Efficient In-Situ Creation of Augmented Reality Tutorials

With increasing complexity of system maintenance there is an increased need for efficient tutorials that support easy understanding of the individual steps and efficient visualization at the operation site. This can be achieved through augmented reality, where users observe computer generated 3D content that is spatially consistent with their surroundings. However, generating such tutorials is a tedious process, as they have to be prepared from scratch in a time consuming process. An intuitive interface that allows users to easily place annotations and models could help reduce the complexity of this task. In this paper, we discuss the design of an interface for efficient creation of 3D aligned annotations on a handheld device. We also show how our method could improve the collaboration between a local user and a remote expert in a remote support scenario.
