Fragment Shadow

Generating Optical Fragmented Shadows with Multi-Projectors Geometry and Color Calibration.

Your Real Shadow is Transformed

The shadow is the most primitive graphic that projects ourselves, and the transformation of own real shadow would induce the changes of our own body sensation. In the calibrated multiple-projection field, your real optical shadow will be fragmented, textured, and immersed in the projection graphic. Your shadow will be transformed, and you will also feel . that you have been transformed. Fragment shadow enables you to experience changes in bodily sensations through visual changes in your own shadow.

Fragment Shadow Technology

The Fragment Shadow system consists of multiple projectors that project onto the same projection surface. With geometry, color and uniformity calibration, multiple projectors output different physically calculated individual images onto the same surface to display one synthesized image.

When human bodies or objects enter the projection space, the occlusion of one projector reveals images from other projectors. Then Fragment Shadow enables generating various visual expression in the optical shadow, not just like usual black shadow.
