Interaction

Interaction is a form of communication that takes place between two or more people or between people and the objects designed for them. In the context of this essay it is Human-Computer Interaction (HCI). This type of interaction includes three basic principles of interactivity. The first rule being “input and output”, if input is added it should result in output, and output should result in input, thus creating a cycle. The second principle is “inside and outside”. This refers to what occurs inside a users mind or what he feels and experiences, in relation to what is outside, or what he sees. The last principle is “open and closed”, whether the output has a number of possibilities, or a single one. There are a number of ways in which human-computer interaction may be carried out.
