tailieunhanh - Lecture Human-computer interaction (3rd) - Chapter 17: Models of the system

Chapter 17 describes the use of general mathematical notations used in software engineering to specify and analyze abstract descriptions of interactive systems. In the previous chapter we looked at the specification of dialog. In this chapter we will look at ways of modeling the semantics of an interactive system. The dialog just tells us about what user actions are legal at any point, but here we will be interested in what the user’s actions do to the system. |
