While 3D user interfaces are often designed with efficiency and accuracy in mind, artistic performances have their own very specific constraints and criteria for a successful interaction in mixed or virtual reality, which have yet to be fully understood. In this paper, we study the design of 3D interactions for a Spatial Augmented-Reality (SAR) display in the context of a cyber-opera. We perform an analysis of design decisions taken during the multiple residencies and lab sessions, and we conduct a reflexive thematic analysis of interviews with the director and actors, which highlight how they integrated the story, the actors’ performance, the audience experience and the technology. We identify four main criteria for designing 3D interactions in performing arts, namely their efficiency, expressiveness, contextualization and legibility, and we derive guidelines for future research and creation.
