We propose the concepts of virtual light and virtual shadow with the aim of achieving a mixed reality environment focused on shadows. In this proposal, we divide the concept of virtual shadow into four categories, and among them, implement four types of interactive applications: (a) real to virtual shadows for rigid objects; (b) real to virtual shadows for non-rigid objects; (c) image-based virtual to virtual shadows, and (d) virtual to real shadows. In these applications, we can see the shadow of a real object projected onto the virtual world and vice versa. These proposed concepts should contribute to the realization of a mixed reality environment that provides a novel sense of interaction
