, there is debate over the meaning of interactivity. In the "contingency view" of interactivity, there are three levels:
  1. Noninteractive, when a message is not related to previous messages;
  2. Reactive, when a message is related only to one immediately previous message; and
  3. Interactive, when a message is related to a number of previous messages and to the relationship between them.

Human to human communication

Human communication is the basic example of interactive communication which involves two different processes; human to human interactivity and human to computer interactivity. Human-Human interactivity is the communication between people.

On the other hand, human to computer communication is the way that people communicate with new media
New media
New media is a broad term in media studies that emerged in the latter part of the 20th century. For example, new media holds out a possibility of on-demand access to content any time, anywhere, on any digital device, as well as interactive user feedback, creative participation and community...

. According to Rada Roy, the "Human Computer interaction model might consists of 4 main components which consist of HUMAN, COMPUTER, TASK ENVIRONMENT and MACHINE ENVIRONMENT. The two basic flows of information and control are assumed. The communication between people and computers; one must understand something about both and about the tasks which people perform with computers. A general model of human - computer interface emphazizes the flow of information and control at the human computer interface." Human to Human interactivity consists of many conceptualizations which 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.

Human to artifact communication

, interactivity refers to the artifact’s interactive behaviour as experienced by the human user. This is different from other aspects of the artifact such as its visual appearance, its internal working, and the meaning of the signs it might mediate. For example, the interactivity of an iPod

 as experienced by its user. This includes the way you move your finger on its input wheel, the way this allows you to select a tune in the playlist, and the way you control the volume.

An artifact’s interactivity is best perceived through use. A bystander can imagine how it would be like to use an artifact by watching others use it, but it is only through actual use that its interactivity is fully experienced and "felt". This is due to the kinesthetic nature of the interactive experience. It is similar to the difference between watching someone drive a car and actually driving it. It is only through the driving that you can experience and "feel" how this car differs from others.

, the "look" refers to its visual design, while the "feel" refers to its interactivity. Indirectly this can be regarded as an informal definition of interactivity.

A more detailed discussion of how interactivity has been conceptualized in the human-computer interaction literature, and how the phenomenology of the French philosopher Merleau-Ponty can shed light on the user experience, see (Svanaes 2000).

 changes which, in turn, significantly affect society (Flew, 2005). The recent processes of digitizing information and the extension of digitisation to media, currently underpins the latest "new" media evolution. Characteristics of digital data (see Flew, p. 3) make it particularly suited to enabling interactivity. Interactivity is seen as a key association with new media as it basically sets apart the 'old' and new medias. Old media could only offer a sit-back type interaction, whereas new media is much more engaging to their audiences.

Technologies such as DVDs and digital TV are classic examples of interactive media

 in their experiences by viewing material, commenting on it and then actively contributing to it. McMillan states that interactivity can occur at many different levels and degrees of engagement and that it is important to differentiate between these levels. User-to-user interaction via the internet; para-social interaction, where new forms of media are generated online; and user-to-system interactivity which is the way devices can be engaged with by a user.
Lev Manovich (2001) also makes a clear definition of what interactivity means for the user. He refers to 'open interactivity' as actions such as computer programming and developing media systems, whereas 'closed interactivity' is merely where the elements of access are determined by the user. This definition is part of his principle of variability (one of Manovich's key features of new media).
