Augmented reality (AR) is the technology that adds virtual elements to reality, giving the users the opportunity to see a real object and to interact with it, relying on a better understanding of what is happening around them. The basic principle of operation of augmented reality is the overlay. To better explain this concept we can give an example: the camera detects the object in the scene, the system recognises it and activates a new level of communication that overlaps and perfectly integrates into reality, thus enhancing the amount of detail data in relation to that object.
DIFFERENCE BETWEEN VR AND AR
Augmented reality should not be confused with virtual reality, which consists in the construction and representation of an entirely artificial world made of virtual objects. On the contrary, augmented reality consists in a mix of real and virtual objects and can be enjoyed through various devices such as smartphones, tablets and smartglasses like HoloLens. The innovative technology of augmented reality, therefore, adds additional information generated by a computer to the normal reality perceived through our senses. This information may consist of videos, 3D animations, audio and multimedia files. Small VR headsets like immersive helmets or common smartphone cameras allow the user to enjoy many kinds of contents.
APPLICATION SCENARIOS FOR AUGMENTED REALITY
Over the years, thanks to the rapid evolution of both software and hardware, the power of digital devices has increased considerably. This has allowed an evolution of augmented-reality systems that today are used in numerous fields and provide multiple solutions, both in the workplace and in the entertainment field. Augmented reality, in fact, makes it possible to learn while enjoying, thanks to its emotional and engaging operation. Thanks to its versatility, in fact, AR can be used both in applications intended for all users, and in precision applications designed for specific professional sectors. Below some application scenarios:
