What is Augmented Reality?

Augmented Reality (AR) is a perfect blend of the digital world and the physical elements to create an artificial environment. Apps which are developed using AR technology for mobile or desktop to blend digital components into the real world. The full form of AR is Augment Reality.

Example: AR technology helps to display score overlays on telecasted sports games and pop out 3D photos, text messages, and emails.

In this tutorial, you will learn:

What is Virtual Reality?

Virtual Reality (VR) is a computer-generated simulation of an alternate world or reality. It is used in 3D movies and video games. It helps to create simulations similar to the real world and "immerse" the viewer using computers and sensory devices like headsets and gloves.

Apart from games and entertainment, virtual reality is also used for training, education, and science. The full form of VR is Virtual reality

How does AR works?

AR uses computer vision, mapping as well as depth tracking in order to show appropriate content to the user. This functionality allows cameras to collect, send, and process data to show digital content appropriate to what any user is looking at.

In Augmented reality, the user's physical environment is enhanced with contextually relevant digital content in real-time. You can experience (AR) augmented reality with a smartphone or with special hardware.

How does VR works?

The focus of virtual reality is on simulating the vision. The user needs to put VR headset screen in front of his/her eyes. Therefore, eliminating any interaction with the real world. In VR, two lenses are placed between the screen. User needs to adjust eyes based on individual movement of eye and it's positioning. The visuals on the screen can be rendered by using a HDMI cable connected to PC or mobile phone.

Uses goggles, speakers, and sometimes handheld wearables to simulate a real-world experience. In virtual reality, you can also employ visual, auditory, and haptic (touch) stimulation, so the constructed reality is immersive.

Difference between Augmented Reality and Virtual Reality

Here, are important differences between Augmented Reality vs. Virtual Reality

AR VR
The system augments the real-world scene Completely immersive virtual environment
In AR User always have a sense of presence in the real world In VR, visual senses are under control of the system
AR is 25% virtual and 75% real VR is 75% virtual and 25% real
This technology partially immerses the user into the action This technology fully immerses the user into the action
AR requires upwards of 100 Mbps bandwidth VR requires at least a 50 Mbps connection
No AR headset is needed. Some VR headset device is needed.
With AR, end-users are still in touch with the real world while interacting with virtual objects nearer to them. By using VR technology, VR user is isolated from the real world and immerses himself in a completely fictional world.
It is used to enhance both real and virtual worlds. It is used to enhance fictional reality for the gaming world.

Advantages of Augmented Reality

Here, are pros/benefits of augmented reality

  • Offers individualized learning
  • Fostering the learning process
  • Wide variety of fields
  • Offers innovation and continuous improvement
  • Increase accuracy
  • Augmented reality can be used to increase user knowledge and information.
  • People can share experiences over long distances.
  • Helps developers to build games that offer "real" experience to the user.

Advantages of Virtual Reality

Here, are pros/benefits of virtual reality:

  • Immersive learning
  • Create an interactive environment
  • Increase work capabilities
  • Offer convenience
  • One of the most important advantages of VR is that it helps you to create a realistic world so that the user can explore the world.
  • Virtual reality in the education field makes education more easy and comfortable.
  • Virtual reality allows users to experiment with an artificial environment.

Disadvantage of Augmented Reality

Here, are cons/drawback of Augmented Reality

  • It is very expensive to implement and develop AR technology-based projects and to maintain it.
  • Lack of privacy is a major drawback of AR.
  • The low-performance level of AR devices is a major drawback that can arise during the testing phase.
  • Augmented reality can cause mental health issues.
  • Lack of security may affect the overall augmented reality principle.
  • Extreme engagement with AR technology can lead to major healthcare issues such as eye problems and obesity etc.

Disadvantages of Virtual Reality

Here, are cons/drawbacks of virtual reality

  • VR is becoming much more common, but programmers will never able to interact with virtual environments.
  • The escapism is commonplace among those that use VR environments, and people start living in the virtual world instead of dealing with real-world issues.
  • Training with a VR environment never has the same result as training and working in the real world. This means if somebody done well with simulated tasks in a VR environment, there is still no guarantee that a person doing well in the real world.

Where is Augmented reality used?

Here, are an important applications of AR technology:

  • AR apps are being developed which embed text, images, videos, etc.
  • Printing and advertising industries are using AR technology apps to display digital content on top of real-world magazines.
  • AR technology allows you for the development of translation apps that helps you to interpret the text in other languages for you.
  • With the help of the Unity 3d Engine tool, AR is being used to develop real-time 3D Games.

Where is Virtual Reality used?

Here, are an important applications of Virtual Reality:

  • VR technology is used to build and enhance a fictional reality for the gaming world.
  • VR can use by the military for flight simulations, battlefield simulations, etc.
  • VR is used as a digital training device in many sports and to help to measure a sports person's performance and analyse their techniques.
  • It is also becoming a primary method for treating post-traumatic stress.
  • Using VR devices such as Google Cardboard, HTC Vive, Oculus Rift, or users can be transported into real-world and imagined environments like squawking penguin colony or even the back of a dragon.
  • VR technology offers a safe environment for patients to come into contact with things they fear.
  • Medical students use VR to practice and procedures
  • Virtual patients are used to helps students to develop skills that can later be applied in the real world.

How AR and VR work together?

It will be wrong to convey that AR and VR are intended to operate separately. They mostly blended together to generate an improved engaging experience when these technologies are merged together to transport the user to the fictitious world by giving a new dimension of interaction between real and virtual world.

KEY DIFFERENCES:

  • AR augments the real-world scene whereas VR creates completely immersive virtual environments.
  • AR is 25% virtual and 75% real while VR is 75% virtual and 25% real.
  • In AR no headset is needed on the other hand in VR, you need headset device.
  • With AR, end-users are still in touch with the real world while interacting with virtual objects nearer to them, but by using VR technology, VR user is isolated from the real world and immerses himself in a completely fictional world.
