Fragment Shadow (2020)

Credits– Shunichi Kasahara (Sony CSL)– Satoru Higa (BACKSPACE Productions Inc. ) Fragment Shadow is an interactive art of real physical shadows cast by audiences in precisely calibrated projection space. Fragment Shadow system creates a unique projection space with a large screen surface from multiple projectors by comprehensive spatial geometry and color calibration process. When humanContinue reading “Fragment Shadow (2020)”

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 inContinue reading “Fragment Shadow”

Preemptive Action

Preemptive Action: Accelerating Human Reaction using Electrical Muscle Stimulation Shunichi Kasahara / (SonyCSL)Jun Nishida (The University of Chicago)Pedro Lopes  (The University of Chicago)本プロジェクトは、シカゴ大学の西田 惇氏、Pedro Lopes氏との共同研究です。 Even computer actuates us before our will, we perceive  “I did it” in some condition. We investigate time window and foundation of the induction of pseudo Sense of Agency withContinue reading “Preemptive Action”


Egocentric visual augmentation by wearable wide projector HeadLight has a fish-eye conversion lens on the projector which enables much wider projection image. However, the conversion lens produces strong distortion in the projected image with pincushion shape. The Headlight system compensates this distortion based on a fisheye model distortion. Therefore, Headlight enables wide angle visual projectionContinue reading “HeadLight”
