Technology that allows you to preview 3D models (usually products) in “real space” utilizing the camera of your mobile device. Important distinction is to be made: there are multiple types of AR.

Marker-based, when you have to scan a mark of some sort (e.g. QR code) for the model to load, markerless – in which you only have to scan the ground that is infront of you, web-based AR, that allows you to preview 3D models online, without the necessity for downloading any mobile application, and app-based AR with which you have to download a dedicated mobile application that contains the 3D models you wish to preview.
