Introduction
In the previous article, we discussed the applications of virtual reality and its three main categories. In the second part of the VR technology article, we will examine 4 subcategories of VR, including Augmented Reality, Collaborative Virtual Reality, Mixed Reality, and Medical Virtual Reality.
Augmented Reality (AR)
The fourth category is a form of augmented reality. Augmented Reality (AR) allows the user to observe the real world using a device and add virtual elements to it. In this technology, virtual information is added to the real image, which can include texts, 3D shapes, images, and even interactive videos. Augmented Reality is a type of Virtual Reality where the user sees the virtual world through a phone screen and applies virtual changes to it. Augmented Reality is when an entity or specific device exists in reality but does not actually exist, and instead of immersing you in the virtual world, it places a virtual entity in the real world through any tool. A good example of it is the game Pokémon Go. This game is made in the style of Augmented Reality. In this game, you turn on your phone’s camera and aim it toward a place where you guess a Pokémon might be, and once your phone shows the Pokémon on your screen, you see it as if it were in a frame. Pokémon only appears on your display screen, and there is no physical addition to the real environment where you are filming. Another application is in the design industry for various places. Suppliers of home and office furnishings or decorators use this technology.
