What is Augmented Reality?

You can describe Augmented Reality (AR) as a combination of reality and a visual layer of data.

To be called Augmented Reality, three things must be fulfilled:

1. The sense of mind must come from reality and digital at the same time.
2. The two worlds must match each other geometrically.
3. It should be done in real-time.

How does Augmented Reality work?

There are a number of different frameworks and programs that can be used to develop an AR application. When the AR application is launched, it will look for a marker, surface, or other references to place the AR object on. Once found, the application knows what type of information to display, such as texts, images, video or a 3D object.

The AR application can be built to function as a program in the computer, to a mobile phone or be entirely web-based and run in the computer’s browser.

Mobile AR

Many AR applications for mobile phones use the built-in GPS to display points of interest and additional data. Sometimes in combination with the phone’s camera finding a surface to place the 3D object on, an example of this is the popular game Pokémon GO. As the phones get better, it is now also possible to view 3D objects directly on the ground or use object recognition to place the augmented layer.

DING primarily works with the Vuforia framework for cursor-based AR for iOS (iPhone and iPad) and Android.

Cursor / Pattern

Many AR applications use a marker (or pattern as it is also called). The task of the cursor is to provide information to the AR application where the 3D object is to be displayed and its orientation. Therefore, to get the right orientation, the cursor image should be asymmetrical, so that the application knows what is “forward, back, up and down”. The pattern may be a flat image, but in more advanced AR applications, the application can recognize objects from, for example, a video stream.
