Abstract

A system can be used in conjunction with a display configured to display an augmented reality (AR) environment including a virtual object placed in a real environment, the virtual object having a virtual location in the AR environment. The system includes a projector, a memory storing a software code, and a hardware processor configured to execute the software code to: determine a projector location of the projector in the real environment; generate a shadow projection in the real environment, the shadow projection corresponding to the virtual object and being based on the virtual location of the virtual object and the projector location; and project, using the projector, a light pattern in the real environment, the light pattern including a light projection and the shadow projection corresponding to the virtual object.
