Abstract
Spatial Augmented Reality (SAR) systems can be used to convey guidance in a physical task from a remote expert. Sometimes that remote expert is provided with a single camera view of the workspace but, if they are given a live captured 3D model and can freely control their point of view, the local worker needs to know what the remote expert can see. We present three new SAR techniques, Composite Wedge, Vector Boxes, and Eyelight, for visualizing off-surface 3D viewpoints and supporting the required workspace awareness. Our study showed that the Composite Wedge cue was best for providing location awareness, and the Eyelight cue was best for providing visibility map awareness.
