Exploratory sequential data analysis

Abstract
In many areas of HCI, investigators make video or audio recordings of humans working with computers and other humans. These recordings capture verbalizations, actions, and often general aspects of the working environment as well. The investigator then explores and analyses these data in the light of some HCI research or design issue. Protocol analysis, video analysis, interaction analysis, conversation analysis, discourse analysis, sequential data analysis, task analysis, etc., are all examples of such research activity. What they have in common is a concern with handling dynamic, on-line, event-driven behavior that unfolds over time and with capturing the essence of that behavior in summary statements.
