VIRTUAL REALITY

Virtual Reality, referred to as VR technology, also known as spiritual technology or artificial environment, is the use of computer simulation to create a three-degree space virtual world, providing users with visual, auditory, tactile and other sensory simulations, so that users can observe things in three-degree space in a timely and unrestricted manner. When the user moves the position, the computer can immediately perform complex operations to transmit accurate 3D images of the world back to create a sense of immersion.

 

This technology integrates the latest development achievements of computer graphics (CG) technology, computer simulation technology, artificial intelligence, sensing technology, display technology, and network parallel processing. Overview From a technical point of view, VR systems have the following three basic features: three “I” immersion-interaction-imagination (immersion-interaction-imagination), which emphasizes the dominant role of people in virtual systems.

From the past, people can only observe the results of processing from outside the computer system, to people can immerse themselves in the environment created by the computer system, from the past people can only work through the keyboard, mouse and single-dimensional digital information in the computing environment, to people can interact with multiple sensors; from the past can only be inspired by quantitative calculations to deepen the understanding of things, to people It is possible to derive perceptual and rational insights from a qualitatively and quantitatively integrated environment to deepen concepts and embrace new ideas. In short, in future virtual systems, people aim to make this information processing system made up of computers and other sensors “meet” people's needs as much as possible, rather than forcing people to “coincide” with those less intimate computer systems.

 

Most of the virtual reality technologies are visual experiences, typically from computer screens, special displays, or stereo displays, but some simulations include other sensory processing, such as sound effects from sound and headphones. Some advanced tactile systems also contain tactile information, also called force feedback, which is used in medicine and games. People interact with the virtual environment either by using standard devices such as a keyboard and mouse, by simulating devices such as a wired glove, or by situational arm and/or omnibus bike. Virtual environments can be similar to the real world, such as flight simulation and combat training, and can be significantly different from the real world, such as virtual reality games. In current realities, it is difficult to create a highly realistic virtual reality environment, mainly due to technical constraints arising from computer processing capabilities, image resolution and communication bandwidth. However, as processor, image and data communication technologies become more powerful and cost-effective over time, these constraints will eventually be overcome.
