Augmented Reality vs. Virtual Reality: A Beginner's Guide
In digital stores like IKEA, we often see furniture as 3D models in real life through phones. Similarly, in a VR game, users use glasses or headsets to interact in a virtual reality, completely different from the physical environment.
These experiences, which seem real, are made possible by Augmented Reality (AR) and Virtual Reality (VR).
Definition:
Augmented Reality(AR) is a technology which shows real time digital information, e.g. text, graphics, and animations on the real world and helps the user to interact with the information through a display.
Virtual Reality (VR) is a computer-generated simulation of a three-dimensional environment that creates a virtual world, letting users experience immersively.
Why AR and VR:
By creating an entire different world, users can experience different situations, training and environment regardless of outer reality, while using AR, users can give products virtual try and reviewing the product.AR and VR use technology to create different experiences that are more realistic and interactive.
| Feature | Augmented Reality (AR) | Virtual Reality (VR) |
| Definition | AR only overlays 3D images, making an interaction between the digital and physical worlds. | VR creates a fully virtual world, creating total immersion of the human senses |
| Interaction | AR enhances both the virtual and real world | VR only enhances a fictional reality |
| User Experience | AR users can control their presence in the real world | VR users are controlled by the system |
| Hardware | AR uses smartphones. | VR uses headset. |
AR applications:
Retail: Virtual try-ons for clothes or furniture placement previews.
Navigation: Real-time overlays on maps or directions.
Industry: Helps to do complex tasks like machinery repair or surgery guidance.
Gaming: Games like Pokémon Go, helping to show digital gameplay in real world.
VR applications:
Gaming: Fully immersive experiences with realistic environments.
Training: Simulations for pilots, military, or medical professionals.
Education: Virtual field trips or complex concept visualizations.
Therapy: Exposure therapy or relaxation environments.
How to learn to make AR and VR applications:
Select Your Application
For AR: Use Unity with AR Foundation
For iOS: use ARKit
For Android: ARCore
For VR: Use game engines e.g. Unity or Unreal Engine paired with VR SDKs like Oculus SDK or SteamVR.
Learn programming languages
For AR:
Android → Java/Kotlin
iOS→ Swift
For VR:
C++ → Unreal Engine
C# → Unity
Get Experience With Easy Projects
Learn to use the applications by watching tutorials, reading documentation, or through hands-on practice.Test your application with device
To assess user experience, test your AR apps on smartphones or VR apps on headsets.
Conclusion:
AR technology combines digital content with reality. VR creates immersive digital worlds. By affecting various industries like gaming, education, retail etc, they will soon bring new changes in our daily life, making immersive experiences a part of everyday life.
