An Interaction Analysis of System Usage: User-Instructor Interaction on the System named 'iFace'

Abstract

Interaction analysis is a method in ethnomethodology. We use it to analyze the user-instructor interaction on the system named 'iFace.' Our analysis reveals that the user does not understand the instruction about the system given by the instructor at the beginning, and then, as the instructor helps him understand the system's behavior, he comes to be aware of what he is doing. By going through this process in multiple phases, the user increases focus and attention. We argue on the basis of the analysis that the structures are important for designing systems.
