Interactive art is a form of art that involves the spectator in a way that allows the art to achieve its purpose. Some interactive art installations achieve this by letting the observer or visitor "walk" in, on, and around them; some others ask the artist or the spectators to become part of the artwork.

Works of this kind of art frequently feature computers, interfaces and sometimes sensors to respond to motion, heat, meteorological changes or other types of input their makers programmed them to respond to. Most examples of virtual Internet art and electronic art are highly interactive. Sometimes, visitors are able to navigate through a hypertext environment; some works accept textual or visual input from outside; sometimes an audience can influence the course of a performance or can even participate in it. Some other interactive artworks are considered as immersive as the quality of interaction involve all the spectrum of surrounding stimuli. Virtual reality environnements like works by Maurice Benayoun and Jeffrey Shaw are highly interactive as the work the spectators – Maurice Benayoun call them "visitors", Char Davies "immersants" – interact with take all their fields of perception.
