What is the difference between AR and VR?

Augmented Reality (AR) enables users to interact with their physical world via their mobile device camera and display.  This technology adds a layer of content on the device screen whilst still enabling users to see the real world through their phone camera.

Virtual Reality (VR) enables users to interact with a virtual world via a specialized head-mounted display or headsets.  This technology places users in a completely immersive experience that shuts them out of the physical world.
