FakeBand: Virtual Band Music Performance with Balanced Interface for Individual Score/Rhythm Play and Inter-player Expression Coordination

In this poster, we feature a two-user immersive VR music performance system called the “FakeBand”. It resembles the rhythm game for a guitar play-along, but extended in its interaction model and interface design, focusing on the band performance experience in terms of coordination and collective musical expression. Coordi-nating timings for the tempo/accent change begins by the leader and the follower exchanging glances and using bodily gestures - nodding for tempo and large arm motion for accents. The interaction model and separated interface between the rhythm/chord play and music coordination were important in bringing about the active and frustration-free musical experience.
