The pattern of functioning of AR apps depends on their type. Commonly, every AR software has a special trigger like markers, GPS data, or certain conditions. First of all, an augmented reality app scans the scenery with camera lenses to find this trigger or turn on GPS in case of a location-based AR application. Then it places the digital visual content you selected in the place you direct the camera on. This way you can see products in their real look, get instructions and info, monitor maps, etc.
