When it comes to Zuckerberg and his Facebook, perhaps everyone is familiar with it. As a billionaire born in the 1980s, his ability to seize opportunities and see new things helped him create the Internet empire of Facebook. However, when it comes to his acquisition of Oculus with 2 billion dollars, perhaps not everyone knows what Oculus did, Is it worth Zuckerberg throwing billions into this unknown field?

         Oculus is a company that develops virtual reality technology. What is virtual reality technology? In fact, its principle is simple. It replaces the user's original vision through the display image, changes the image through the sensor to recognize the user's head turning, misleads the user's perception, and enables the user to be in the world displayed by the display. In fact, half a century ago, Ivan Sutherland, the father of computer graphics, put forward the virtual reality technology and built the first virtual reality prototype machine with two inch crt displays and some sensors. Although this concept is very advanced, due to the limitation of hardware and the lack of software, the experience is certainly mediocre, and this prototype machine cannot escape the fate of being dusty.

Prototype "Sword of Damocles"

         With the development of semiconductor technology, computer technology has reached its peak, and virtual reality technology has gradually become possible. In 2012, Oculus started the virtual reality development journey by using the crowdfunding platform Kickstarter. In 2013, it launched the developer version of Oculus dk1. Although the resolution of dk1 is only 800p, there is a relatively serious delay problem, and users will see full lattice and screen effect after wearing it, but this cannot hide the incredible experience of virtual reality, plus the "VR Jam" launched by Oculus At the moment, virtual reality applications sprang up like mushrooms in the virtual reality game development contest. Only four months later, more than 20 released games, including "Half Life 2", "Army Fortress 2", "Simulated Surgeon 2013", have provided support, and dozens of games under development have announced their support. More than one hundred demos are available for technical testing.

         At that time, Facebook saw the potential market of virtual reality and had broad application space in entertainment, education, medical care, real estate, military and other fields. In 2014, Facebook announced that it would purchase Oculus VR, an immersive virtual reality technology company, at a total price of about $2 billion. In the same year, it launched the Oculus DK2 developer version, which not only improved the resolution to 1080p, At the same time, by optimizing the efficiency of sensor data collection, Samsung AMOLED is used to reduce the pixel delay, reduce the action delay from 30ms to 19ms, and greatly reduce the vertigo. At this moment, virtual reality begins to commercialize, with a price of 350 dollars, but supply falls short of demand. However, domestic scalpers are helpless, and the price once rose to 6000 yuan (nearly 900+dollars), So few players are lucky enough to experience it.

         At this time, the application of virtual reality has also reached the level of blowout. The castle roller coaster, ultimate terror and other vr games created by the illusory four engines not only make players happy, but also make racing plans With the help of GTA5 and other masterpieces, even adult applications are unwilling to be lonely, and once became the largest potential market of virtual reality. Virtual Real Porn is the pioneer of adult virtual reality panoramic video. It shoots 180 degree panoramic video from the main perspective, so that viewers can be immersive. Now it even adds 360 degree panoramic photography to increase the sense of calm.

         In addition, the playclub and playgirls of ILLUSION, the developer of the famous Japanese working-class game, have joined in the support of the vr helmet, and playgirls has invited the well-known av female actresses Bobo Nokai and Sha Cang to conduct full body 3D scanning modeling.

         It can be said that the prospect of virtual reality technology is very promising. The whole industry has just begun. That said so much, but there is an egg to use. With the existence of domestic scalpers, virtual reality is doomed to have no chance with the Loser Party? People will say that there are more than n xx magic mirrors in China. Speaking of xx magic mirrors, Google used to use the large high-definition LCD screen+gyroscope that came with its smart machine to make a simple virtual reality experience device with a cardboard shell and a magnifying lens. It was really popular for a while, but due to the limitations of the development platform, it was not prepared to spend much effort to develop this product. However, some domestic enterprises took a fancy to this market. Why, With a hundred pieces of plastic shell, you can be immersive. Can imax level audio-visual enjoyment not be attractive? Of course, although this market has quite Chinese characteristics, and although the experience is mediocre and has been criticized, it is undeniable that it can still get a bit of the spirit of virtual reality experience. However, the main venue of the virtual reality helmet is the PC platform, so we will not discuss this distant relative more.

         Since xx Magic Mirror can't interpret the charm of virtual reality, how can many domestic players enjoy the holy grail of this homeboy game party? It depends on our domestic manufacturers. Although many manufacturers are blocked by the technical threshold of virtual reality technology, they can only inject a few plastic shells to fool the white party, but some teams rely on professional knowledge, We have deeply studied the technology of virtual reality helmet, developed our own virtual reality helmet, and there are dozens of companies focusing on this field. Shanghai Lexian is one of the top enterprises in this pyramid.

         In terms of parameters, compared with DK2, Dapeng vr helmet has a lot of parameter improvements. The main aspects of improvement are to improve the refresh rate and reduce the delay, so as to reduce the user's vertigo. The viewing angle is increased from 100 degrees to 120 degrees, increasing the sense of immersion, so it is still worth looking forward to.

