How does Augmented Reality work?

Explanation about using Augmented Reality


Using a mobile application, a mobile phone's camera or a web camera identifies and interprets a marker, often a black and white barcode image.


The software analyses the marker and creates a virtual image overlay on the mobile phone's screen, tied to the position of the camera.


This means the app works with the camera to interpret the angles and distance the mobile phone or web camera is away from the marker.


Due to the number of calculations a phone/web camera must do to render the image or model over the marker, often only smartphones are capable of supporting augmented reality with any success.


Phones need a camera, and if the data for the AR is not stored within the app, a good 3G Internet connection.



A traditional Augmented Reality application and its basic parts are depicted in the above image and can be broken down to two steps for basic understanding, detection and overlay:


  • Detection: A camera detects a reference point(s) from which to display the Augmented Reality. This reference point can be a specific shape (a series of dots), object (great to use if your product has a unique shape) or image.

  • Overlay: A digital overlay is then correctly positioned according to the detected reference point(s). Here is where the processor-intensive aspect comes in to play the more complex the overlay, the harder the processor will have to work.
