Three-dimensional interactive pen based on Augmented Reality

In order to shorten the learning curve and simplify the complex in current CAD system, one direct approach is to provide a more intuitive way of interaction. This paper proposes an interactive pen tool, which transforms the actions in real space into the virtual three-dimensional CAD system space. Augmented Reality technology is used to track the operator's action in the real world. The design and principle of the interactive tool are introduced in detail. In addition, the experimental system is provided to illustrate a simple process of curves designing and the statistics result of tracking error is also given.
