Hani Alshamrani, Sam Ferguson, Andrew Johnston · University of Technology Sydney · NIME 2026
Up to four people each carry a BeamPod — a portable handheld projector — and throw a shape onto a shared projection surface. A ceiling camera tracks the projections and reads shape identity plus position, scale and distortion, driving synthesis in real time. The projected shape is a visible, portable voice: you can see your own contribution sitting next to everyone else’s in one visual field.
The floor holds five Spatial Interaction Points, discrete positions that set discrete interaction states, while the geometry of your projection gives continuous expressive control. The part that matters most here is what happens when people move together:
When performers converge in the same region, the shared pitch mapping makes their contributions converge musically, supporting coordination through spatial negotiation.
Walk-up, no prior musical training required.
