revoir is an installation, a platform and medium to enable audience participation with and within works of art. It makes the act of observation a part of the creative act: by observing, the audience influences the artwork. The creative act becomes open-ended, the artwork becomes a fluent exchange with its audience, and the barriers between artist, artwork and audience are broken down.
revoir works by facial emotion detection: a camera interprets the facial expression of an observer. These data then alter the work of art according to parameters given by the artist.
The separation of artist, artwork and audience was first questioned by Marcel Duchamp. When he says that “the audience completes the creative act, becoming, in a sense, artists”, he refers to the interpretation of the audience: “All in all, the creative act is not performed by the artist alone. The spectator brings the work in contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act.” The experience of a work of art is perceived as a property of the outside world, but is in fact a product of our consciousness. Yet, through the very act of watching, an observer affects reality. Under observation, electrons behave like particles; without observation, they behave like waves. According to physicist Pascual Jordan,”observations not only disturb what has to be measured, they produce it.” 19th century portrait photography was often made with naive painted backdrops of sylvan landscapes. This practice attempted to bridge the gap between the new medium of photography and portrait painting and catered to the desire of clients to be part of an artwork.
how it works
The artist assigns visual and audio expressions (fractions of images, films, audio) to different emotional states (happy, neutral, sad, excited…). As the observer changes his facial expression, the image assigned to this emotional state becomes more visibly blended in. aura can be realized as a large-scale wall or as a framed screen.
