Appearance and workmanship

https://www.youtube.com/watch?v=rCMc5Y73OTg Transfer box is very simple, a boxy white big box Center reads "turn for the home" and the cartoon portrait of a family of five, on the right is the Logo of loving eyes and ears.

Sides printed with a small turn in the box product, and Baidu is clouds support.

Box with magnetic design, remove the cover we can see small round. Small turn by thick sponge fixed inside the box, do not worry about damage during transport. Side tray for data cables, chargers, and other accessories.

Here are short turns and all accessories.

Power supply 5V 2 a.

Instructions come with a stuck needle, so that we can use when resetting the machine.

Xiao Zhuan style simple, composed of a white fuselage and wood grain rotating base composition. Simple shapes from domestic famous design company Rococo, by the well-known Café – Rococo intelligent hardware head Li Fancong built.

Back to hollow out openings and Micro USB interface. Perhaps it is because we are in the hands of engineering machine, had obvious traces of glue at the seams at the back, hope on the production version could be improved.

In addition to horizontal, but transfer also supports vertical 120-degree angle. Don't look down on the shaft, short turns in order to ensure the appearance of the machine and six drafts, has been carefully considered every angle, through a series of elaborately carved, and finally determine the final version of each ARC is perfect.

The camera (the nose) can be removed, after removing the camera body interior is slightly larger, loving eyes and ears seem to be the fuselage can be made more compact.

This eye is the essence of short turns, there is 720P and 1080P two kinds of specifications. In accordance with loving eyes and ears the official version, the head can be replaced, love the eyes and ears of the present and future head of universal. Our hands-on experience of this one for the 720P version.

Operation and use

Small turned main family level security monitoring, has high clear, and infrared night depending on, Super big rotating perspective, features, and many similar products different of is small turned using has Baidu cloud to store monitoring video, factory attached gift has one months of "7 days Baidu cloud service", that in one months of service cycle within, Baidu cloud will automatically store recently one week of video.

After connecting the power supply, camera LEDs flashing alternate red and blue at the bottom, 15 infrared light emitting LED lights will light up, also move around a total of 360 rotation.

After loving eyes and ears App is installed need login Baidu is clouds account can then paired with short turns, plug in the WiFi can be used.

Experience

As a webcam, video quality of experience is the ultimate standard for measuring it. Transfer video slightly different from the other webcam, it first through the WiFi to send real-time video to Baidu, and Baidu is clouds encrypted to our cell phones and computers that we see "live pictures" is already stored in the Baidu on the cloud "live video".

Transfer Super clear, high definition and clarity smooth three to choose from, with Super clear picture, for example, real-time screen flow, picture clarity is good. But that may be because after Baidu is clouds transit account sent to the phone, the screen slightly some delay, rotations also have a certain degree of retardation.

The aircraft in real-time monitoring of a variety of distinctive features, such as one-touch Auto rotate 360 degrees, gently tap the screen of "spinning", the transfer began to slowly rotate, click again to stop. Two-way voice, of course, no less, which is now a standard home network camera.

Officials rated the level of rotation 355 degrees, vertical rotation of 120 degrees, but because the lens itself has a certain viewing angle range, the actual monitor angle to achieve a 360-degree monitor range is ideal.

Certainly, small turned not only automatically rotating, more is innovation sex of invention has double-click rotating mode, if wants to view picture in the a a specific target, only need double-click the objects, camera that will automatically rotating until the objects is located in picture central location, simple quickly, user again also not need using cross direction key back and forth regulation camera of direction, gently click can quickly completed, called again defined has intelligent camera of operation mode.

Users can also "Favorites" filming location, wanted to see the location simply click the presets to the specified angle of rotation. But go there are still some problems, such as in the App does not have an integrated screenshot function, if we want a screenshot of the original picture quality can only go to video capture.

Do you remember when on the 15 infrared LED light, Yes, transfer is a real infrared night-vision cameras. As a size so small home camera, infrared night vision is not easy, although the infrared night vision effect cannot be compared with professional-grade cameras, but for daily monitoring, picture clarity is enough.

After we opened the alarm screen, if you appear suspicious persons or actions in Mobile App will pop up an alert and send photos to a mobile phone.

Small move to shoot good video upload Baidu is clouds using encrypted format, and not occupy our space Baidu Baidu is clouds clouds of blessings, we can use anywhere on the Web or mobile App to watch videos. On the phone we can clip video, only need to enter a start time and end time can be completed, clip after the completion of part of the clip is automatically good stored in our company in the cloud space.

