What is Interactivity?

Interactivity is the process of input and output. The user activates something on the product and then something changes. Hyperlinks are an example of this where the user can click on the link (input) and the computer will go to that location and display the data (output). Interactivity is used to maintain the interest of the audience and to have them engage with the product. Interactivity is useful for education in this way.
