gSpat: Live sound spatialisation using gestural control

Sound spatialisation is an important component in interactive performances as well as in game audio and virtual or mixed reality systems. HCI practices are increasingly focused on creating a natural user experience and embodied interaction through gestural control. Body movements that coincide with sounds consist of both performed ‘sound producing‘ gestures, and ancillary and communicative movements. Thus, different gestural typologies may relate to the same audio source. Furthermore, gestures may depend on the context in which they have been expressed; in other words, they can carry different semantic or semiotic meanings in relationship to the situation and environment or reality in which they have been enacted. In order to explore these research themes, we are developing gSPAT: a software and hardware system able to drive live sound spatialisation for interactive audio performance using gestural control based on human-meaningful gesture-sound relationships. The ultimate aim is to provide a highly natural and musically expressive sound spatialisation experience for the performer. Here we describe three experiments conducted to explore the possible directions for the future of gSPAT’s development. The tests employ a range of practice-based and ethnographic research methods to establish applicability, naturalness and usability across a range of approaches to the interaction design of the system.