Clip video, we can see the time stream has two colors, blue and gray, this is the eyes and ears of love in order to save space and bandwidth will change according to the picture to decide whether to store the video screen, if you had been stationary, small move to stop the video, only when the objects in the picture activity will start recording again.

Mobile App also has a public channel for public viewing, select shared video has many canteens or public places, such as the Zhuhai-long jellyfish exhibition. Funny thing was live video also supports the barrage ... ...

Cameras can be set in the shared management of the share mode of the camera, it is set to "public" is a public channel, is set to share secrets with friends to share real-time video surveillance footage.

On this class products has must understand of are know, since used has cloud store service, so on involves service costs of problem, love informer for the machine provides has three species different of service: "7 days Baidu cloud service", and "30 days Baidu cloud service" and "90 days Baidu cloud service", years pay price respectively for 178 Yuan, and 358 Yuan and 999 Yuan.

Our "7 day Baidu cloud services" as an example, although at first glance services bit expensive, but compared to the price of similar products at 300-400, love the eyes and ears of the pricing has been regarded as quite conscience. And love the eyes and ears of Baidu is clouds services compared to a lot of small manufacturers to offer cloud storage, Baidu is clouds have a better performance in the connection stability.

Summary

General for love informer small turned family camera is a Taiwan styling simple, and function compared excellent of household network camera, regardless of is day also is night of imaging effect in with type products in the are considered is compared excellent of, again plus used has Baidu cloud store, again also without for local store space insufficient and concerns, meanwhile you not only can anytime, anywhere of view home in the situation, also can convenient of online view and clip history video.

Although transfer also has some small problems, such as seams, screenshot APP missing one key problem, but afterward, good image quality and low price is the killer app, if you want to purchase a home webcam, then love the eyes and ears of transfer will be one of your sensible choice.

Will publish the first unmanned technology standard in China

According to the latest news, recently in the national intelligent network of car (Shanghai) pilot demonstration areas closed the test area on the opening ceremony, President of China Society of automotive engineers fuyuwu, domestic unmanned technology road map already exists, will be published within two months, it will become China's first unmanned areas published technical standards. Ted Baker Galaxy S4 Case

According to the United States IHS automotive consulting firm released a report predicting that by 2035, driverless cars will reach 21 million vehicles were sold in the world, and China will become the world's largest market for driverless cars, with more than 5.7 million driverless cars.

Faced with such a huge market cake, domestic and foreign auto manufacturers already sharpening.

Intel is working with Israel unmanned technologies makers Mobileye for BMW to develop driverless car technology. Other than the BMW, General Motors, Tesla and other vendors also are customers of the Mobileye. Last year, Mercedes-Benz unmanned f 015 Luxury concept cars in Motion has completed its global debut.

In April this year, unmanned cars start from Chongqing ChangAn Automobile, arrived in Beijing after 5 days more than 2000 kilometers. Hippocampus motor vehicles at last year launched the Moofun mobile Internet ecosystem, covering on-board diagnostic system, maintenance functions, built a platform of intelligent human-computer interaction, and related technology research center was established in the country. Ted Baker Galaxy S4 Case

Although auto manufacturers have put unmanned areas is undeniable, however, this technology is still in its early stages.

First of all, consumers. According to a survey by Volvo, United States there are more than 72% consumers are supposed to keep the autonomy of human driving a car, more than half of the consumers think the driverless cars should also be equipped with a steering wheel. Driverless car no matter what the future development of intelligent, but it cannot replace the human driving pleasure.

Second, supporting laws and regulations is a major obstacle to the development of drone technology. About driverless car accident liability and claims, whether car manufacturers should bear some responsibility, have been unable to clear. And since there is no driver, identified those responsible has become the biggest problem. In addition, the driverless car speed limits also could not reach an agreement, according to Volvo's survey, there are more than 80% of consumers think, driverless cars slow speed limit established by the Government, raising the speed limit to a more reasonable range.

Finally, the technical bottleneck remains no fundamental breakthrough in unmanned technologies. At present, in the field of automatic laser radar technology was flawed, in the event of inclement weather, road signs are likely to be covered up or couldn't, this affects the automatic effect, and high cost of the system, it's hard to commercialization.

https://www.youtube.com/watch?v=ytRZe7TLYYY Fuyuwu said: "the drone a breakthrough is going to be a gradual process, upgrade from active safety technology is half smart, to accomplish all scenes of the pavement completely unmanned. "Obviously, we're in safety upgrades and somewhere between the semi-intelligent, now more and more cars have such as automatic parking, smart throttle brake semi-intelligent systems, however, real completely unmanned, society as a whole and the auto industry still has a long way to go.

