MagicPad: the projection based 3D user interface

摘要

In this paper we describe a novel design and implementation of a tangible user interface framework, namely the MagicPad. The MagicPad is inspired by the concept of Spatially Augmented Reality. By using a wireless 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. The result of the user test is then presented and finally we suggest the possibilities of improving the Magic- Pad by using a pico projector to replace the wireless pen.
