Information Flow During Human-Computer Interaction

Whenever a user operates a computer, information flows across the interface between the two. But what is the nature of this information? How does it flow, how can this flow be quantified? How does the context affect the flow of information? To what extent does the flow depend on the user’s competence before beginning the session on the computer? In this chapter, we will address these and related questions. The goal will be to devise a framework for designing and analyzing human-computer dialogues.
