The Booming Realities (AR/VR)

Today we are going to see one of the most trending topics in technology, Augmented Reality and Virtual Reality. Let’s hop into it now!

Augmented Reality (AR):

Augmented Reality is a programming system such that the user cannot distinguish between original traits and virtual traits. AR is the trending technology that is used in every field. Many prominent firms like Instagram, Snapchat, etc use AR. The application of AR is used in various fields such as Engineering Design, Robotics, Manufacturing, and Military training.

Augmented Reality is also used to make anime, face models using face mesh, and many filters. It is a real-time entity that has been altered by computer-generated graphics/ animations to bring them into the real world.

Many companies are using AR, like catching Pokémons in Pokémon Go, visualising how IKEA furniture fits into our room atmosphere, fitting or selecting glasses on our face by Lenskart. Many more companies are expanding their infrastructure in Augmented Reality. This can be achieved by adding multiple layers of digital information into real-time work.

How does Augmented Reality work?

AR works by adding an array of data like images, videos, animations, 3-D models; these will result in improving both natural and synthetic layers of digital data in the real world. AR can be deployed in many electronic devices like mobiles, laptops, Smart TVs, and even smartwatches. Augmented Technology involves highly advanced technologies like SLAM (Simultaneous Localization and Mapping) and Depth Tracking. Depth Tracking involves sensors that calculate the distance and time of an object.

AR understands the environment around the user and it works according to the given patches; like changing the colour of your eye when you blink. This works with the patches present in the AR studio library. The computer vision captures the raw data (face cuts, surroundings, image, and video) of the user and it adds multiple layers to the digital process. The rendering modules in the AR Studio augment the reality and processes it into the digital framework and creates an augmented environment.

Applications of AR:

  1. Classroom Education
  2. Business Analytics
  3. Virtual Tourism
  4. Modelling and Designing
  5. Maintenance and Repair
  6. App and Game Development

Virtual Reality (VR):

The term Virtual Reality has a very broad definition. Many people would think of VR as computer-generated services like net banking, online transactions, etc. Others think of it as computer-generated graphics used in games, films, theatres, etc. So what is VR?

Fred Books defined that VR as an experience in which “the user is effectively immersed in a responsive world.” But what does a responsive world mean?

VR is a three-dimensional computer-generated virtual environment where a person is free to explore it. VR could be considered as a pathway to the virtual environment.

What differentiates VR from other media?

  • 3D Stereovision: A VR box has two displays, similar to a human. A human has two eyes to enable vision. The first eye has a different display when compared to the second eye (There is a slight change in the angle of vision). A VR box works on the same principle and hence it is said to have 3D stereovision.
  • User Dynamic Control System: VR provides user dynamic control, meaning the user can have a more realistic experience when compared to 3D cinema. The view or display is updated to the viewpoint of that specific user. Head-mounted display or HMD is a technology used to achieve this.
  • Surrounding Experience: The surrounding experience defines the realistic virtual nature where the user is trapped. Consider yourself sitting in a theatre. Along with you, there are several people in the same theatre. As your eyes view the movie, when you turn around you will see the people around you. But when using VR, you will be still trapped in that realistic Virtual Environment.

Technologies crucial for Virtual Reality:

  • Visual Display — An area in which the user is immersed in the virtual world. There are two types of display Head-mounted display (HMD) and CAVE (Cave Automatic virtual environment)
  • Graphic System — Generates images for the Virtual Reality
  • Tracking System– A system reporting the position and orientation of the user’s head
  • Database construction system — Building realistic and immersive model of the virtual world

Virtual Reality mimics the Real-world and allows you to:

  1. Walk-in a three-dimensional space
  2. Play multi-player games
  3. Performing Virtual operations

Applications of Virtual-Reality:

1. Healthcare Industries:– To become a specialist, a healthcare employee requires working and experiencing various situations before working on actual patients. VR has helped healthcare professionals to practice with virtual bodies before working with patients.

2. Tourism:– We all know about the heavy expenses and planning that goes on before booking a tour. Tourism launched its first VR in 2015 under the motto ‘Try before you fly”. This helps people experience and book the best choice according to their needs.

Some other applications include real estate, entertainment, etc.

There are many other applications in both AR and VR. Technology is an ocean where we just explored the shore. There is a lot more to find out!