The phone module is a good idea or a bad idea?

　　Modular concept was first seen in the United Kingdom Adam Smith (Adam Smith), his book the Haratomi. Adam Smith's view, the Division of labour can significantly improve productivity and to promote the growth of national wealth, later proved true.

　　Modules in multiple areas, such as modular manufacturing and raw materials on the computer industry, programming concept of modular programming, were extensions of thought of Division of labour.

　　A modular collection

　　Modular idea is a simple one. For example, GM's eighth President Alfred · P Sloan (Alfred p. Sloan) founded by the Sloan Management, that is, enterprises in accordance with the product or area divided into modular Division each have a complete functional departments, it is; and General Head Office is only responsible for commanding the overall situation, grasp the decision-making power of major events, this is.

Alfred · P Sloan

　　Programming in the category of modular, in order to maximize reuse. Encountered by the developer in order to reduce the development process for distributed development, version control, dependency management issues, you must code group with the modular form "loose connection", we can collaborate, but not influence each other, and this makes maintenance easier.

　　Computer hardware modularity, it is easier for users to replace upgrades or maintenance. Ordinary users can be targeted to the processor, graphics, memory upgrades, broke down for easy replacement. But on the whole, whether software or hardware management, modular meaning through in an orderly manner, to achieve greater efficiency in collection. [Moschino online shop](https://medium.com/@smartwatch/spring-of-2016-apple-product-launches-7d0242d3bf87

　　Mobile modular attempts

　　Hardware devices, such as mobile phones or computers, because their industry is because of the Division is modular, so in essence any cell phone and computer is a modular product, even the so-called "machine" or "integration body". Modular, but we say, often was not referring to the phone's screen is sharp, the processor is Qualcomm's, but mobile phone design when considering the possibility of consumers going to replace these modules.

Motorola Atrix 4G (ME860) has a dual system, and can expand into portable form

　　First mobile phones module does not as a whole, but the phone itself as a module in combination with other peripherals, which is expanding, like Asus released in 2011 PadPhone, Motorola ME860 are released in the same year using this expanded design.

ASUS PadPhone can overcome size limitations into tablet form

https://www.youtube.com/watch?v=Y0KoC5Xf0Co 　　PadPhone through the flat base inherent in breakthrough mobile phone size limit for greater vision, but also to external keyboard to a certain productivity. ME860 goes one step further, not only has a complete base of notebook hardware, also uses Android + Ubuntu dual-system design, tries to keep the cell phone can really do have notebook productivity properties. Of course, limited to mobile phone SoC performance and ecological problems in software, this design did not set off much of the waves.

　　Development of modular expansion

　　In 2015, losing ground to Microsoft in the mobile phone business bringing the design into the public eye again. But is Microsoft Continuue programme remains much different from Motorola that year because very few applications that support this feature, Microsoft presentation also has to refer to Word, Excel, and his son, and the so-called "software platform", it now appears that didn't help too much busy.

Elite X3 can use HP WorkSpace "run" the x86 program

　　Instead, HP the partners come up with a good software solution. HP Elite announced at MWC Conference this year in X3, also ME860 the notebook expansion base and Display similar Lumia 950 Dock. But the difference is that HP uses application virtualization to software problems.

　　HP HP WorkSpace can be thought of as a remote desktop client, users can directly in the Windows of 10 Mobile system environments running x86 programs. Of course, the x86 not be installed on the mobile phone, but through the server and the mobile phone to establish network connectivity, the interaction of the x86 program "projection". In this way, Elite X3 in the network will have a huge x86 with the support of applied ecology, compared Microsoft's proposal is practical too.

　　Modularization of the phone itself

　　HP Elite X3 mobile phone has been the expansion modules to the extreme. But the problem is that this development also makes cell phone loses its advantage. Compared with single devices such as laptops and flat-panel, "Metamorphosis" after the phones are often more difficult to use than the former, then there is no reason not to use the former?

