Who is a participant in an observational system?
Participant observation. A participant observer becomes part of the action, and observes as an insider. In the case of the park, a participant observer might be a neighborhood resident directly involved in the effort, or might be someone who becomes part of the life of the park for the purposes of observation.
Why is the role of observation so important?
Since we’re most interested in people’s behavior, observing is the most important of these activities because it provides the most accurate information about people, their tasks, and their needs. While interviewing is also very important, the information people provide during interviews isn’t always accurate or reliable.
Why are user observations important in interaction design?
Of course, it’s easy in theory – getting to the meatiest of observations takes practice and a keen interest in your subject. However, user observations are a great way to find out more about how a product is used (or indeed how an information visualization is used) and to identify any problems that they encounter.
