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.
