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.Sheizaf Rafaeli defined Interactivity as "an expression of the extent that in a given series of communication exchanges, any third (or later) transmission (or message) is related to the degree to which previous exchanges referred to even earlier transmissions. Rafaeli, 1988

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.

Human to human communication

---

Human communication is the basic example of interactive communication. Because of that, many conceptualizations of interactivity are based on anthropomorphic definitions. For example, complex systems that detect and react to human behavior are sometimes called interactive. Under this perspective, interaction includes responses to human physical manipulation like movement, body language, and/or changes in psychological states.
