When discussing Mobile Augmented Reality, I find that people are often mystified by how it works, or perhaps they are familiar with QR Codes and presume Mobile AR requires similar tagging. Though tag driven AR can be implemented in mobile devices, what I'm focusing on here is place-aware augmentation. I've created this video as a simple explanation, for a non-technical audience, to demystify the technology.

Also, the visual shown is not any specific AR application, it is only meant to be a general representation of the underlying technology.

Location Aware, Mobile Augmented Reality is a rapidly-trending technology in mobile computing. I have put together this video in order to demystify the underlying technologies.

The convergence of 5 basic components make mobile AR apps possible.

Global Positioning technology allows the device to know its location on the earth. An internal compass determines which direction the device is facing. And an internal accelerometer is able to calculate the angle that the device is being tilted at.

The combination of these three technologies used in conjunction tells the device precisely where its camera is looking at any given time. When data is associated with a given coordinate, it knows to superimpose that data over the field of vision in the video display.

In this example, the device has no specific knowledge that it is looking at Philip Johnson's Glass House, per se. Only that when the G P S, Compass and Level tell it that a given position has come into the camera's field of view, specific data should be shown.
