Virtual Reality Vs. Augmented Reality In The Military

2. What is VR? What is VR not?

The definition of virtual reality comes from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’.

2 .1 In technical terms…

Technically Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be examined and interacted with by a person. That person becomes part of this virtual world or is deeply involved with this environment and at the same time, is able to manipulate objects or perform a series of actions.

2.2 What’s the difference Between Virtual Reality and Augmented Reality?

Virtual Reality and Augmented reality

Here is a list of the many applications of virtual reality:

2.3.1 Virtual Reality in the Military

Military adopts Virtual reality for all three services army, navy and air force where it is used for training purposes. This is useful for training soldiers for fighting or other dangerous situations where they have to learn how to react to a particular situation.

In a virtual reality simulation there is no risk of death or a serious injury. They can re do a particular act, where they can be involved with the enemy in an environment without the real world risks. This has proven to be safer and less costly than traditional training methods.

2.3.2 Virtual Reality and Education

In Education, virtual reality is being increasingly used for teaching and learning situations. This allows a large group of students to interact with each other. For example, Solar Systems can be learnt by astronomy students and they can also understand how it works by physical engagement with the objects within. Planets can be moved, stars can be seen and a comet can also be tracked. This can help them to see how abstract concepts work in a three dimensional environment which makes them easier to understand and

Here surgery is performed by means of robotic device controlled by a human surgeon, which reduces time and risk of complications. Virtual reality has been also been used for training purposes. In the field of remote telesurgery also virtual reality is used in which surgery is performed by the surgeon at a separate location to the patient.

2.3.4 Virtual Reality in Entertainment

The entertainment industry is one of the most excited promotion of virtual reality, mostly in games and virtual worlds. But other equally popular areas include

• Galleries

• Theatre, e.g. interactive performances

• Virtual theme parks

• Discovery centres

2.3.5 Virtual Reality in Fashion

Virtual reality is used by the fashion industry in a variety of ways. These include:

• VR software for building virtual fashion stores

2.3.6 Virtual Reality in Business

In a number of ways virtual reality is used by the business community which include:
