What are the features of VR
Refers to in addition to the general computer has visual perception, and auditory perception, touch perception, motion perception, and even including taste, smell, perception and so on. The ideal virtual reality should have all the perceptual functions that people have.
The degree to which the user feels as the protagonist in the simulated environment. The ideal simulation environment should be such that it is difficult for the user to tell the difference between real and fake.
It refers to the user's manipulable degree of objects in the simulated environment and the natural degree of feedback from the environment.
The degree to which objects in a virtual environment behave according to the laws of physical motion in the real world.

Five existing barriers to VR
1. There is no real way to enter the virtual world
A well-known joke in Oculus Rift development circles is that whenever someone asks users to stand up and walk, they are usually afraid to do so because the Rift still has to be wired to a computing device, which greatly limits the user's range of movement.
Vr gear, including the Oculus Rift, continues to block communication between users and the virtual world. These devices cover our eyes and change our line of sight, but they don't cover all of our field of vision. The awkward use of a mouse and keyboard was already awkward, and any attempt to move a large area was bound by cables.
"We don't want users to get hurt." Oculus VR founder Palmer Luckey.
Some developers have considered creating a room for virtual reality equipment, but the problem isn't likely to be solved so easily. Truly immersive experiences in games include squatting, dodging, and even climbing, which currently do not provide a realistic immersive experience for users.
While there are third-party solutions such as the Virtuix Omni treadmill that allow players to safely simulate movement within a fixed space, these large machines are often expensive and not affordable for the average gamer.
2, how to "input" is also a big problem
Perhaps the bigger challenge of virtual reality is how to interact with objects in the virtual world. The Oculus Rift tracks the user's head, but not the rest of the body. The player's hand movements, for example, are now impossible to simulate. "Input is the most important and obvious experience for the user, and if you can't simulate the action, the user will always lose track of where their hands are." Luckey said.
Virtual reality inputs are a big concern for game developers and hardware manufacturers. Although the Xbox controller can now be used as a PC controller, there is still a lack of experience in practical applications. Other controls, such as the Razer Hydra and STEM systems, promise a lot, but still don't mimic the user's hands.
At present, there is no clear way to know how to realize virtual reality technology in gesture tracking. "We all know that something is not right, that it has interfered with our communication with the virtual world." Luckey said. Oculus still seems to be working on its own input device, but it hasn't done much yet.
"Some people are taking steps, but no one knows what they are going to do right now. There are controllers, there are guns, but what we need is a dedicated input device for vr devices that will become mainstream. It doesn't have to be perfect, but it has to be better than a sword, a gun or even a pair of hands. It's very difficult, but simulating a hand is harder than a gun." He said.
3. Lack of uniform standards
Vr is still in its infancy, and there's no doubt that everyone has their own way of demonstrating the platform, whether it's rough or slick, but it's all about the last few minutes. While many developers are enthusiastic about virtual reality, there seems to be no unified standard.
As a brand new platform, it will only succeed if it generates interest, including actual experiences. DVD movies, game consoles and even YouTube have become ubiquitous just because so many people are interested in them. Similarly, if VR is to stand out, it must appeal to more than just professional enthusiasts. This is especially important for older or non-tech enthusiasts.
"Some technologies seem cool at first, but gradually become less attractive. Clearly, it will take years for vr platforms to grow into a giant tree." Luckey said.
The experience may not require much technical expertise, just a realistic virtual reality experience. Luckey points out that people usually like things that most people like, and that sharing is more fun.
The Oculus Rift has two apps for Samsung's Gear VR, one for watching movies and the other for viewing 360-degree photos.
"The utility of these tools is very important because many people will use them over and over again." Nate Mitchell, vice president of VR products at Oculus. "It's like smart phones today. It's not the best one for listening to music, but at least you can listen whenever you want. It's convenient. I've tried to watch a movie with a vr device and it's really great."
4, easy to make people feel tired
Any game developer or movie production company should know how to use a camera differently in a virtual reality setting. The experience of moving and sitting is very different. The accelerated motion of the camera creates a different focus, which, if not used properly, can make the user feel sick. Even if the lens moves too fast, it can temporarily affect the user's vision.
Some people are more sensitive and prone to vertigo. While Oculus VR CEO Brendan Iribe says the latest product is designed to avoid discomfort for users, it still requires hands-on experience. Other studies have shown that women are generally more uncomfortable with these devices than men (and fewer women are involved in testing virtual reality devices).
5. It still looks stupid
This last point may seem superficial, but it is equally important. It was a professional gaming device, but now it feels clunky and unnatural, and even looks silly. While we don't know what the final Oculus Rift will look like, making it light seems unlikely at this point.
While The Oculus Rift isn't meant to be used in public places, it's definitely not acceptable to the average user. But the problems aren't insurmountable, and most developers familiar with vr gear say it won't be difficult to make devices look better in the future.
While virtual reality may seem rudimentary right now, it could one day be one of the biggest transformations in the way we interact with computers, changing our relationship with technology. Virtual reality will eventually allow us to interact more naturally with the virtual world.
How to find VR resources
First, mobile app store, query VR special software, download resources to watch.
Each mobile phone will have its application market for us to download software, we can find some special software, and then go to download the resources we want to watch, the mobile phone can play. However, although this method is the most common and simple, but can see the resources is not much, often we want to see some resources can not find, this can do? You know...
Second, Baidu Post bar and related forums, search for resources.
If you want to find resources, how can you get less posts? Baidu post bar crouching Tiger hidden dragon, is a real master gathering place, is the so-called help for happiness, home travel necessary good character ah! So as long as we speak for help, there will be more or less some leaders to help us, as long as the leaders give a little help, we are afraid that there are no resources to see? Of course, in some forums, we can use this method as well.
Third, go to foreign websites to see.
Compared to the first two methods, we can basically get most of the resources we need, but if you want more excitement! That might as well go looking on a few websites abroad. Although say the resource of home also and not little, but relative to abroad, can be some small not see big not really, that much is simply more than cow hair even, all sorts of types are all ready, want you to think of only, basically can get satisfied.
