Abstract: Disclosed are improvements to augmented reality technology by augmenting a physical scene of a live performance via images projected onto three-dimensional physical scenes with real-time IR signal detection for driving augmentation of the live performance. For example, an improved projection mapping technique is disclosed in which a physical object is augmented with a projection image that is projected onto a physical scene. In some instances, the projection may be made in accordance with a timeline. The timeline may be used to synchronize other actions and behaviors of the system as well as the actions of live performers such as actors and users such as audience members. In some instances, the projection images may be driven by audience or other inputs to the system, such as sensor-based inputs. The sensor-based or other inputs may also or alternatively drive physical components such as actuators that impact the real-world objects.
