What is the target of observations? What are it’s advantage against a interview?
- observing potential users to unterstand contexts and needs or to evaluate the design of a interactive technology
- People often do not do what they say, behavior across time period instead of impression in time point, people might not remember details in theis past experiences
Direct vs indirect observation
Direct: observe with own eyes what people are doing
indirect: analyse records of people’s activiy (e.g. diary )
lab vs field observation
lab: controlled enviroment (e.g. at usability lab)
field: uncontrolled - visit people in their enviroments
explain the method ‘Think-Aloud Commentaries’. What could be an limitation?
direct observation method, by which user verbalize their thoughts as they move through the interface. As limitation user could act unnatural, filtered.
explain the method ‘Contextual Inquiry’. What are the 4 steps to run it?
fieldwork, semi-structured interview, where users are first asked a set of standard questions and then observed and questioned while they work in their enviroments.
1. Getting a overview: introduce, set the context
2. transition: establish the apprenticeship model, agree to may interrup to ask question
3. main interview: observe the user and ask questions as they arise
4. wrap-up: summarise what you learned and get feedback of your impressions from the user
gibe one example of indirect observation in uncontrolled enviroment. Briefly explain the method.
Diary studies. User keep track of activities or events in a form of log for a certain time frame.
List two possible limitations of diary studies
