Interaction in Digitally Augmented Opera

— This paper reviews an experimental opera production, where digitally augmented content was used interactively during the performance. Projected graphics and spatialized sounds were designed to support the story. The animated 3D graphics acted as virtual stage, narrative element, or reflection of thoughts of a character. The special effects were partly under performers’ direct control, which allows natural timing and gives more freedom for artistic expression.
