Projector-camera (pro-cam) systems afford a wide range of interactive possibilities, combining both natural and mixedreality 3D interaction. However, the latency inherent within these systems can cause the projection to 'slip' from any moving target, so pro-cam systems have typically shied away from truly dynamic scenarios. We explore softwareonly techniques to reduce latency; considering the best achievable results with widely adopted commodity devices (e.g. 30Hz depth cameras and 60Hz projectors). We achieve 50% projection alignment on objects in free flight (a 34% improvement) and 69% alignment on dynamic human movement (a 40% improvement).