PACKAGE

         The Dapeng vr helmet evaluated this time is the version crowdfunded in JD in June. It should be said that it is the first vr helmet product to be mass produced in China, with a crowdfunding amount of more than one million. In addition to some players, there are many virtual reality experience halls and other businesses, and the popularity of virtual reality in the domestic market is beginning to take shape.

         The packaging materials are very generous. Cardboard packaging plus cardboard cover, but the packaging design is not clear whether it should be simple or simple. In addition to logo and deepoon Virtual Reality display, the entire package is spotless white.

         The accompanying accessories are relatively simple, including the operation manual, San Bao after-sales certificate, and the complimentary lens cleaning cloth.

         Uncover the sponge protective layer, and you will get the Dapeng vr helmet.

         At first glance, the workmanship of Dapeng vr helmet is really unspeakable. It is worthy of being a Foxconn OEM. The front cover is made of high gloss plastic parts, and other parts are made of frosted plastic parts. On the left side, there is a cable that links together.

         The right side is equipped with aux3.5 audio output, power key and indicator light. The indicator light switches between red and blue in the non working state and working state.

         The upper side of the lens is equipped with a heat sink, which is pasted with a metal mesh to prevent the lens from fogging and prevent dust and foreign matter from falling. In actual experience, the heat sink will not cause light leakage.

         The top and left and right sides of the Dapeng vr helmet are equipped with buckles to install the headgear.

         The bottom is pasted with Dapeng's specification parameters, 3c certification and bar code. It is worth mentioning that Dapeng's nose design is based on the pen shape design of Asians, and it will not cause serious light leakage when Asians use the dk2 because it adopts the nose shape design of Europeans and Americans.

         A circle of black sponge is set near the face of the Dapeng vr helmet, which has good fit and elasticity, and is very comfortable to use without light leakage.

         Dapeng vr helmet uses two aspherical lenses with a diameter of 40mm, adaptive pupillary distance of 54mm-74mm, and can optically correct myopia. However, I am not very fond of myopia correction, because high myopia is usually accompanied by astigmatism, so I still need to wear glasses. The space in front of Dapeng lenses is very ample, and I have no trouble wearing large frame glasses.

         The transmission cable of Dapeng vr helmet is protected by braided network pipe, which increases the strength of the cable. The total length has been assessed to be 250cm, which can fully meet the activity radius of different body feeling accessories.

         The cable is composed of USB and HDMI. The USB power supply transmits the gyroscope data, and HDMI transmits the video signal.

         The fixed end of the head cover adopts the elastic fabric structure between two sticky straps at both ends. The elastic fabric can be placed and worn too loosely.

         The weight of the Dapeng vr helmet is about 540g, slightly heavier than the 440g of the dk2, but the 100g will not burden players.

         Girls will not feel heavy and uncomfortable if they wear it. They especially tried it with a beautiful woman. The head cover of Dapeng's vr helmet is fixed firmly, but not too tight.

         After talking about the hardware part of Dapeng vr helmet, let's talk about Dapeng Help. Because Dapeng vr helmet not only has its own development platform, but also is compatible with DK1 DK2, so as to experience the software developed on the DK1 DK2 platform, Dapeng Assistant is a software end tailored for Dapeng vr helmet, which can switch three modes of DK1 DK2 Deepoon with Dapeng helmet, It also provides a convenient game download section, and will add a panoramic/panoramic video download section in the future to facilitate users.

         Dapeng Assistant also needs the user to enter basic information. In addition to myopia and pupillary distance adjustment, it also needs to enter gender and height to match the main view attribute of the software personalization in the future.

Game experience:

         This is a virtual reality experience developed by a UE4 engine. The whole process is passive, but the perspective can be active. It takes you to experience a fantasy journey. The whole process involves traversing and panorama. The production tidbits of internal characters are live actors. Unlike panoramic videos, most of the scene content is 3D modeling, and of course, there are full of special effects and bizarre plots, The sense of immersion is first-rate, as if incarnating as the protagonist to experience four incredible environmental experiences. When Big Friend vr experiences, the perspective conversion is very smooth, and no frame can be seen in the perspective, so there is no vertigo.

         DK1 The most familiar experience demo is the castle roller coaster. This is a remake of the UE4 engine. The whole experience process is still the same thrilling. The scenery under the castle is spectacular. When diving down, it immediately feels out of balance. Unfortunately, the vision and hearing can be misled, but the sense of body is not misled, so you still have to go to the experience store to experience the 4d version. During the experience process, There is also no sense of vertigo, and the sense of immersion is first-rate.

         As the first conscience company in the minds of otaku men, these two masterpieces brought by illustration may be the reason why a large part of otaku men pay for vr helmets. Of course, the experience process is also full of benefits, Playclub may have some inconvenience in blind operation with a helmet, while Playgirls directly adopts the head aiming operation mode, which is full of sincerity, so it is inconvenient to say more about the effect. Anyway, players who like the mouth game, you will have played the mouth game for so many years without a vr helmet. I can only say that if you wear a big friend vr helmet, you will be a big director of av.

