A Cable-less Interaction Device for AR and VR Environments

This paper describes the Magic Pen, a modified pen that allows natural cable-less interaction with AR environments. The pen is a normal pen with bright Light Emitting Diodes (LEDs) mounted at each end. Using computer vision techniques, these LEDs are tracked in the image captured by a head-mounted camera, and the pen’s position and orientation are computed. This permits the use of image plane interaction techniques for interacting with virtual images. We describe the computer vision algorithms used, the tracking results and the interaction supported.
