The following paper is in keeping with other pieces of research which tend to broaden the role of todayis computer tools so that they be seen as more than just representative. In fact, more and more studies focus on computer tools used as smart guides in the development stages of the preliminary concept. We therefore present a cognitive and interactive device with characteristics that address a theatre designeris requirements. It provides information on the visual quality of seats and optimizes their location in order to improve audience visibility. The working method we introduce will serve as a basis for future implementations when designing theatrical facilities and providing for audience visibility.
