Abstract: Large multi-projector displays allow users to be immersed in the data at a grand scale without wearing AR/VR headsets. There has been tremendous advancement in automated projection mapping that uses multiple feedback cameras to stitch and blend images from multiple projectors on curved surfaces of different shapes and sizes. Yet, there is still no easy way to interact with such displays. In this paper, we present a scalable technique that uses the same feedback cameras used for projection mapping to enable multi-user interaction with these displays using multi-colored laser-pens. We also devise methods to achieve the projection mapping and the laser based interaction in the presence of ambient light. This results in an interactive multi-projector system that can be set up and used in an interactive manner in regular illuminated conditions without any disruptions.
