What s virtual reality all about? Do you have any examples?

First, look at it from a different meaning.

1. Reality: that is, the explanation of objectively existing things or facts, real and immediate objects.

2. Virtual: a virtual situation that does not conform to or does not necessarily conform to the facts; Something made up by imagination.

Second, look at it from the perspective of different characteristics.

1. Reality: Objective reality = law + events that occurred in the past + specific things that existed in the past.

2. Virtual: It is not a new type of information interaction that exists in the traditional material form, such as providing network services, electronic services, and data exchange functions.

Third, look at it from the perspective of different expressions.

1. Reality: In line with the actual situation, true. A Ying's "Inscription": "Today's view of copying and carving the book, carving the characters, is extremely realistic.

2. Virtual: a virtual situation that does not conform to or does not necessarily conform to the facts; Ye Shengtao's "Sick Man": "Then there is nothing to say, and it is difficult to be virtual if you don't want to do it." ”

Virtual reality is a computer-simulated environment that simulates physical existence in both the real and imaginary worlds. Virtual reality artificially creates sensory experiences, including sight, sound, touch, and smell.

Virtual reality technologies mainly include virtual reality headsets, sometimes referred to as head-mounted displays (HMDs), that provide stereoscopic images or**, and omnidirectional treadmills, which allow users to experience virtual reality with the naked eye**. Simulated environments can resemble real-world experiences to create realistic experiences – for example, products used to train military personnel (and by extension, civilian employees). [1] Virtual reality consists of a rendering of 2D 3D graphics that is perceptually provided to the user using 3D goggles or other devices that provide stereoscopic displays.

Virtual reality replaces all physical sensations with virtual sensations, creating immersive environments that can simulate touch, taste, sight, and sound. Users can interact with objects or people in the VR environment using specially designed peripherals, such as keyboards and game controllers.

Virtual reality also refers to an immersive environment with a 2D or 3D representation of the real world that can be explored and interacted with (often using a controller). These experiences can be realistic or fantastical in nature. Some advanced haptic systems now include haptic information, often referred to as force feedback in medical, gaming, and military training applications.

Immersive environments can resemble the real world to create realistic experiences – for example, flight simulator software.

Some of the VR systems used in the game can transmit vibrations and other sensations to the player through a game controller. Virtual reality also refers to a telematics environment that provides a user's virtual presence through telepresence or the use of virtual artifacts (VAs), whether through the use of standard input devices such as keyboards and mice, or through multi-modal devices such as wired gloves or omnidirectional treadmills. Immersive environments can resemble the real world to create a realistic experience – for example, VR systems that allow surgeons to train on "touch time", allowing them to operate on patients without the need for incisions.

Computers simulate virtual environments to give people a sense of immersion in the environment.
