
• Evaluation
• Methodology
• Activities studied (illustrate with application
  screenshots)
• Pilot test and changes made from pilot
• Summarized data
• Analysis and Conclusions
• Changes based on user study
• Future Workwhat should be done next
• Next steps for development
• Appendices (only if necessary!)
• Informed consent form
• Detailed user data if referred to in report

31
Project presentation

• Every member of team must present!
• Summarize project (video record?)
• 11-minutes (plus 2 minutes for questions and
  switchover)
• Include need (skit possibility)
• Recorded demo (no more than 2 minutes)
• Brief implementation description (architecture
  diagram)
• Focus on user study, what you learned from it,
  design changes
• Future work
