What is Augmented Reality (AR):

Augmented Reality (AR) is a technology that expands the physical world by adding the digital information layers onto it. AR does not create virtual environments to replace the real environment it emerges in a direct view of an existing environment and adds sounds, videos, graphics to it. AR is the view of the real physical world environment with computer-generated images, that transforming the perception of reality, and in which we can see the physical environment right in front of us such as dogs catching balls, trees moving in the park, kids playing the soccer game with a digital augmentation overlaid on it.

How Augmented Reality works:

In AE, a certain amount of data in the form of animations, images videos, and 3D models may be used, and people will get the outcome in both synthetic and natural lights. Also, people are conscious of being in the physical world that is advanced by using computer vision, unlike in VR. Augmented reality can be shown on different devices such as screens, mobile phones, glasses, head-mounted displays, and handheld devices. It includes immersive technologies such as S.L.A.M. (simultaneous localization and mapping) and the following components:

Depth tracking

A sensor that calculates the data of distance to the objects.

Capturing module

This module captures an image from the camera.

Tracking module

 It calculates the orientation and correct location for the virtual overlay.

Rendering module

It combines the virtual components, original image, and renders the AR image on the display.

Types of Augmented Reality:

Marker-based AR

Marker-based also known as image recognition, as it needs a camera and a special visual object to scan it. It might be something, from a special sign to a printed QR code. The AR device can also compute the orientation and position of a marker to place the content. Thus, a marker starts the digital animations for people to view, and so pictures in a magazine can turn into augmented 3D models.

Markerless Augmented Reality

Markerless includes position-based or location-based augmented reality, that uses a compass, a GPS, an accelerometer, and a gyroscope to deliver data built on the user location. These statistics then determines what type of Augmented Reality content you get in a certain area location. This kind of Augmented Reality produces maps and directions, with the availability of smartphones. Their applications contain navigation support, events, and information, and business ads pop-ups.

Projection-based Augmented Reality

Projection-based AR detects user communication with a projection by its alterations. It allows us to interact with physical surfaces and Projecting synthetic light to it. These are the holograms we have seen in sci-fi movies like Star Wars.

Superimposition-based Augmented Reality

It changes the original physical view with AR partially or completely. Object recognition performs an important role, without it the entire concept is just impossible. We have seen many examples of augmented reality such as the IKEA app, that permits users to place computer-generated objects of their given furniture catalog in their physical rooms.

Augmented Reality SDKs:

The SDKs and plugins that are used to develop AR applications are followings:

Wikitude AR SDK:

The Wikitude SDK is a framework and software library for the mobile application that used to create immersive AR experiences. This SDK supports location-based use cases and use cases that need tracking technology, vision-based augmented reality, and image recognition.

Kudan AR SDK:

Kudan AR SDK can be used for markerless or marker location and tracking requirements. This high-speed SDK is compatible with iOS and Android as well as providing Unity plugins with small data size and footprint. Kudan does not need the latest mobile phones due to the hardware-agnostic system.

Vuforia SDK:

Vuforia SDK is a commonly used platform to develop AR applications, provide support for tablets, eyewear, and phones. Creators can add innovative computer vision functions to iOS and Android applications, to generate AR experiences in which they can interact with augmented objects and the environment.


Google’s platform ARCore is used to create different augmented reality experiences. ARCore enables your phone to understand the world, sense its environment, and interact with information by using different APIs. Some of the APIs are available across iOS and Android to enable shared AR experiences.

Augmented Reality Devices:

Mobile devices:

Tablets and smartphones are the best fit and the most available for AR mobile applications, that ranges from entertainment and gaming to sports, and social networking.

Special AR devices:

These devices are specially designed for AR experiences. One example is head-up displays (HUD), which send data to a transparent exhibit directly into the user view. These devices created to train armed fighters’ pilots. Nowadays these devices have applications in the automotive industry, aviation, sports, and manufacturing, etc.

Applications of Augmented Reality :

AR completes our everyday activities in several ways. There are many applications some are discussed here.


One of the most popular applications of AR is gaming. These AR games provide much better experiences to players, some even help a more active outgoing way of life. Gaming is being moved from virtual and digital word to real life, and players perform many activities. AR dragon and Pokémon Go are some of the gaming examples.

Augmented Reality in retail:

AR in the retail industry bring better customer retention and engagement, brand awareness, and sales ads. These features help customers make wiser purchases that provide product information with 3D models of any color and size. 

Real estate:

The real estate can also benefit from Augmented Reality by providing 3D tours of apartments and houses.


In education, AR provides interactive models for training and learning purposes, from chemistry to mathematics.

Medicine and Healthcare:

Augmented Reality applications can used to help diagnose, monitor, train, localize the disease.


AR applications are available for advanced navigation and marking the objects in real-time.


In tourism, AR can help with sightseeing objects, directions, and navigation.
