Web 3.0 Virtual Reality Wiki

 Welcome to the ! Virtual reality technology, also known as the spirit environment technology, is a new practical technology developed in the 20th century. Virtual reality technology includes computers, electronic information and simulation technology, and its basic realization is to simulate the virtual environment by computer, so as to give people a sense of immersion in the environment. With the continuous development of social productivity and science and technology, the demand for VR technology in all walks of life is growing. VR technology has also made great progress, and gradually become a new field of science and technology.

Introduction

The so-called virtual reality, as the name suggests, is the combination of virtual and reality. Theoretically speaking, virtual reality technology (VR) is a kind of computer simulation system that can create and experience the virtual world. It uses the computer to generate a simulation environment, so that users can immerse in the environment. Virtual reality technology is the use of real-life data, through computer technology to generate electronic signals, combined with a variety of output devices, so that it can be transformed into a phenomenon that people can feel, these phenomena can be real objects in reality, can also be our naked eye can not see the material, through the three-dimensional model. Because these phenomena are not what we can see directly, but the real world simulated by computer technology, so they are called virtual reality.

Virtual reality technology has been recognized by more and more people. Users can experience the most real feelings in the virtual reality world. The authenticity of its simulation environment is difficult to distinguish from the real world, which makes people feel immersive; At the same time, virtual reality has all the perception functions of human beings, such as auditory, visual, tactile, taste, smell and other perception systems; Finally, it has a powerful simulation system, truly realizes the human-computer interaction, so that people can operate at will in the process of operation, and get the most real feedback from the environment. It is the existence, multi perception and interaction of virtual reality technology that makes it popular with many people.

 Characteristic 

1. Immersion

Immersion is the most important feature of virtual reality technology, which enables users to become and feel part of the environment created by the computer system. The immersion of virtual reality technology depends on the user's perception system. When the user perceives the stimulation of the virtual world, including touch, taste, smell, motion perception, it will produce thinking resonance, resulting in psychological immersion, It's like going into the real world

2. Interactivity

Interactivity refers to the user's operability of objects in the simulated environment and the natural degree of feedback from the environment. The user enters the virtual space, and the corresponding technology enables the user to interact with the environment. When the user performs certain operations, the surrounding environment will also make certain reactions. If the user touches an object in the virtual space, he or she should be able to feel it in his or her hand. If the user acts on the object, the position and state of the object should also change.

3. Multisensory

Multi perception means that computer technology should have many ways of perception, such as hearing, touch, smell and so on. The ideal virtual reality technology should have the perception function of all people. Due to the limitations of related technologies, especially sensor technology, most of the perception functions of virtual reality technology are limited to vision, hearing, touch, motion and so on.

4. Conceivability

Imaginative is also called imaginative. In virtual space, users can interact with the surrounding objects, broaden the scope of cognition, and create scenes or environments that do not exist in the objective world. Conception can be understood as the user entering the virtual space, absorbing knowledge according to his own feeling and cognitive ability, expanding thinking and creating new concepts and environment.

5. Autonomy

It refers to the extent to which objects act according to the laws of physics in the virtual environment. For example, when pushed by the force, the object will move in the direction of the force, or overturn, or fall from the desktop to the ground, etc.
