Case study

Augmented reality is a virtual content that overlayed on a real material. There are few ways for it to detect the augmented reality QR codes, marker, or real life project. It also able to detect by location based like GPS and Compass. Here's some augmented app such as Metaio, Layar, Junaio and etc.

There are 2 choices of tracking in unity 3D, Vuforia tracking and string tracking. Vuforia tracking tracks image target, frame markers and simple 3D object like boxes. It is more flexible than the string tracking because string tracking tracks any png and full marker of 85% camera and it is hard to scale. Vuforia can work if only part of markers is seen and it is easy to scale. However, string is can detect faster than Vuforia. Next, Vuforia is a free is free and available in IOS and Android while String is expensive and only available in IOS licensing. For my case, I will use Vuforia because it’s free and available in Android and IOS. By using Vuforia, first I need to download the library and add it into my Unity 3D project.
