"One might take the extreme position that a significant interaction between an artwork and a spectator cannot be said to have taken place unless both the spectator and the artwork are in some way permanently changed or enriched by the exchange."
-David Rokeby
"As Josh Ulm put it, interaction is a conversation. And if you have a really powerful conversation, both of you are going to come out of that conversation changed. And if you enter a similar conversation with another, or even with each other, that conversation will be different because of how you were changed by that interaction. True interaction takes much longer than reaction. It is an evolutionary process. It is a social process"
-Christopher Robbins
"true interaction is two-way"
