Interaction models help us understand the communication between the userand the system. Before we propose a design solution, we must articulate theproblem. In order to understand the problem, we introduce a conceptualmodel of how the user perceives and understands the system with whichthey interact. We frame the design solution in terms of this model. Themodel helps us identify the problem space:what the problem is with the current interfacewhat the users Fnd di±cultwhat functionality the users wantwhether all users have the same requirementswhether users are willing to put time into understanding the problemOur interaction model outlines what users can do with the system, presentsthe concepts necessary to interact with the system, and presents themetaphors and analogies used to convey an understanding of the system.The model is also a shared vision amongst all designers.In this chapter, we introduce the terms used in modeling interaction. Wedescribe Norman's model and an elaboration on that model. We concludewith a description of frameworks for interaction models.MODEL TERMINOLOGYThe terms used in modeling interactions between users and computersincludes the following:goals - user-speciFed objectivesdomain - the area of expertise and knowledge in regard to someworldly activity - consists of conceptstasks - operations on the concepts of the domainintentions - speciFc actions required to meet the goal
