RemoteBob: Support of On-site Workers via a Telepresence Remote Expert System

Giving expert advice to workers from a remote location is a valuable ability. Giving expert advice effectively and precisely is even more valuable. This paper describes a possible solution for the support of on-site workers by remote experts during non-routine maintenance tasks. The approach brings the collaboration between on-site workers and remote experts to the next level: we do not only capture the on-site situation and visualize it for remote experts, but also enable experts to provide instructions via annotations and 3D-objects which are overlaid onto the on-site workers' screen. These objects are drawn and placed with a mouse cursor, or more intuitively through gesture input.
