Interactivity

In the fields of information science, communication, and industrial design, there is debate over the meaning of Interactivity. In the "contingency view" of interactivity, there are three levels: Noninteractive, when a message is not related to previous messages; Reactive, when a message is related only to one immediately previous message; and Interactive, when a message is related to a number of previous messages and to the relationship between them.

Interactivity is similar to the degree of responsiveness, and is examined as a communication process in which each message is related to the previous messages exchanged, and to the relation of those messages to the messages preceding them.
