シャドウプレイ/shadowplay shows an experimental interaction paradigm built with the Projector Camera Toolkit, developed during Guest Research Project v.1 at YCAM Interlab.

This video demonstrates some shadowplay experiments, built around the idea of using two projectors that are perfectly aligned. The projectors display the inverse images of each other, so that without interference the screen appears white. When an object enters the space, the structure hidden in the projection is revealed in the shadows. The technical challenge of aligning the projections and calibrating the colors of the projection is solved with the Projector Camera Toolkit, using structured light scanning and some novel feedback-based calibration techniques.