Google's Project Ara cell phone concept renderings

　　If took computer to do compared, itself module of of meaning is Dang you falls in love with play single game has, on for block better of graphics; falls in love with listening to music has, on for block better of sound card; recently see of small movie too more has, on for block big some of hard disk; if system card have stand, that on put just for Shang of mechanical hard disk into solid hard disk, this is module of real of meaning where.

Yezz Project Ara products on display at the MWC2015 Conference

　　When it comes to modular phone itself, to talk about Google's Project Ara released in 2013 project, its objective is hardware develop a highly modular open source smartphones, but Project Ara because of technical difficulties and market reasons, has yet to launch a mature product. Last seen, it was only last year a little-known Yezz products made by small manufacturers.

LG G5 Chin can substitute different function modules

　　By comparison, LG is more pragmatic, by LG G5 magic of the Chin Groove completed had limits of modularity. Although there is no way to replace the processor, screen and other components, but the extra photos handles with Hifi module also solves the problem of consumer personalization to a certain extent.

　　Summary Moschino cases

　　Mobile modular way is obviously more difficult than go computer, there is not only the technology and size constraints, even existing habits will greatly limit cell phone use. Computer is fixed and mobile phones are mobile, computers are programmed, cell phones are changing all the time.

　　Project Ara even if Google made a full and practical product, but if people are willing to accept "to different scenarios for different parts" of new cell phone usage? Perhaps we can look at the LG G5.

How to build a virtual Empire? World of the senses and human-computer interaction needs perfectly with

Lei Feng network (search "Lei Feng network" public, concern) by: paper from public, "Tung teacher in Silicon Valley", author Steve Gu, du grams University computer Dr, zhiqian in Apple served as algorithm engineers, Google x served as technology competent and future technology assessment, published patent including iPhone of fingerprint recognition and in next generation Apple products and Google Glass of human-computer interaction way, currently engaged in AI related field venture.

Objective

What is real? In the movie the matrix, the computer took control of the human senses of sight, hearing, smell, touch and other signals, allowing people from birth, lived in the virtual world but don't know it. This is a science fiction film, but an imagination.

In 2014, Facebook has $ 2 billion acquisition of Oculus Rift. Google I/O,Google the same year released a Cardboard, a kind of cheap cardboard and cell phone screens you can DIY virtual reality equipment. In early 2015, Microsoft published a virtual and augmented reality headset HoloLens and live demos are amazing. In addition to the major companies and game makers are in virtual reality (Virtual Reality, referred to as VR) field layout, numerous start-up companies are also gearing up, suddenly, VR became a hot topic. While the matrix described in the story is unlikely to occur in reality, VR and VR brings a new experience into the homes of ordinary people, who relish.

VR's great because of its simple structure, low cost, and almost anyone can make your own. Google releases the Cardboard, using the phone's screen as a display, use ordinary cardboard as the fuselage, use lens-focus image, use a small magnet as control switches, sensors on the phone (such as gyroscopes, accelerometers) as head control, use the APP on the phone to display different content and making a scene. Package cost less than $ 1!

(1) human Field of View (FoV, depending) can usually reach 180 degrees. While the camera's angle of view can reach 150 degrees at most. Wide field of view more immersive sense. Figure shown in the horizontal field of view of about 135 degrees, about 60 degree vertical field of view.

However, realistic VR effects still need to be a lot of new technology to help achieve. With a sense of curiosity, us to discuss black behind the VR technology. Coming mainly from the world of the senses (sight, hearing, smell, touch), as well as discuss how to construct the matrix of human computer interaction, achieve an immersive experience. Simultaneous analysis of black behind the technology industry trends and opportunities.

Sensory world

VR equipment is mainly focused on reconstruction of the most Visual and auditory, however this is only a virtual reality technology in the tip of the iceberg. Imagine you are living in the hutongs in Beijing, but wearing VR Helmets around Italy in a corner fruit shop in Florence. You see the fruits shop around ancient buildings, fruit shop owner smile to customers, is not broad enough on the streets of pedestrians coming and going, happy cries of street hawkers into your ears when you smell the scent of fresh fruits, so lend a hand, he can touch the fruit, feel so real. Not only that, the images, sounds, smells, textures, and changes with your mobile, like to visit Florence.

Recently seen some attempts to emulate a variety of sensory VR equipment. In addition to basic audiovisual features, they smell, wind, heat, water and shock. Such a device user experience still needs to be improved, not technically perfect. However, in academia and related research has been going on for decades. Here we count black behind the VR technology.

