The magicpad: a spatial augmented reality based user interface

In this paper, we describe the novel implementation of a tangible user interface framework, namely the MagicPad, inspired by the concept of Spatial Augmented Reality. By using an Infrared pen with any flat surface, such as a piece of paper that receives projected images from a projector, a user is able to perform a variety of interactive visualization and manipulation in the 3D space. A number of case studies of implementation using the MagicPad framework have been presented, which include the magic lenses like interface inside a CAVE-like system, a physics game and a virtual book in an art installation.
