In the field of human-machine interaction, when the user transmits information to the system he is using, interactivity is the possibility of:
get action from the device (feedback) in real time;
intervene on the service it receives remotely (databases, remote surveillance, communication systems, etc.) There are therefore two types of possible interaction: 1) between user and device; 2) between user and service provider.
In recent years the concept of interactivity has been used in very different meanings, distinguishing interactivity in: "selection interactivity", that is, the widening of the variety of choices available; interactivity understood as an intervention requested of the user; interactivity as an anthropomorphic interface, that is the ability to simulate conversation and human communicative exchange and the ability to "monitor" and observe the uses of the medium, the systematic recording of feedback and the possibility that the user is offered to add their own information to be made available to the public.
An interesting and important aspect could consist precisely in on-line communication, which must be differentiated from paper, television or radio information; in fact, if we take a text published online as a specific case, the reader does not place himself in the passive position of someone who reads a newspaper or simply listening to a news item, but will have the possibility of reacting with different tools. In fact, the author of the text can, for example, insert the e-mail address in the footer, directly giving the reader the opportunity to comment on what he has read, or even give the reader the opportunity to rate the article. . Thanks to these new means of communication and interaction, we can see how the system can adapt to the multiple needs of the user.
Interactivity is an essential component of Web 2.0 within the dynamic Web paradigm: the user can interact with the visited website by adding their own content in the form of comments, judgments, evaluations, multimedia content as usually happens in blogs, forums , wiki systems, social networks, video sharing systems, etc. Another example of interactivity are the data / requests provided by the user to the server through a form.
Interactivity and multimedia in schools
Since the early 2000s, new technologies aimed at teaching are present in Italian schools, which have revolutionized the traditional learning path.
Interactive resources are used not only by young people for studying, but also by teachers: the new multimedia tools (e-learning platforms, electronic registers, etc.) have facilitated the work of the latter by making the preparation time of material shorter. didactic and easier the evaluation of the students.
An important multimedia tool is the "interactive whiteboard" (IWB) which favors a better learning of the student compared to the classic method of the "frontal lesson" between professors and students, and learning of the mnemonic-notional type. The electronic board allows you to reproduce audio and video (with animations, infographics and storytelling) and to connect the e-books of professors and students with the IWB, promoting greater didactic interactivity and better personalization of the educational work.
A very important means of communication can be direct and interactive marketing. The telephone is part of this interactivity as a valid channel, replacing all other media, especially to meet the needs of customers both for sales and for orders and purchases. Interactive marketing has given excellent results especially to companies that
