  9. What Worked • Semi-structured interviews • HCI Experts • Domain Experts • Expert Users • Audio recording, taking notes afterward • Paper and PowerPoint prototypes

  10. What Didn’t Work • Transcribing audio interviews verbatim • High-fidelity prototypes • Never meet user expectations • Result in discussion of meaningless features • Changing the interview protocol during the study • This may not be avoidable in exploratory studies

  11. What’s Hard Work • Distilling quantifiable facts from semi-structured interviews • Making sure users understand low-fidelity prototypes the same way you do • Written interviews • Requires follow-up live interviews • You may never get the results

  12. What I Haven’t Tried (yet) • Broad Surveys • Lab-based Studies • Diary Studies • Field studies (tag-along)

  13. Conclusions • Research is always hard! • It’s relatively easy to: • Schedule interviews • Take notes • Get a good feeling for the subject • It’s relatively hard to: • Talk on the same wavelength as your subjects • Distill useful facts from interview notes • Write up your findings coherently
