Vr glasses and glasses helmet.

VR is not as optimistic as we thought.

_ VR has been on fire for a long time and has become the darling of the technology circle. Nowadays, the popularity of VR is just like O2O. Now I don't need to say more about the decline of O2O. Is the prosperity of VR just a flash in the pan?

_ First of all, I'm not optimistic about VR, although the major media overwhelmingly praise the prospect of VR, claiming that the overall revenue of the global VR/AR industry will reach $85 billion after 10. Although I don't know the reliability of this data, at least in my opinion, VR will not be as popular as people think.

_VR devices can really give people a sense of freshness. I also bought a pair of VR glasses out of curiosity. On the first day, I played some games with glasses. I saw some short films and put them there.

_ After a simple experience, let me talk about the limitations of VR development.

_ First of all, VR helmets or glasses should not be worn for a long time.

_ Anyone who has played with VR glasses will notice that VR glasses are not suitable for wearing for a long time. I felt a little uncomfortable and even a little dizzy because I wore glasses for a while. Future games are the most important field of VR hardware applications. But everyone who plays games knows that it usually takes more than an hour to play a game. But for now, VR glasses are not suitable for normal online games, only for impromptu games, and the playing time must be short.

_ Second, VR usage scenarios are limited.

_VR glasses must be used in a safe space. After the VR glasses are brought up, people's vision is limited to the video and they cannot observe the outside world. This situation limits the use of VR glasses or helmets in a relatively safe space. This also hinders the popularity of VR glasses.

_ Third, the interaction is weak

_VR devices are actually isolated from the surrounding world after being put on. What the other party is doing and playing, in fact, onlookers can't feel the same. It is almost impossible to interact with people around you. This limitation leads to the fact that VR can only be a carnival for one person.

_ Fourth, VR cannot be combined with mobile phones for a long time.

_ There are several situations when watching VR videos on mobile phones.

_ 1: The mobile phone consumes fast power.

_ 2: VR video takes up space

_3: Will be disturbed by incoming calls or text messages.

_ Maybe fast power consumption is not a serious problem, because after all, the wearing requirements of VR devices are usually indoors. So everyone has a power supply, but the second one, VR video takes up a lot of memory, but it is a big problem. At present, the source time of VR video on the market is very short, usually within 5 minutes. Still in the experience stage. Assuming that there are enough VR videos in the later period, people will find that the memory of a general mobile phone cannot carry VR videos. The third question, suppose that VR videos will be watched through mobile phones in the future, but there will always be messages and incoming calls during the video playback. A person who wears glasses or a helmet. It's inconvenient to take off the mobile phone in your glasses and answer the phone.

Of course, I think most of the fourth point mentioned above can be solved by technology, such as the interference of incoming calls, not wearing glasses and helmets, and playing games while answering the phone directly, all of which can be realized by technology. It's just a matter of time. However, the user's dazzling situation and the limitations of usage scenarios will greatly hinder the popularity of VR.

_VR is the future trend, there is no doubt about it, but VR will not be as popular as people think, and it may be more used in some professional fields. In addition to adults, games and movies that can be imagined now, the actual VR can also be applied in the education industry, advertising industry, children's toys, shopping and so on. The VR industry is now in full swing, and all the giants are involved. I don't know what essence will be left after a fight. But in any case, the road of VR is still very long, and it is just the beginning.

What's the difference between VR helmet and VR glasses?

Hardware and price difference: VR glasses mainly rely on lenses as the technical core. With the help of mobile phones, users can create a visual experience with their eyes in a black closed space. The hardware of VR helmet constitutes a VR helmet, which is an independent tool without mobile phone peripherals, and has many components, sensors, Bluetooth, wireless signals and other hardware. Of course, because the former has a simple hardware structure (generally only one shell, headband and two convex lenses), the price of VR helmet (generally 1000 yuan or more) is generally much higher than that of VR glasses (generally 10 yuan or less).

Different visual range: As far as VR glasses are concerned, the size of the picture when VR glasses watch video depends on the size of the mobile phone. In addition, the visual effect of feedback is that there are black edges up and down, which greatly reduces the experience. Compared with VR helmet, wearing a helmet has no dead angle in the visual range of eyes. According to helmet products produced by different manufacturers, the visual field width is between 86- 120.

Clarity: There is no special comparability in clarity. At present, the maximum resolution of the mobile phone is 1920* 1080, while the resolution of the top-level helmets known at present has reached the level of monocular 1200* 1080. So if you count the average eyes, it seems quite high. However, from the actual effect, the helmet has obvious graininess, while the mobile phone does not.

