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 systemu0027s engagement prediction capability and to understand in detail the systemu0027s response behaviour. The quantitative results indicate that our system recognises and monitors performeru0027s engagement successfully, although we found that the systemu0027s response to maintain and deepen the performeru0027s 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 performeru0027s engagement in musical interaction with new interfaces.
