This research consists in the exploration of technical, aesthetic and conceptual means to create multidisciplinary installations that place the visitor's perception at the heart of an artistic proposition. When the perception of a work varies according to the position or the movement of the person observing it, or when this person is presented with a disturbing phenomenon that they cannot describe or interpret, their own perception becomes the focus of their attention. The work is no longer a finished object that the audience sees from the outside, but rather an open system of which they are an integral part. This approach forms the keystone of my project. It will unfold through the search for interdependencies between sonic, visual and spatial elements as well as the exploration of perceptual paradox and confusion. Although my work is rooted in sound, it is now open to new aesthetic challenges and practices. The practical exploration of these disciplines is envisioned in four areas: psychoacoustics and composition strategies, sound diffusion techniques, materials and plastic elements, and finally color and light. I also wish to broaden my approach to installation and discover ways of conceiving it in the context of larger social systems (the city, communities, virtual spaces). This research aims to instill in our culture the idea that perception, which is a form of awareness, is also a selective and distorting activity - a form of ignorance. I believe that there is a social and cultural stake in revealing both the content of our perception and the dynamic, less apparent structures that govern it.
