> "The other trick if finding out the difference between power and knowledge. You dont start at the top if you want to find a story, you start in the middle. Because its the people in the middle that do the work"

## Methods
|
|
- Participant [Observation](out/notes/observation.md)
|
|
- Apprenticeship
|
|
- set a partnership with the people to be observed
|
|
- be taught the steps in the process
|
|
- observe the practives
|
|
- validate what you are observing with those observed as you go along
|
|
- e.g.,
|
|
- apprenticeship is eVision user
|
|
- task: find in which room INFO203 is
|
|
- problem: I do not have a timetable in eVision like students
|
|
- allows you to capture the context of use and the issues and needs
|
|
- what do people do now
|
|
- what values and goals do people have
|
|
- how are these particular activities embedded in the larger context
|
|
- similarities and differences across people
|
|
- other types of context that are relevant -> time of day, social context
|
|
|
|
- [Interviews](out/notes/interviews.md)
|
|
- avoid leading questions
|
|
- choose sample representative of real users
|
|
- often impractical
|
|
- can be structured or semi-structured
|
|
- effective for high level
|
|
|
|
- Longitudinal studies
|
|
- sporadic use -> when the product is used rarely
|
|
- used when you cannot use observational studies
|
|
- diaries
|
|
- scale better than direct observation (less time consuming)
|
|
- give people a diary to copmlete
|
|
- structred task
|
|
- can use journals, camera, voice, video
|
|
- tailor the recording to the context
|
|
- may require practice, training, reminding
|
|
- use of ntifications, digital calendars, phone calls
|
|
- Experience sampling
|
|
- use txt, phone calls , calendars, notifications to recieve feeback or actively remind people
|
|
- choose interval depending on study context
