Diary studies - A primer

  1. 1. Diary StudiesA primer Boon Yew ChewThe Research Thing SapientNitro25 May 2011 @boonych
  2. 2. View from 30,000 feet""Intro"Examples"Some Practical Tips
  3. 3. A diary study involves participants reporting theiractivities over a specific period of time, usuallyapart from the researcher and in their normal dailylives.
  4. 4. Diary Studies in HCI""John Rieman"1993
  5. 5. BenefitsUnderstanding context and environmentUnderstanding rare / infrequent eventsEcological validityRemoteSampling over a durationBridges qualitative and quantitative studiesFlexibility
  6. 6. Participants keep a record of“When” data “What” data Date & time Activity / taskDuration Feelings / moodActivity / task Environment / setting
  7. 7. Recorded in various ways Etc…
  8. 8. …at various times1.  Randomly2.  At specific intervals3.  Based on activity
  9. 9. Structured or unstructured data Structured Yes/no Select a category Date & time Multiple choice Unstructured Open-ended Opinions / thoughts / feelings Notes / comments
  10. 10. Ways to gather dataFeedback (now) Elicitation (later) Record everything in situ Record aspects or triggersNo follow up Follow up with interview“What” data To elicit “why” and “how”Mostly structured Mostly unstructuredCan be burdensome Participants may forget
  11. 11. “Hygiene” aspectsAt the beginningIntroduction / get-to-know-youDemographicsInstructions / Setting expectationsAt the endFollow-upThanks / token giftReflection
  12. 12. Thanking your participantsOne off vouchersSpread incentives across longer durations“Keep the Flip camera” incentive
  13. 13. Pitfalls Belief biasBehaviour adjustmentRamp-up timeFailure to recall
  14. 14. Alternatives / forms of diary studies Experience Sampling Method (feelings, mood) Cultural Probe (photo, video, sketches) Technology Probe (prototypes, experimental artifacts)
  15. 15. My NordiCHI ‘10 paper
  16. 16. What motivates image use on theinternet? •  Goal - understand motivations of image use•  9 participants (5F / 4M, age 24 – 59)•  Short note of activity involving an image, photo or visual•  Periodic interviews (about once every two days)•  About 20 activities per person
  17. 17. Interview fieldnotes in spreadsheet
  18. 18. Grounded theory – coding the data•  Coded each activity•  Example codes: instructional, informational, learning, fun, communication, social, etc.•  Kept a count of activities and codes
  19. 19. Group themes from affinity map
  20. 20. Ethnographic “memos”
  21. 21. Modeling, creating a framework
  22. 22. Keeping it real – stories & examples
  23. 23. Findings 1.  Observed patterns of image use2.  Lots of interesting stories3.  Data can be used to explain, extend or simulate more research both qualitatively or quantitatively
  24. 24. What I’d do better 1.  Plan better (recording setup, coding shorthand, etc.)2.  Record coding and affinity maps3.  Compare against participants’ browser histories?
