PESI: Extending Mobile Music Instruments with Social Interaction

This paper presents the research project The Notion of Participative and Enacting Sonic Interaction (PESI). PESI aims to extend the engagement of performers in collective music practices using embodied approaches in physical and social interaction. In its design, the mobile phone functions as a tangible and expressive musical instrument, together with an extended system. In this paper, we contextualize the project with associated themes – physical, spatial and social interaction – and with related works. We also present the modular structure of the project, evaluation methods, initial conclusions and paths for future developments.
