Training and assistance to maintenance in an augmented reality environment

The background of this paper is an industrial environment, where complex mechanical tasks have to be performed. In this context, for instance power plants or aircraft manufacturers, maintenance tasks require either a lot of documentation and training or a big amount of experience. No matter, if documentation is available in paper form or in electronic form, e.g. on a laptop, the worker cannot simply focus on his work, but has to concentrate on the separated documentation as well. This paper presents the concept of a system, using Augmented Reality for an enhanced 3D workspace, which integrates the documentation and further help into user.s environment and especially in his view. Interaction with the system is performed in a multi-modal way, combining speech and a virtual pointing device
