Virtual travel of vr glasses

What are vr glasses? What's the use? How to use it?

1. What are VR glasses?

VR glasses are VR head-mounted displays and virtual reality head-mounted display devices. Because there was no concept of head-up display in the early days, unprofessional names such as VR glasses, VR goggles and VR helmet were produced according to their appearance.

Second, what is the use of VR glasses?

VR head display is to use head-mounted display equipment to close people's vision and hearing to the outside world and guide users to feel in a virtual environment. Its display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eye will have a stereoscopic impression in its mind after obtaining these different information.

VR glasses are products that combine simulation technology, computer graphics, man-machine interface technology, multimedia technology, sensor technology, network technology and so on. It is a brand-new means of human-computer interaction created with the help of computers and the latest sensor technology, which not only surprises every amateur, but also fascinated by its birth and prospect.

Third, the use of VR eyes:

Many cheaper VR glasses on the market need the help of mobile phones. Put a 4.7-5.7-inch mobile phone into VR glasses, download the corresponding APP in the mobile phone (according to different brands, you have your own mobile phone software) and you can use it.

There are all kinds of VR software in all major application malls of mobile phones. I use "orange VR" and many other softwares. I won't list them here, but the method of combining mobile phones with VR glasses is similar. Details are as follows:

1. Find the switch and turn on the VR glasses (different brands of VR glasses have different power-on keys, please refer to the instruction manual of VR glasses for details).

2. It usually takes two necessary steps to download VR software with a mobile phone.

The first is to pair VR software with VR glasses.

The second is to set the screen size of the mobile phone to make the screen size conform to VR glasses.

3. After the VR software of the mobile phone is set, the screen of the mobile phone will split left and right after clicking the game or 3D environment you need to experience.

4. Insert the phone into VR glasses. Different cups are placed in different ways. After putting it in, you need to align the center line of the left and right split-screen videos with the center line of the glasses.

Brief introduction to the principle of VR glasses

The principle of VR glasses is similar to our eyes. Two lenses are equivalent to eyes, but far less "smart" than human eyes. In addition, VR glasses generally divide the content into two screens, cut them in half, and achieve superimposed imaging through lenses. At this time, the center of the pupil, the center of the lens and the center of the screen (after split screen) are often not in a straight line, which makes the visual effect very poor and leads to many problems such as unclear and deformation. [3]

In an ideal state, the eye pupil center, lens center and screen center (after split screen) should be in a straight line (as shown in the following figure). At this time, it is necessary to adjust the "pupillary distance" of the lens to coincide with the pupillary distance of the human eye, and then adjust the center of the picture with software to ensure 3 points 1 line, so as to obtain the best visual effect. Some domestic devices are adjusted by physics or software, such as Storm Mirror, whose pupil distance needs to be adjusted by the knob above, and SVRGlass needs software to adjust the pupil distance.

What are the tourist attractions of vr?

VR tourist attractions are to experience real-life simulation and 3d effects. Put on VR glasses. Thank you, please adopt!

"Virtual University Tour" is a good tool to weigh the choice of institutions or "visit" the campus in advance. The "Virtual University Tour" has many benefits. I have carefully prepared some information below. Let's have a look!

From picturesque waterfalls on forest paths to lively Weaver ball games, virtual university tourism provides a part of campus life.

Foreign universities are using 360-degree video and virtual reality technology to welcome potential students from hundreds or even thousands of miles away. Virtual tourism can be used as an early classification tool for students to measure universities, and it can also help those students who can't visit to see the schools. In any case, virtual travel is a useful way for students to get familiar with the campus.

Joe Lackner, director of network communication at Hanover College in Indiana, said: "I think this is a real way to watch the campus, and you can really feel the real feelings on campus."

Students who want to study in Hanover College can click on interactive photos and videos through a virtual tour on the Internet, which is set to be compatible with all devices. Another option is to download the Hanover Experience app and enter virtual reality, but you need to wear VR glasses. The virtual tour of Hanover hopes to give students a general understanding of university life, whether from school buildings or school activities.

Lechner of Hanover College explained: "We have a beautiful campus, which is part of our brand." Hanover is not the only university that relies on virtual tourism to attract potential students. The University of North Carolina system provides 16 campus landscape for students who want to study abroad through online virtual travel and virtual reality application experience. A spokesman for the University of North Carolina explained that the purpose of including these campuses in virtual reality is to increase the educational opportunities of students, especially low-income families or first-generation students, because they may not really visit the campus.

Jason Tai Sen, director of the Media Relations Department of the University of North Carolina, said: "If (future students) cannot enter the campus in person for various reasons-time, travel, expenses, etc.". -This (virtual tour) allows them to experience campus life. "

Because of virtual travel, students who browse the University of North Carolina system can quickly reach Elizabeth City State University from the University of West Carolina in a few minutes, which saves seven hours' drive between the two campuses, saves money and allows families to plan other visits. For students who live out of state, virtual travel can help them learn about the campus from a distance. So do international students.

"International students are unlikely to visit the school on the first day of school," Lackner said. "The more campuses we can show them, the better."

The well-made virtual university tour also provides the charm of the school, and experts say that students should not see this charm in other marketing materials.

Stephanie Huff, assistant vice president of marketing and recruitment at the University of South Florida, said, "Students are watching the most complicated marketing promotion in the world. They won't like old postcards and leaflets. The University of South Florida has a variety of virtual tourism options, including 360 panoramic view and VR landscape services.

According to a report of 20 18 of the National College Admissions Advisory Association, more and more prospective students apply for more schools. According to the statistics of American College Admissions Advisory Association, more than 80% freshmen applied to at least three universities. As the waiting list is longer than ever, students can use virtual travel to weigh the choice of institutions.

Hundreds of schools now offer virtual travel services, from campus photos clicked by users to detailed options in student guides. These services show various school facilities and introduce other potential applicants to students.

Lackner urged future students to do their homework before arriving on campus: "Choosing a university is not a small decision. This is a life-changing decision, so the more you can understand your situation, the better. "

The school staff suggested that future students should take virtual travel as the starting point, and then weigh the factors that affect students' experience in school, such as academic courses and admission requirements.

Although school staff praised virtual tourism as a good choice, they encouraged students to visit the campus as much as possible. Tai Sen said: "It (virtual experience) can never completely replace the real university visit experience, and we have not tried to do so." Tai Sen added that for many students, virtual travel is a starting point, which can help them make initial decisions.

Huff pointed out that in general, students should know five things before applying for a university: admission requirements, application process, admission fees, majors offered by the school and campus life. For her, the key role of the virtual university trip is to understand campus life. Other problems are best left to the admissions office. One of Huff's colleagues suggested that students learn about the campus from virtual trips and then ask other questions to the school.

Jared Brown, creative director of video production at the University of South Florida, suggested, "If you want to take a virtual trip, dig deep and move on. Virtual travel has almost endless content. If you have any questions, just ask, and the school will provide you with the phone number. "

What equipment does VR virtual reality travel need?

If you travel in Vr virtual reality, you need a high-profile computer first. In addition, you need virtual reality glasses. If you want to improve your immersion, you can add some somatosensory devices such as somatosensory vests.
