Supporting Workspace Awareness with Augmented Reality‐Based Multi‐camera Visualization and Tracking

A multi-camera system can consist of traditional RGB cameras or 3D cameras with depth-capturing capabilities. This chapter discusses the advantages of multi-camera remote assistance systems over more traditional systems that use one camera from the worker's perspective. It covers the design and implementation of SceneCam, a multi-camera AR system with techniques for making the helper aware of the worker in a large workspace, and CueCam, a multi-camera AR system that uses three AR awareness cues to make the worker aware of the helper's location and actions in a large workspace. The chapter also discusses proposals for improving the focus-in-context views of SceneCam with the aim of improving the workspace awareness, i.e. collaborators' awareness of each other.
