Virage : Designing an Interactive Intermedia Sequencer from Users Requirements and Theoretical Background

We present the unrolling of the Virage project and its main achievement : a sequencer for authoring and performing interactive intermedia scenarii. This two years long project addressed the question of authoring and controlling interactive scenarii dealing with several heterogeneous digital media, in the context of the performing arts. The project involved multidisciplinary members including artists and developers and researchers in the fields of social studies and computer science. The main point was the design of a sequencer for scheduling and controlling the triggering of events embedded within the scenarii. We show here howwe adapted a theoretical background, originally conceived for the interpretation of musical scores, to specific requirements in collaboration with field agents. We also describe how these exchanges about the features of the sequencer leaded the software development.
