We often think the spectator as a position in front of a representation. We can also think it in terms of process in a particular communication context. Spectatorship could be understood in terms of "spectation" (the spectatorial equal function as we consider "production" for the part of a creator) in the meaningness trial of the work. Through the works Our Broken Voice and We are Forest, the collective of artists Circumstance proposes singular experiences which appear as borderline cases of "show" art, "representational" art and interactive art. It will be a question of understanding how these works incline their spectators and to estimate the critical convergences between them and the theories from these three authors. It will allow us to put forward some essential bases of a contemporary theory of the spectatorial process.
