MagicPAPER: Tabletop Interactive Projection Device Based on Kraft Paper.

As the most common material for writing in our daily life, paper is an important carrier for traditional paintings, and its physical touch is more comfortable than electronic screens. In this study, we designed a shadow-art device for human-computer interaction called MagicPAPER, which is based on physical touch detection, gesture recognition, and reality projection. MagicPAPER consists of a pen, kraft paper, and several detection devices, such as AirBar, Kinect, LeapMotion, and WebCam. To make our MagicPAPER more interesting, we developed more than a dozen applications that allow users to experience and explore creative interactions on a desktop with a pen and a piece of paper. Results of our user study showed that MagicPAPER has received positive feedback from many different types of users, particularly children.
