Mobile tele-instruction using interactive augmented reality

Abstract

Augmented Reality technologies, which enable virtual object overlay on real images, are useful for interactive tele-instruction. Current advances in mobile computing and imaging technologies enabled image capture on small mobile devices (e.g., PDA's) using micro cameras. However, this imaging capability is not being efficiently leveraged, not yielding many useful applications. In this paper, an interactive mobile tele-instruction technology is described where an on-site non-expert can be instructed using graphics and text annotations created by an off-site expert. For tracking and 3D visualization, augmented reality technologies are applied. © Springer-Verlag Berlin Heidelberg 2003.
