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

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

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

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

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
