Abstract

A method of projecting an image on a physical substrate using a virtual image and a virtual plane includes generating a virtual two dimensional plane and locating a position and orientation of a wand with respect to the virtual plane. The method further includes creating a virtual image on the virtual plane with the wand. An image can be projected on the physical substrate. The projected image corresponds to the virtual image created on the virtual plane. An associated image projection system includes a virtual two dimensional plane. A wand is configured to create a virtual image on the virtual two dimensional plane. The image projection system also has a physical substrate configured to receive a projected image. The projected image corresponds to the virtual image generated using the wand and the virtual two dimensional plane.
