What is virtual reality and examples?

Virtual reality or VR is a technology that creates a virtual environment. People interact in these environments using, for example, virtual reality glasses or other mobile devices. Virtual reality (VR) is a simulated experience that can be similar or completely different from the real world. Virtual reality applications include entertainment (especially video games), education (such as medical or military training), and business (such as virtual meetings).

Different types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR. This prototype, built on a shell of another virtual reality headset, was only capable of rotational tracking. It can be used to provide students with a virtual environment in which they can develop their skills without the consequences of failure in the real world. The English translation of this book, published in 1958 as El teatro y su doble, is the first published use of the term virtual reality.

Simulated reality is a hypothetical virtual reality that is as immersive as real reality, allowing for an advanced realistic experience or even a virtual eternity. Many modern first-person video games can be used as an example, using various triggers, responsive characters, and other similar interactive devices to make the user feel as if they are in a virtual world. Virtual reality (VR), the use of computer modeling and simulation that allows a person to interact with a three-dimensional (3D) artificial visual environment or other sensory environment. This hybrid technology allows, for example, to see virtual objects in the real world and build an experience in which the physical and the digital are practically indistinguishable.

AR systems place virtual information through the live broadcast of a camera on a headset or smart glasses or through a mobile device, giving the user the ability to view three-dimensional images. The hardware supports sensory stimulation and simulation, such as sounds, touch, smell, or heat intensity, while the software creates the rendered virtual environment. In projector-based virtual reality, modeling the real environment plays a vital role in several virtual reality applications, such as robot navigation, construction modeling, and aircraft simulation. By wearing data gloves equipped with force feedback devices that provide the sensation of touch, the user can even pick up and manipulate the objects he sees in the virtual environment.

You can participate in the virtual environment distributed in 3D as a conventional avatar or a real video. The original LEEP system was redesigned for NASA's Ames Research Center in 1985 for its first virtual reality installation, Scott Fisher's VIEW (Virtual Interactive Environment Workstation). Mixed reality (MR) is the fusion of the real world and virtual worlds to produce new environments and visualizations in which physical and digital objects coexist and interact in real time.
