Ascott claims that as soon as an observer relates to an artwork, he can become totally involved in it—physically, intellectually, and emotionally. But even though the observer in this way becomes an active participant in the production process, it is still the artist who defines the boundaries within which the recipient can act: “In response to behavioural clues in a construction (to push, pull, slide back, open, peg, for example) the participant becomes responsible for the extension of the artwork’s meaning. He becomes a decision-maker in the symbolic world that confronts him.”
