Musical Engagement that is Predicated on Intentional Activity of the Performer with NOISA Instruments

This paper presents our current research in which we study the notion of performer engagement within the variance and diversities of the intentional activities of the performer in musical interaction. We introduce a user-test study with the aim to evaluate our system's engagement prediction capability and to understand in detail the system's response behaviour. The quantitative results indicate that our system recognises and monitors performer's engagement successfully, although we found that the system's response to maintain and deepen the performer's engagement is perceived differently among participants. The results reported in this paper can be used to inform the design of interactive systems that enhance the quality of performer's engagement in musical interaction with new interfaces.