(Figure 2) obtained through split-screen display different content eye the depth of the image. System parameters including video size, screen resolution, lens focal length, distance between eyes, eyes, such as distance to the lens. In General, the wider the field of view, vision into stronger sense. Wide field of view will cause distortions and pixels of the image to be enlarged. So you need to consider the system design.

Vision

Think two-thirds is used for Visual processing in the brain, then VR must first solve is how to show realistically picture to trick the brain. Current main solution through integration of the left and right eye images to the depth of the scene. Its principle is mainly through the projection scene into the left and right eye, a certain disparity, then through the human brain automatically restore the scene information. This will involve several parameters: Field of View (FOV) determines the time can show how many scenes are divided into vertical and horizontal field of view. Usually wider horizontal field of view, the better (for example, close to 180 degrees), vertical field of view of about 90 degrees.

Screen resolution determines the fidelity of detail. The so-called retinal screen, that is screen pixels relative to the viewing distance is so high, that the human eye can't distinguish curves are continuous or pixelated. High pixels for realistic VR experience is essential. Worth noting is that field of view and screen resolution is usually an inverse relationship. Wide field of view can be achieved through lens design. However too wide field of view will cause the edges of the scene distorts and pixel is enlarged. Designs often have to balance these two points. Delay determines the speed of system response. Generally 24 frames per second frame rate requires a system delay is less than 50 milliseconds or more.

There are also some physical parameters such as distance between eyes, the focal length of the lens and eye distance to the lens and so on, must be considered. For the virtual reconstruction of the scene, mainly through the synthetic objects in computer graphics for photorealistic rendering and then projected onto the helmet wearer's left eye to achieve. So far as the reconstruction of the real scene, focusing on how to collect images and complete record of the geometry of the scene. This can be done through camera (such as the Microsoft Kinect) or camera array. Google launched this year, for example, Jump 16 GoPro is used to create a virtual scene.

Hearing

Voices blend pictures to well-executed site effects. The simplest way is directly from the phone to play a sound.

However the General environment of the sound recording does not restore the full three dimensional information. Three dimensional sound, also known as virtual (virtual acoustics), Binaural audio (binaural audio), using two microphones at the same time a head width of the interval recording live sound. It is complete to save your sound source to a binaural signal amplitude and phase differences (as shown in Figure 3), the audience like they're in the scene. I have tried the system, excellent sound quality, it is shocking. Just Cavalli iPad mini

(Figure 3) using the interval a head from a microphone can be faithfully recorded from the sound source to the ears of the transfer process

Interesting is that perimeter there ear microphone modeling and a skin-like material, which can save the maximum import external sounds the human ear the whole process. Furthermore (as shown in Figure 4), it was built three dimensional sound arrays, 360-degree panoramic sound all input can be, then head of the rotating selectively plays out.

Best application of virtual sound is tailored specifically for a wearer's voice, so you can maximize to restore the feel of the music with high fidelity. The users who, because of individual differences (such as the width of the head, ear shape, etc), virtual sound effect is slightly different, it is difficult to achieve the best play. Need to be based on a specific scenario through a computer-generated voice. Theoretically, if observed scenes, as well as material properties, computers can simulate the sound of all kinds of events and synthesize it in a helmet or VR box in play. Sound synthesis process based on the distance between them, head to simulate a real environment, such as playing a sound.

(Figure 4) left for 3Dio three dimensional audio input devices right further 8 microphone array is used for VR 360 degree show

Smell

How VR box brings "fragrant floating Moon" feel? Smell while not VR to the input signal, but can greatly enrich the experience of VR. Attempt the smell is embedded into the film can be traced back to more than half a century ago (such as Smell-o-Vision). Implemented by means of electronic control odor synthesis also has a history of dozens of years, the more famous the iSmell company.

Simple ideas like this: synthetic scents are usually composed of a stack of small boxes stuffed with spices, also known as scent factory. Each box can be individually heated resistance wire and emitting a smell. Heating multiple small boxes at different odors can be mixed together (Figure 5).

Smell synthesis from practical applications of this technology is still some distance, the main difficulty is how to accurately collection, analysis, and synthesis of any odors in the environment. Simple realization, such as releasing Fireworks, flowers, rain and some basic environmental, already used in 5D, 7D in the movie. Synthesis and complex, such as the unique smell of a shop in Paris, is hard to do.

