I use a designer methodology. I consider the viewer as a user, and the artwork as an object or product. The artwork is designed to be used by the viewer, while aiming personal goals: questioning free will and decision making mechanisms, exploring the links between emotional and rational, and making the viewer sensitive to his environment.
Interactive media appears to be a particularly powerful means of expression to address these issues. The interactive artwork uses spatiotemporal dimensions, plus the dimension of eventualities: what could possibly happen, depending on certain factors, mainly the behavior of the viewer.
The function of the work is therefore to involve the viewer, to make him active. The aesthetics must serve this purpose. It must catch attention, arouse interest, while allowing the viewer to understand the operating system of the work. Thus, form follows function.