Vertigo: Because the quality of gyroscope directly affects the vertigo effect of users watching movies, if you use a gyroscope with poor quality, you will feel vomiting. This personal experience is that VR helmets are better. The difference between ar glasses and vr glasses

The difference between ar glasses and vr glasses, many users have searched what ar and vr are, but you can look at Baidu Encyclopedia, which is the official industry vocabulary. For some small white users, I simply can't understand the difference between AR glasses and VR glasses.

The difference between ar glasses and vr glasses 1

The biggest difference between VR and AR is that the scenes and elements seen through VR are fake and all made by computers. The scenes and characters seen by AR are partly true and partly false. AR brings real objects and virtual ones into the real world through the camera (key point), which is more real.

Take W2 smart glasses (AR) and virtual reality helmet (VR) as examples:

Difference 1: W2 smart glasses are designed in strict accordance with ergonomics, with traditional glasses design technology, multi-point stress, dual-screen display, small size, foldable and easy to carry around; Virtual reality helmet is equivalent to mobile phone+lens, which is designed with binding force, so it is relatively large and heavy. The other is a single-screen monitor, which is uncomfortable to wear and will make you dizzy after watching it for a long time.

Difference 2: Platform function W2 smart glasses have AR function and provide an all-round AR open platform, which brings users a new shocking experience of real-time integration of AR dreamland and reality. Glasses can not only watch and listen to songs online, but also check the weather, take photos and interact with mobile phones. There are many functions, all of which are realized through glasses; Virtual reality helmet (VR) is limited to watching videos in 3D split-screen format, and needs to be downloaded in advance by mobile phone. It has a single function and is simply a video player.

Difference 3: Video playback mode W2 Smart glasses are different from most smart glasses on the market. W2 smart glasses don't need to be downloaded. You can watch movies online as long as you link to WIFI. Of course, without WIFI, you can also cache it first. Compared with the virtual reality helmet, it is much worse. Not only can it not be cached, but it can't be viewed online. It needs to download the movie to the mobile phone and plug it into the virtual reality helmet to watch it. Simply put, the virtual reality helmet is actually equivalent to a video player.

Difference 4: Supported movie format W2 smart glasses adopt chips imported from the United States, with a physical resolution of 854*480. It supports left and right 3D movies and all 2D movies, and also supports 1080P HD playback and high-fidelity images, presenting clear and bright pictures with bright colors. Virtual reality helmet is equivalent to mobile phone+lens, and you need to use 3D split-screen format resources downloaded from mobile phone to watch movies.

Difference 5: adopt different technologies. W2 Smart Glasses (AR) is an all-in-one machine, which is the crystallization of the latest photoelectric technology. Virtual reality (AR) helmet is a combination of mobile phone and lens.

Difference 6: In terms of content, W2 Smart Glasses (AR) cooperates with China Digital, and the contents of glasses are all provided by China Digital, with rich and diverse contents; The content of the virtual reality (AR) helmet depends entirely on the content downloaded from your mobile phone.

Difference 7: W2 smart glasses are equipped with goggles when they leave the factory, which can not only be used as a hood, but also be equipped with myopia lenses, which is more convenient to use and can be directly used for mild myopia; The virtual reality (AR) helmet rarely considers the user's vision.

The second difference between ar glasses and vr glasses

To say that this year's hot words VR and ar are definitely indispensable, it is said that this year is the first year of VR, but there are not many users who really understand VR. Speaking of ar technology, Pokemongo (Poké mon go), which was popular all over the world a while ago, once again pushed AR technology to the craze. For some people in unknown so, AR and VR are even more silly.

Many users have searched for what AR and VR are, but you can look at Baidu Encyclopedia, which is the official industry discourse. For some small white users, it is impossible to understand this tall expression. Here I will tell you what AR and VR are, and what's the difference.

VR（Virtual Reality）

Immerse yourself in the virtual world to consume content, giving users an immersive feeling. It is to create a virtual reality world. Users use VR devices to bring themselves into this virtual world. Whether in games or movies, users can use VR devices to fully integrate themselves with the virtual world and experience the immersive feeling.

AR（Augmented Reality）

AR is augmented reality, also known as mixed reality. Through some computer technologies, virtual information is applied to our real world, and virtual commodity information is superimposed with our real world, so that they appear in the same picture or space. Just like Pokemon GO, we can scan a scene and run out of elves. In the future, this technology will be mature and widely used. For example, when a user scans an object, the description and application of the object will come out.

The difference between VR and AR

VR is a virtual scene, and users need to connect VR devices to enter the virtual world (games, movies, etc. ), and users need VR devices to interact with the virtual world.

AR is a combination of real world and virtual information, so basically it needs a camera, and virtual information is added to the scene shot by the camera for display and interaction. At present, there are many AR softwares, and you can search some AR softwares to experience them.

