Virtual reality (VR, also known as artificial reality) is a computer-generated environment that simulates a realistic experience through sensory inputs such as sight, hearing, and touch. It creates an illusion of reality by using advanced computer systems to provide visual, auditory, and tactile sensations. This technology has become widely popular and is being integrated into various fields to enhance experiences. For example, leading online platforms like Bettilt Casino utilize virtual reality technology to enrich the gaming experience for their users
Fields of use of virtual reality:
Training — simulation of complex or dangerous activities, for example, driving a vehicle, surgical operations.
Science is the visualization of the internal structure of objects, molecular and atomic structures. In particular, in medicine, virtual reality provides remote and precise control of instruments.
Design — construction and editing of three-dimensional models of mechanisms, structures, etc.; simulation and study of various effects on them.
Entertainment — virtual tours, excursions, video games with the effect of immersion in the game world
Military sphere – training of pilots, drivers, operators, units with simulation of armed clashes, etc.
How VR technology works
The most common means of immersion in virtual reality are specialized helmets / glasses. The video in 3D format is displayed on the display in front of the user’s eyes. The gyroscope and accelerometer attached to the case track head turns and transmit the data to the computer system, which changes the image on the display depending on the readings of the sensors. As a result, the user has the opportunity to “look around” inside the virtual reality and feel himself in it, as in the real world.
VR glasses are a specialized device capable of simulating various audiovisual three-dimensional spaces. It consists of a plastic (rarely cardboard) case, a screen with a partition and aspherical lenses, which focus the image. The effect of presence is created thanks to the transfer of an adaptive image to each eye separately and tracking of all head movements by the gyroscope sensor and accelerometer.
Additional equipment is used for full user interaction with virtual reality elements:
a magnetometer is a kind of compass that improves orientation in 3D space;
magnetic button — expands the user’s capabilities during the game (for example, it can serve as a trigger in shooting games or a speed booster in car races);
motion controller — allows the user to directly participate in the game and interact with objects;
remote control — allows you to control the built-in video player and significantly expands the functionality of VR glasses;
headphones – provide full “immersion” in virtual reality;
microphone — allows you to enter information by voice and communicate with other users;
external sensors of orientation in space – placed in the corners of the room for better tracking of movements in virtual reality.
How to choose VR glasses?
There are approximately 1,000 models of VR glasses on the market today, so there is plenty to choose from. According to their purpose, they are all divided into 4 types:
VR glasses for smartphones;
VR glasses for PCs and laptops;
VR glasses for game consoles;
standalone VR glasses.
Let’s consider their features in more detail.
VR glasses for smartphones
In virtual reality glasses for smartphones, the role of the screen is played by the display of the mobile device, which is inserted into the case. They are great for watching 3D movies, VR mobile games (like Minecraft, Real Racing 3, Need For Speed Shift, GTA Vice City) and 3D desktop applications.
Features:
work only with a smartphone (there are universal models – for example, VR BOX 2.0, which support most modern smartphones, and branded ones – for example, Samsung Gear VR, which are suitable for the manufacturer’s flagship models);
image quality depends on the extension and matrix of the smartphone display (respectively: the better the screen of the mobile device, the brighter the stay in virtual reality);
suitable for computer games via USB connection to PC.
Advantages:
mobile (can be taken with you on a trip or to friends at a party);
do not require a powerful personal computer;
affordable.
Advantages of using virtual reality in education:
Clearness. Any process or object can be explored in depth within a virtual space without any limitations, making it far more engaging than simply viewing images in a textbook. For instance, you could examine the human body’s structure, explore the underwater world, or even dive into a volcano. This immersive method of learning will be invaluable for studying complex processes and phenomena in STEM projects.
Concentration. In a virtual environment, a person will not be distracted by external stimuli, which will allow him to fully focus on the material.
Maximum engagement. Virtual reality technologies provide an opportunity to fully control and change the scenario of events. A student can witness historical events, conduct an experiment in physics or chemistry on his own, or solve a problem in a playful and easy-to-understand way.
Security. With the help of VR and AR technologies, you can perform a complex operation, drive a sports car or even a space shuttle, conduct an experiment with dangerous chemicals and at the same time not harm yourself or the environment.
