Augmented Reality (AR) Vs Virtual Reality (VR) 

Augmented Reality (AR) Vs Virtual Reality (VR) 

Augmented reality is an interactive experience that combines the real world and computer-generated content. Augmented reality is made up of the word “augment” which means to make something great by adding something to it. So basically, augmented reality is a method by which we can alter our real world by adding some digital elements to it. This is done by superimposing a digital image on the person’s current view thus it enhances the experience of reality.  

Augmented reality (AR) is the integration of digital information with the user’s environment in Real Time. Unlike virtual reality (VR), which creates a totally artificial environment, AR users experience a real-world environment with generated perceptual information overlaid on top of it. 

Virtual Reality (VR) 
Virtual reality is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business. 



    • AR can be used in mobile apps to display information about landmarks when you point your phone’s camera at them. 

    • VR is often used in gaming, simulations, or virtual tours where users can explore and interact with a digital world. 

    • Snapchat uses AR technology to apply interactive filters to users’ faces in real-time. These filters can include animations, masks, and effects that augment the user’s appearance, making for fun and engaging social interactions. 

    • Google Maps integrates AR to provide users with real-time navigation guidance through their smartphone cameras. Users can see directional arrows and labels overlaid onto the real world, helping them navigate unfamiliar environments more easily. 

    • In Pokémon GO, AR is used to overlay Pokémon onto the real-world environment captured by the player’s smartphone camera. This allows players to see Pokémon appear as if they are actually present in the physical world around them. It adds an extra layer of immersion to the game, making the Pokémon-catching experience more lifelike and engaging. 

Some Differences  


    • Virtual Reality creates a fully immersive digital environment or experience that simulates the real world or imaginary world. 

    • Augmented Reality overlays digital information into the real world. 

    • It generally requires a headset or a similar kind of device to immerse the user into the digital world. 

    • It can be accomplished through smartphones or tablets with the help of AR apps. 

Different Industries where we can see Usages of AR and VR technologies 

AR enhances manufacturing processes by providing real-time data visualization, facilitating data-driven decisions, and promoting collaboration. 

VR is utilized by automotive companies like Honda, BMW, and Jaguar Land Rover for design and engineering reviews, reducing the need for physical prototypes and saving time and resources.

AR gaming, exemplified by Pokémon GO, combines virtual and real-world environments for an immersive experience. 

VR gaming offers a fully immersive experience, enhancing traditional gaming and bringing entertainment beyond smartphones. 


AR tools like Third Eye X2 smart glasses enhance traditional teaching by providing immersive experiences and facilitating remote learning. 

VR revolutionizes education by offering immersive and experiential learning opportunities, democratizing access to education worldwide. 

These technologies have diverse applications across manufacturing, healthcare, gaming, and education, contributing to enhanced experiences and improved processes.

Everything about Kotlin

Kotlin Programming: 

Kotlin is a modern but already mature programming language designed to make developers happier. It’s concise, safe, interoperable with Java and other languages, and provides many ways to reuse code between multiple platforms for productive programming. 

By using Kotlin Programming we can prepare: 

  •  Backend app 
  •  Cross-platform mobile app 
  •  Android app 
  •  Multiplatform library 

In Kotlin: 

* fun is used to declare a function 

* the main() function is where your program starts from 

* the body of a function is written within curly braces {} 

* println() and print() functions print their arguments to standard output 


All programs need to be able to store data, and variables help you to do just that. In Kotlin, you can declare: 

* read-only variables with val 

* Mutable variables with var 

* To assign a value, use the assignment operator = 

Kotlin Multiplatform: 

The Kotlin Multiplatform technology is designed to simplify the development of cross-platform projects. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility and benefits of native programming. 

Sharing code between mobile platforms is a major Kotlin Multiplatform use case. With Kotlin Multiplatform, you can build cross-platform mobile applications that share code between Android and iOS projects to implement networking, data storage and data validation, analytics, computations, and other application logic. 

Kotlin Multiplatform is also helpful for library authors. You can create a multiplatform library with common code and its platform-specific implementations for JVM, web, and native platforms. Once published, a multiplatform library can be used as a dependency in other cross-platform projects. 

Kotlin Multiplatform allows you to maintain a single codebase of the application logic for different platforms. You also get advantages of native programming, including great performance and full access to platform SDKs. 

Kotlin is a great fit for developing server-side applications. It allows you to write concise and expressive code while maintaining full compatibility with existing Java-based technology stacks, all with a smooth learning curve: Expressiveness, Scalability, Interoperability, Migration, Tooling, Learning Curve. 

Kotlin for Android :  

  • Less code combined with greater readability 
  • Fewer common errors 
  • Kotlin support in Jetpack libraries 
  • Support for multiplatform development 
  • Mature language and environment 
  • Interoperability with Java 
  • Big community 
  • Easy learning 

Learning Kotlin :  

Kotlin is easy to learn, especially for those who already know Java. A short introduction to the basic syntax of Kotlin for software developers can be found directly in the reference section of the website starting from basic syntax. 

IDEA has built-in Java-to-Kotlin converter. It can be used by people familiar with Java to learn the corresponding Kotlin syntactic constructions, but it is not perfect, and it is still worth familiarizing yourself with Kotlin and learning the Kotlin idioms. 

A great resource to study Kotlin syntax and API of the Kotlin standard library are Kotlin Koans. 

IDEs for Kotlin development 

JetBrains provides the official Kotlin plugin for IntelliJ IDEA, JetBrains Fleet, and Android Studio

Other IDEs and code editors, such as Eclipse, Visual Studio Code, and Atom, have Kotlin community-supported plugins.

Python is a high-level, interpreted, and general-purpose dynamic programming language that focuses on code readability. It was created by Guido van Rossum and released in 1991. Python’s design philosophy emphasizes code readability with the use of significant indentation. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented, and functional programming. Python is dynamically typed and garbage-collected. 

Python is popular for its simple syntax similar to the English language, which allows developers to write programs with fewer lines than some other programming languages. Python runs on an interpreter system, meaning that code can be executed as soon as it is written, which makes prototyping very quick. Python can be used on a server to create web applications, alongside software to create workflows, connect to database systems, handle big data, perform complex mathematics, and for rapid prototyping or production-ready software development.
