The Augmented Reality (often called AR) is used to enhance reality with virtual content: augmented reality is in fact the overlapping of layers with information (of different types such as video and graphics 2D, 3D, audio) to the real environment. The elements that add to the reality can be made through the use of various devices such as a workstation equipped with a webcam (workstation, PC, Mac), camera-equipped mobile devices (smartphones, tablets) or special viewers (smart glasses).
The camera, webcam or camera shooting the surroundings and show the augmented reality through the recognition of some target mobile or through the recognition of certain items.
The different AR currently available software rework the live video stream in real time, adding that integrate multimedia content to the context and enrich it through tracking and geolocation.
Some of the fields currently most successful are education and culture. Tourist maps, educational books can come to life showing a 3D monument reconstructed through digital anastylosis, or touristic paths can be used with new digital information that changes the classic concept of a tourist guide; information and further details may be added to the real environment to help tourists to interact with the cultural environment.
Augmented reality is also an important tool for the work of professionals such as architects, engineers, geologists, archaeologists and designers. The AR is a valuable support in assessing the impact of their projects and relationships with the buildings and surrounding spaces. Solutions for professionals have already been developed and allow you to view and interact with virtual models in places inside or outside.
It is also possible to watch a preview of any piece of furniture from the comfort of home, to assess their impact, the choice and then purchase.
