Virtual and Augmented reality – Virtual and Augmented in 2025?

Virtual reality (VR) is a computer-generated world that can be accessed using immersive devices such as helmets, gloves, and headphones. The virtual environment completely replaces the real world without reacting to its changes, while the user can influence it by immersing himself, for example, in a video game. That is, people can still interact with the physical environment by getting additional information from their augmented reality devices or applications. This is a visualization method that connects spatial perception to traditional sources of information.

In other words:

Virtual Reality (VR) are simulations created using virtual reality helmets. The difference from augmented reality (AR) is that real objects completely disappear from view, you see only a virtual environment.

Virtual reality technology is as follows: there are two small monitors in front of your eyes, the picture on them reacts to head turns and / or movements in space as if you were seeing real objects.

How can VR helmets differ from each other:

The need for additional equipment. There are helmets that require connection to a computer, they are also called PC headsets. There are stand-alone helmets, in which all the “iron” is placed inside the helmet. Supported graphics level. The weaker the hardware, the lower the level of graphics. Standalone helmets use compact mobile chips, so the level of graphics is lower. In PC headsets, the available graphics level is higher.

The number of degrees of freedom:

Now there are two standards on the market: 3 degrees of freedom (3DoF), in such helmets the turns and rotation of the head are tracked, but not the movement of the legs. 6 degrees of freedom (6DoF) – in such helmets, the virtual space reacts not only to rotation, but also to the movement of the head in space.

Using augmented reality (AR), we look at the world not directly, but through some kind of “filter” that embeds virtual objects into the real world as if they really are there. Unlike virtual reality, the real world does not go out of sight, but is “completed”, which is reflected in the term.

Most often, a smartphone or tablet is used as a “filter” for AR. The areas of application are very different. Can be used in education, games, navigation, art, advertising, museums, events, retail.

A less common method is AR on large screens: usually used in shopping malls, at bus stops as part of advertising campaigns, etc. An even rarer, but well-known futuristic method is augmented reality glasses. They are used mainly in production, in ordinary life you most likely will not meet them. At least not today.

Education:

Virtual reality makes it possible to effectively train employees in interaction with clients and colleagues, business processes, and study the operation of complex equipment.

 Industry:

Virtual reality are now widely used in industries (staff training and simulation are the main applications of it). Your customers will be able not only to see future objects with their own eyes, but also to interact with objects inside apartments, add their own interior items, change the visual style of the interior. For built objects, an inexpensive solution with 360 video is perfect, which allows a person to see the object ready for occupancy with his own eyes.
