User Experience in an Interactive Music Virtual Reality System: An Exploratory Study.

The Objects VR interface and study explores interactive music and virtual reality, focusing on user experience, understanding of musical functionality, and interaction issues. Our system offers spatio-temporal music interaction using 3D geometric shapes and their designed relationships. Control is provided by tracking of the hands, and the experience is rendered across a head-mounted display with binaural sound presented over headphones. The evaluation of the system uses a mixed methods approach based on semi-structured interviews, surveys and video-based interaction analysis. On average the system was positively received in terms of interview self-report, metrics for spatial presence and creative support. Interaction analysis and interview thematic analysis also revealed instances of frustration with interaction and levels of confusion with system functionality. Our results allow reflection on design criteria and discussion of implications for facilitating music engagement in virtual reality. Finally our work discusses the effectiveness of measures with respect to future evaluation of novel interactive music systems in virtual reality.
