SUBJECT: Expanded Definition of Virtual
The purpose of this document is to elaborate on the word I pick for the expanded definition project. I picked three words at the beginning, virtual, network and space. The term Network is kind of a new word, it doesn’t have that much history than the other two terms. I can not get enough information for the expanding project. For the term space, we know it is a big prerequisite for everything to work normally, computer systems are no exception. But the term space is an old word and has various meanings in different areas. It can represent time, the universe, etc. Though it has such various meanings, the term virtual is more related to my major computer information system, and it is also more representative in the computer field, which means it is more close to a special word for a specific area. At least people now heard the term virtual will associated with computer stuff immediately. The term space is not only used in academic fields, we also use it in our daily life. That’s why I chose the term virtual instead of space. The term virtual has been clearly pointed out to the “virtual technology” in the past few years. As new technology in these years, virtual technology is relatively mature than others and there is considerable room for development, no matter the technology itself or in the applied fields.
The origin of the term “virtual” is borrowed from Latin and has a long history we can look back on. There are a lot of meanings of “ virtual”. At first, it represented “Inherently powerful or effective owing to particular natural qualities” in “See if the Virtuall Heat of the Wine, or Strong Waters will not mature it.” from Sylva sylvarum. Most of the Other definitions at first also related to power. However, they were Obsoleted because it is no longer in line with usage habits or we can say it was too far away from how we use the term now. When people talk about virtual, it mainly means a kind of technology. In Proc. Eastern’s Joint Computer Conf actually used the term virtual at a description “The sole function of the virtual memory is to increase machine speed”, which we can conclude it “being on or simulated on a computer or computer network.”
In the article “Virtual reality environment using a dome screen for procedural pain in young children during intravenous placement: A pilot randomized controlled trial ” there is a description using the term virtual. It stated, “Virtual reality (VR), often referred to as a virtual environment, is a computer technology that enables users to view or ‘immerse’ themselves in an alternate world, and it is attracting attention as a digital distraction technique”. in this statement, the term virtual had been clearly defined as a kind of computer technology. The term virtual inherently carries a fake meaning, it presents something that does not truly exist in reality. That’s why the article used the statement “immerse’ themselves in an alternate world”, a world built by a computer that can not physically touch it. And just like what I stated in the definition section, the term virtual has totally different meanings in the past. Based on P. Miller’s Gardeners & Florists Dict, we can find the used the term virtual in a sentence that “the virtual Qualities of the Sun and Air, [vapours] are formed into Clouds.” In this situation, we can consider that virtual is an inherent power of nature. In the 1700s, the secret of nature had not yet deciphered. The science ability in that age was not enough to figure out the physical principle so it is suitable to use the word virtual to present something powerful while unreachable.
Obviously, in the computer information system field, the term virtual is the name of a kind of computer technology. From the past till now, virtual always carries the meaning of fake and out of understanding in the past, and artificially created, non-physical existing in modern science. Virtual is a technology with a lot of possibilities in various areas and it has a big room to develop. In industry and the medical field, it can provide a safer and more efficient environment for users’ training. In-game areas, it brings a totally new experience to gamers and a new direction to game makers, same for other art areas. So I will define the term virtual as a technology “being on or simulated on a computer or computer network”.

Subject: 500-word summary about the SYVR system.
The following is a 500-word summary of an article about the possibility of SYVR system. The SYVR virtual assembly 5g integrated system has multiple functions, it can construct stable virtual scenarios, capturing multidimensional industrial data, simulate virtual assembly process, and presenting the data visualization result based on its physical simulation which can save time and cost, create more value, improve the quality of product and more efficiency for industrial areas. With the 5G high-speed networks, mainstream VR graphic engines are mainly focused on games, movies, and education areas, the results achieved in industry areas are slightly less and can not meet demand, and are not being diverse enough.
The performance of virtual technology with 5g high-speed networks in virtual manufacture industries are not mature enough and there are many important problems that need to be solved, like the transfer of the real-time data, the generation and visual display under high-speed networks, the build models in a virtual sense, and the implementation of high-level physical simulation techniques, etc.
Based on the article, the system can build virtual environments by using realistic physics simulation and real-time rendering techniques for various industries. We also can adjust data in real-time, present complex scenes, and build the interactive system under the 5g high-speed network environment. And the industrial virtual manufacturing system can import models, process data, and provide visual presentations to users.
The SYVR engine saves a lot of time and cost and brings more value to industrial production and the equipment manufacturing fields by providing virtual test and design simulation because it can construct virtual experiment scene based multi-dimensional industrial data input and processing, also can show user effect in visual and create interactive simulation system but all these functions need to under the 5g high-speed network and the virtual environment.
The SYVR system supported real-time operation guidance, daily inspection, dynamic 3D production display, and employee training which means users can get enough training in the simulation of the realistic industrial production line so as to reduce the number of accidents and improve the quality of products with higher efficiency. The system can provide a high quality of industrial VR/AR while keeping the high bandwidth and low delay based on its strong calculation and real-time simulation, it also can build the industrial digital application system by using its data simulation platform to help 5g high-speed networks make contributions in different areas. Thanks to the development of the 5g high-speed network, it can help the SYVR system make advances on its high-performance industrial real-time simulation graphics rendering engine too so as to have a higher level of simulation effects.
The SYVR project can improve the safety and correct percentage of key operation by using its functions like virtual operation guidelines, daily inspections, and real-time data visualization effects and the need of this system also can speed up the development of 5g virtual technology which expands its application in industrial, medical areas. “Large-scale applications, upgrade the existing VR experience level, provide more possibilities for industrial, medical and other scenarios with high requirements on low latency, and explore more commercial 5G + VR intelligent manufacturing solutions.”[1,p2]
I believe this system can provide people with a work environment with more safety and efficiency.
