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
