Abstract –We propose a large interactive display with virtual touch buttons on a pale-colored flat wall. Our easy-to-install system consists of a front projector and a single commodity camera. A button touch is detected based on the area of the shadow cast by the user’s hand; this shadow becomes very small when the button is touched. The shadow area is segmented by a brief change of the button to a different color when the shadow covers the button region. Background subtraction is used to extract the foreground (i.e. the hand and its shadow) region. The reference image for the background is continuously adjusted to match the ambient light. When tested, our scheme proved robust to differences in illumination. The response time for touch detection was about 100 ms The industrial applications were controlled by a relay as response to touch detection.
