Virtual Reality and its prospect
No matter you are a video game player, a movie lover or an industrial designer, you must have learned a lot about the VR 兴奋用英语怎么说(virtual reality). Many media reports 2016 as the first year of VR. At prent, the Steam VR platform has been able to experience the virtual reality game through Vive HTC. Google has invested $0.54 billion in the virtual reality company Magic Leap. It is said that Apple and Facebook also formed a large team compod of virtual reality and augmented reality experts to compete with the other companies in this new, high tech field[2]. Even f英文日期amous director Spielberg declared that he would produce a film about family cooperating with VRC company.
VR (virtual reality) technology can be widely ud in urban planning, interior design, industrial simulation, monuments restoration, road and bridge design, real estate sales, tourism, education, water conrvancy and electric power, geological disasters, education and training and many other fields, to provide feasible solutions[2]. And the video game is the most eagerly awaited女招待 application now. Not long ago, a video game company, Valve, rele
ad a promotional video of its VR: Steam VR. In this footage, players are invited to wear VR equipment and experience all kinds of games, and other people can e their experience in "another world" in a variety of events on the screensubdivision. Everyone no matter player or viewer say it’s really awesome.
So what is VR? How does it work? Virtual reality, multi-media and network technology are known as the three computer technology with best major prospects. This technology is the u of computer simulation to generate a three-dimensional virtual world, to provide urs with visual, auditory, tactile and other simulation, so that urs can be in an immersive unlimited obrvation of things within three dimensional space[3]. When the ur moves the position, the computer carries on the complex computation, maintaining英语四六级成绩查询时间 the spot feeling. In a word, leinaVR technology can bring the ur's perception into the virtual world it creates, and let urs believe that it is true.
景点英语In general, a normal VR equipment consists of one helmet which have a micro procesr and a special optic system to produce parallax and make the 陌生人英文stereoscopic there dimensio
nal pictures, two handles for operating and getting nsation like touching and two speakers to produce the three dimensional sounds. And it also needs to connect to a computer which deals with the information, runs program and help the CPU and special optic system produce scene.
功能英文It’s really obvious that the most important thing for VR equipment is to make the virtuality like reality. The following are veral key technologies to achieve that[4]. First is the real time computer picture simulation. In a virtual simulation system, image refresh is very important. While the image quality requirements are very high, coupled with a very complex virtual environment, the problem becomes quite difficult. Second the images are generated respectively differently in the ur’s two eyes, displayed on different monitors. Parallax will bring a n of three-dimensional then. Third, tracking. When we play computers the mou and keyboard record our track, but the helmet and handles are in charge of it. Last is two important steps of the ur feedback. One is interaction. In the scene of VR, not only the player and player, player and environment but environment and environment all have interaction. It makes the world more real. Another is muti-nsation.
Not only the sound and the sight is three- dimensional ,but you can get touching even smelling by the handles. They both make the scene more real.
However Virtual reality experience refers to still exist many defects now. Some analysts pointed out that the VR technology is not yet mature, experience still exists many blemishes, and equipment costs are too high. It will take time that VR technology comes into public view from “niche toys”. The main problems are significant discomfort, a n of vertigo when wearing, obvious hardware content and so on. For instance, the requirements of the VR equipment image is relatively high. The movie is a cond and 24 frames, but 100 frames a cond of VR device in order to achieve high quality[5]. Thdiaat will greatly increa the computational burden of the hardware, which is difficult to achieve a comprehensive in the industry. Besides the helmet and the handles are a little heavy and the price is still high for ordinary people now.
But there is one word, one flaw cannot obscure the splendor of the jade. Most specialists and forecasters think the prospect of virtual reality is optimistic beyond a doubt. For exam
ple, the GIC (Government of Singapore Investment Corp) forecasts that in 2018, global VR equipment shipments will grow 173% and increa to 0.388 billion from 0.027 in 2015. Another forecaster Enfodesk even predicts that the virtual reality revenues in China will reach to 2160.0 million of Chine yuan although the increment speed in 2017 is slower than before.
Although VR technology is not mature now and still has much room for improvement, we should keep confidence in it. There is a good news that the HTC Vive began to sale a few days ago and more than one hundred thousand people have rerved it even it costs $99
99. According to the Google Trends, VR will enter the era of large outbreak in the near future. So I believe in the not far future, the virtual reality will play the role of the smartphone now and change our life, our social and our planet greatly.
