Advertising Diary Activity Did you remember to fill it out? When did you do it?
As encountered? In a batch?
Were the instructions clear? What was easy/hard about it? Do you think it captured your
exposure to advertising?
Diary studies…
Participants collect data about events As they happen In the context of the event (in situ)
Can think of like a small, longitudinal questionnaire
Often used to prompt interview discussion (similar to observations in a contextual inquiry)
Can help understand rare/infrequent events
Data collection methods
Survey style forms Paper (little training required, but hard to
monitor) Online entry forms Google docs
Photographs, video Digital/disposable camera, mobile phone
Audio recording Voice recorder, mobile phone
Aggregating data online Blogs (text, audio, video) , Twitter Rich and timely information
Type of data recorded
When Date/time Duration Activity/task
What Activity/task feelings/mood Context (environment/setting)
When is data recorded?
Randomly In response to prompts
At specific intervals Based on activity
General types of diary studies Unstructured
Ask participants to report on everyday activities Trying to elicit general themes
Structured Ask participants to report on everyday activities
by answering specific questions about the activity
Combination of question types Can also be used as a form of usability
tests and problem reports Ask them to complete a task and report results,
identify bugs, etc.
Variations based on purposeFeedback (now) Elicitation (later)
Record everything in situ
No follow up Focus on the “what”
data Mostly structured Can be burdensome
on participants and researchers
Record aspects or triggers of an activity
Follow up with an interview to gain more information
Data captured is used to elicit the “why” and the how”
Mostly unstructured Can be problems with
participant recall
Cultural Probe Diary study++ Used to not only record
activities, but capture more of “felt life” Stimulate thought as well as capture
experiences http://www.hcibook.com/e3/casestudy/cultural-probes/ - pack contained
a small disposable camera and a listening glass that participants used to listen at walls and doors and write what they heard. It also contained a small solid state recorder packaged in a sleeve that said 'dream recorder'.
Was used by designers at the Royal College of Art, London, to study the way people see their own homes. The results were used to enable designers to get a 'feel' of the meaning of home for many people.
Experience sampling method (measure feelings, moods)
Technology Probes (prototypes, experimental artifacts)
Snow Day Cultural Probe
Who took part? Did you do all activities? Or a subset? What was easy/hard as a participant?
Preamble: Pretend that I've delivered you a probe kit that
includes a camera, a note pad, and a paper map of the city. I want to understand how stormy winter weather impacts student life and poses barriers.
Complete the following activities:
Cultural Probe activity1. Take a pictures of your "storm info central" - how do you find out about impending/current weather conditions and cancellations?
2. Take pictures of weather impeding your normal daily activities - if you are out and about, use your map to record your path (is it your normal one?) - link pictures to locations if you can
3. Take pictures of how you cope with the weather (any work arounds? alternative activities?)
4. In your notepad, jot down 3 things you like about a stormy day and 3 things that you don't like
5. How could technology have helped you? (jot down or sketch out ideas of technologies that could help you out - don't worry about feasibility - dream big!)
Coordination Challenges
Keeping participants on track Periodic reminders Feedback about the level of detail in responses Progressive incentives, surprise
incentives/gifts (may or may not be allowable by BREB)
Adapting to changes Start analysis as soon as first results arrive May need to re-evaluate the diary format if the
data being captured is not what you expected!
Advantages
Time efficient for researchers Lower cost than direct observations
Can have a broad geographic distribution
Supports contextual reports over time Natural environment
Can give rich data about contexts of use
Disadvantages Participant fatigue
Missed responses (frequency data is generally unreliable – lower bound)
Study drop outs “after the fact” reporting to catch up
Behaviour adjustment Participants need reminders Can be expensive for long durations Volume of collected data can be
overwhelming
Study protocol
Introductory letter Consent form Needs to motivate their participation
Very specific instructions Can be helpful to give an example of a
filled out form (take care not to prime/limit)
Diary form / collection aids
Forms of analysis
Track temporal patterns Look for semantic patterns in visual
data Combine with interview analysis
