Facebook Reality Labs is building LiveMaps, calling it "the core infrastructure that will underpin tomorrow's AR experiences." LiveMaps generates a shared, virtual map that mirrors the physical world, using machine vision, localization and crowd-sourced mapping technology. Facebook will use the oodles of data that it collects from its 2.4 billion users to build LiveMaps, pulling geotagged images to generate point clouds and create a precise virtual globe.

In Facebook's vision for AR, headsets and glasses will tap into these previously generated 3D maps, rather than reconstructing a user's actual surroundings in real-time. This enables virtual teleportation capabilities and allows assistance technology to provide information about nearby objects and locales.

LiveMaps and Facebook's AR goals are still years away from becoming mainstream consumer products, but the work is beginning now, and the company certainly has the data to back up the creation of a new, fake reality.