         The racing plan has to be explained in more words. First of all, Dapeng assistant does not support extended screen mode, so we have to use oculus runtime setting software to play racing plans through Dapeng helmet. Racing plans are the most immersive in so many games, not because of the beautiful pictures, because after 1080p is divided into two screens, No matter how high the resolution is, it will not improve the perception, but because of the weather elements in the traffic jam plan, such as rain hitting the glass, and the sun shining into the car, which is a real experience of simulating the driving environment. Because my mainframe is not high, in fact, the fluency is the worst among many experiences, but it is the most touching.

Movie experience:

         As Cameron's masterpiece that ushered in a new era of 3D, no 3D production has surpassed him so far. It's all 2009 movies. It seems that only when Cameron has transcended himself, as each eye has its own corresponding independent picture, the effect of watching 3D movies by friends vr must be unspeakable, and there will be no duplication, Some people may doubt whether the resolution of 1080p movies is not enough. After all, the principle of vr is to divide a whole screen into two pictures on the left and right. But when actually watching, the whole picture is about 3 meters away from 200 inches, so if you are immersed in the movie, you will not care about the resolution.

         What's more, as virtual reality glasses, it is unimaginable that through professional virtual reality cinema software, the scene of the cinema will be simulated, and seat selection is supported. You can watch movies from different perspectives. With contrast objects, you can feel the feeling of imax theater more, rather than just filling in the picture about how many meters and inches.

Panoramic video experience:

         This ghost movie is called 11:57, which is very mysterious when I hear it. It uses 360 degree look around shooting technique. I watched the whole movie with my hands on the helmet, and did not use a headcover to fix it. I'm afraid I won't be able to escape in time. It's too embarrassing... The whole story is the main character, that is, I am tied to a chair in a basement or an air raid shelter. I can't move, I can only rotate the perspective, watching the lights flash and flash, and ghosts come out to frighten me. Anyone who has seen those scary videos should know that the ordinary picture suddenly runs out of a grimace and yells. This is an advanced version, not a display, But live in front of you.... Anyway, after seeing all white hair sweat.

         You must be looking forward to the experience of watching these two immoral x-films. Anyway, the process cannot be described in detail. The 180 degree immersion is far less than the 360 degree immersion, because the 180 degree random viewing angle can see the boundary when you turn a larger point. And when you look at such films, you finally feel that the resolution of Dapeng vr is a little insufficient. Why? Because the film is about macro and atmosphere, and the x film is about micro and details, I think at least 4k is enough.

         Because of the time problem, only some representative software and resources were selected in the whole experience process. The whole process is still very incredible. Compared with the traditional display, Dapeng VR helmet brings more immersion and presence. Of course, this requires the support of software. At this stage, although it is not easy to get, it can be seen everywhere, Unfortunately, there are few big productions, but I believe they will be launched in 2016, but by then the players' consoles will have to be upgraded.

         In addition, everyone should pay more attention to the vertigo and resolution of Dapeng vr helmet. To be honest, the vertigo is perfect for me, which shows that the motion delay and picture delay of Dapeng vr helmet are very good, which can not be tested by software, but can only be expressed by personal feelings. When the resolution person feels playing games, 1080p is enough, because up to the 2K level, I have to change the host, and the pixel response of the LCD is slow, so the LCD panel of the oled must be used to achieve a refresh rate of more than 75hz, The Morpheus not released by sony still uses 1080p resolution, but its unique oled technology can achieve an amazing 120hz refresh rate. Therefore, the first element of virtual reality helmet experience is to reduce action delay and picture delay, It seems that the virtual reality helmet of 2K oled is only the oculus right cv1 released in 2016 at this stage, but the domestic Hehui Radio and TV has lit up the 4k 6-inch amoled screen. It is believed that the high-definition vr is getting closer to us, and Dapeng has also started to develop the 2K version of Dapeng helmet.

         In the experience process, Dapeng virtual reality helmet is not perfect. Because of the driver, some dk2 games need the control end software of oculus runtime to open the screen expansion mode to run, while a small number of dk1 demos cannot support it. Maybe more games I have not tried have other compatibility problems, but as a product compatible with other people's hardware standards, It is commendable to be able to achieve this level. I hope that the driver and Dapeng assistant can be optimized in the future to have a higher compatibility. At the same time, I look forward to the software developed on Dapeng's own sdk. I heard that Dapeng has jointly launched VR games grandly, and I hope to see the style at the first time.

         Finally, I would like to thank Shanghai Lexian. Compared with Oculus right dk2, the sales price of Dapeng helmet is nearly 1800 yuan, and the cost performance ratio is not one or two points. In addition, the manufacturing process of Foxconn is far better than DK2, which should be said to be the most competitive virtual reality helmet in China at present. I hope Lexian will continue to make efforts to create more benefits for the domestic vr industry.