The difference between ar glasses and vr glasses 3

Since 20 16, VR technology and AR technology have been the focus of attention in the industry, and the .5g commercial license issued at the end of last month has once again pushed VR to the forefront of AR. But even if the discussion has not stopped, many people are still in a state of incomprehension about VR technology and AR technology. So, what is the relationship between VR and AR? What are the similarities and differences between them? In order to answer your question, Arji bought this article, hoping to really "answer questions".

What is VR/AR? VR, VR (Virtual Reality) and AR (Augmented Reality) are the latest technologies that have attracted wide attention in recent years. Although both have virtual components, their proportions are different. For people who are not familiar with this field, it is easy to confuse the two. In short, the difference between VR and AR is that the former is completely virtual and a brand-new scene, while the latter is superimposed on the real scene, and the feeling is more real and natural. In addition, the difference between AR and VR lies in the interaction mode, application mode and development direction.

VR（Virtual Reality）

VR virtual reality scene is interactive, not one-way. This is the same as we interact with smart phones by controlling their screens. Here we interact with computer machines through mouse and keyboard, and the mainstream control interaction modes of VR devices are as follows:

Gesture control: users can interact in the VR interactive scene they see by wearing specific glove devices.

Head tracking: it means that the scene in VR line of sight will change according to the head's visual angle movement.

Tactile feedback: this is more powerful, that is, users wear specific VR protective gear, which will help users achieve tactile feedback in VR scenes. For example, when playing a gunfight game, the protective gear will simulate the feeling of being hit.

The visual effect of VR scene is 3D, but it is essentially different from common 3D games and movies. The range of human eyes under a fixed visual angle is usually about 120 degrees, which is also the best range for us to watch movies in the cinema. If it exceeds this range, the line of sight will overflow the screen, and the 3D effect brought by the screen will be lost. Compared with the traditional 3D screen, the difference is that VR has a 720-degree 3D immersion, that is, no matter how you look at the internal scene of VR from all angles, it will produce a 3D effect, so that you can observe all the pictures. This is the so-called "immersion" of virtual scenes.

AR augmented reality

Different from the immersion of VR virtual reality, AR augmented reality is to enhance the visual experience of the real world through devices. In other words, the feeling does happen in the real world where the experiencer lives, but the virtual scene is superimposed on the real world by using equipment, which brings more levels of feeling.

Relative to the full set of VR equipment (helmet, gloves, etc.). ), AR devices are often lighter, such as Google Glass products.

In addition to wearing, AR technology is mostly realized through smart phone applications, and at present, many Internet technology companies have joined the ranks of AR applications based on app. For example, AR Ji Bu APP is an application-oriented app with AR technology as its core. It overlays a virtual scene (3D model of a product) on the real world, allowing users to experience the application effect of the product with their own eyes in the real environment and realize early perception of the product effect.

In addition, by purchasing the scanned product object through AR Ji, a series of parameters of the product can be immediately called up for users' reference. Compared with enterprise sales, this will be a brand-new application and a tool carrier to completely improve enterprise sales. At present, AR Ji Bu has been opened to furniture, machinery, packaging, ceramics and other manufacturing enterprises, making the sales experience of enterprise products more interactive.

Development direction of augmented reality/virtual reality

It can be seen that AR and VR are still very different, so in terms of development space, the combination of the two can completely change the entertainment and life experience of human beings, which is beyond doubt, but in terms of direction, what is the difference between the two?

Let's discuss VR first. Because of its completely virtual scene, it may focus more on entertainment and experience in applications, such as games and movies. Headphones will open the 720-degree experience mode, allowing you to completely enter the virtual environment, breaking the current limit of viewing angle 120 degrees through the screen, bringing better interaction and a broader viewing experience.

Unlike VR fully virtual scenes, AR technology combines real and virtual scenes, in other words, you can see both real and virtual environments at the same time. For example, in the street, you can scan the promotion activities of the supermarket through the mobile phone camera without entering the store, and you can see the graffiti left by the people sitting on the street bench in this virtual space before, and so on. All this can only be achieved by combining virtual and realistic AR technology.

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

Full name is virtual reality glasses.

It can be used to watch videos. The specific usage is in the product description. Just connect a player.

For example, wearing these glasses to watch a movie feels like sitting in a big cinema and watching a movie alone.

Namely VR head-mounted display and virtual reality head-mounted display device. 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. 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.

AR(AugmentedReality) is augmented reality, also known as mixed reality. It applies virtual information to the real world through computer technology, and superimposes the real environment and virtual objects on the same picture or space in real time.

VR(VirtualReality) is virtual reality, or VR for short. Its concrete connotation is a technology that comprehensively utilizes computer graphics system and various interface devices such as reality and control to provide immersion in a computer-generated interactive three-dimensional environment.
