Using augmented snapshots for viewpoint switching and manipulation in augmented reality.

SnapAR is a magic-lens-based hand-held augmented reality application that allows its user to store snapshots of a scene and revisit them virtually at a later time. By storing a still image of the unaugmented background along with the 6DOF camera pose, this approach allows augmentations to remain dynamic and interactive. This makes it possible for the user to quickly switch between vantage points at different locations from which to view and manipulate virtual objects, without the overhead of physically traveling between those locations.
