This conceptual paper describes a work in
progress in the process of design and implementation of the
Smart Stage, an interactive music system prototype for
collaborative musical creativity in immersive and ubiquitous
environments. This system is intended to have a low entry
barrier, thus more forgiving to users with lesser experience or
knowledge in music, and it is designed with affordances to
support intuitive progress in improvisational performance in a
collaborative setting. We present a preliminary technical
overview of the system and a first case study of a 3D
interaction metaphor for granular synthesis, developed for this
environment.Innovation Agency (Agência de Inovação, ADI, Portugal) and Quadro de Referência Estratégico Nacional
