This paper describes the development of movement-oriented personas and scenarios for representing multiple users of an interactive, immersive environment, designed as an artistic work for a public space. Personas and scenarios were integrated into a user interaction script and linked to a set of movement schemas using Labanotation for group choreography. Enactment of the script within a prototype environment enabled the designers to experience the aesthetic and kinaesthetic qualities of the work, as well as the social interactional aspects of the user experience. This ensured that the experience of those visiting the exhibition was always central to the design process.
