Observation and Monitoring - Indirect Observation Protocol
data collection by remote note taking, keyboard logging, video capture
- Users need to be briefed fully; a policy must be decided upon and agreed about what to do if they get “stuck”; tasks must be justified and prioritised (easiest first)
- Video capture permits post-event “debriefing” and avoids Hawthorne effect (However, users may behave differently in unnatural environment)
- with data-logging vast amounts of low-level data collected; difficult and expensive to analyse
- interaction of variables may be more relevant than a single one (lack of context)
