Fragment Shadow

Generating 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.

This research is one of the research and engineering Framework called "Superception(Super + perception)", built by Shunichi Kasahara, a researcher at Sony CSL, with the intention of transforming and expanding human perception and cognition using computer technology.

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.