Among them, the smell also involves the need for regular replacement box problem, it is not convenient for everyday use. I smell in the VR introduced the practice just to throw out. Perhaps in the near future there will be more practical to deploy and simulate the smell of methods available for headset use.

(Figure 5) will smell spices on a separate little box through a separate heat release and mixed

Touch

Touch (haptics) virtual objects can be real, and not only see, but also the "tangible". How to simulate the feel of different objects is a very hot topic. Various touch methods are endless.

The simple touch can be implemented by different frequencies of vibration, the device touches the skin, through the specific vertical and horizontal frequencies and vibrations to simulate the feel of materials under special conditions. For example, vibration is a basic way of touching the grateful. Another example in the latest MacBook trackpad equipped with vibration feedback can be automatically adjusted according to the size of the finger pressure electric current to control the oscillation frequency and amplitude. More complex, according to displays on the screen in real time, adjusting the shock wave to achieve different textures and tactile feedback. Similar principles can be implemented in a VR, such as haptic device embedded into the game in the handle. So that you can screen and different touch gestures to simulate various types of objects.

In addition to handle, and even can experience tactile telekinesis. For example, UltraHaptics, by focused ultrasound to the skin to achieve the "telekinesis slapping" function. Its principles by ultrasonic phase column focusing sound into one point in space to form vibration, shown schematically in Figure 6 left. Another example of Disney Aireal, through precise compression and release air air vortices (vortex ring) to "blow" the surface of the skin. Although vibration mechanism of telekinesis, both use the camera to capture the hand position and make a point of "attack".

(Figure 6) left: Ultrahaptics, by focusing ultrasonic phase array to any point in the space vibrate, and you can adjust the frequency and rhythm have a different feel. Right: Disney Aireal project, sent over a distance of air Vortex waves pound against the skin in a variety of touch. Both projects use the camera (Kinect) to identify the location of the position. Former electronic phase control to adjust the direction of the beam, which sent through motor mechanical adjustment of swirling air.

The latest study, Japan scientists proposed using the laser point to trigger the air plasma, which can be used as a holographic display, and by laser stimulation of touch.

(Figure 7) at SIGGRAPH in 2015 of the show, a group of Japan shows scientists how to use laser excited Plasmas in the air to make holographic displays and touch.

Human-computer interaction

Chat world rich in senses, we take a look at controlling part of the VR. VR helmets in General has an abundance of sensors such as the front camera, gyroscope, accelerometer, sensor, close-range detectors. Such as heart rate monitors, eye-tracking, you can also add device. Sensor gives the new VR equipment of this type of application functionality, and interactive experience.

Head control

Most commonly used is the head control, using gyroscopes to detect two-dimensional rotation angles of the head, and the screen display is adjusted accordingly. Most VR-box to achieve the basic functions.

Gesture control

Gestures can greatly enhance interactive and entertaining, especially important for game players. Gesture control is divided into two categories: the first category is by wearing similar Wii controller glove or a handle to implement gesture recognition; second class directly using the external camera on the helmet by computer vision to identification and tracking of gestures.

For the latter, often need depth like the Kinect camera to accurately identify the gestures. Companies such as LeapMotions,SoftKinetics in VR gesture has many mature demo. In General, use depth camera to accurately locate specific hand positions and good stability.

Eye control

Imagine scenes as your eyes move and change. Like Kickstarter FOVE attempt on using eye-tracking technology to implement interactive VR games. Eye-tracking technology in the VR box or on the helmet are not difficult to achieve, you generally need to box or inside the helmet mount one or two towards the infrared eye camera can be. Other than basic eye-tracking, you can also identify a particular blink is used to control the screen. In addition to the game is beyond their control, eye-tracking and many other applications. Can mimic the biological characteristics of the human eye, where only focus the image in the eye, rest motion blur the image, make three dimensional image display becomes more real, while effectively focusing the image, can also save electricity (see Figure 8).

(Figure 8) from left to right: head control, gestures, and eye tracking to identify and control. Their VR input and interaction.

Heart rate control

Have a heart rate! Heartbeat can reflect the person's current status, such as excitement, fear, relaxing, stress. Test current physiological state VR users can dynamically resize images and sound effects to achieve some real results. For example, when the heart beats faster when a person is in an excited state, you can dynamically increase the images play rate to match the current pace, more violent sports. Also can use negative feedback to adjust quickly to calm down, rest or meditate to help better.

Achieve the heart rate monitor has a variety of ways, such as Apple watches used to be red and green in two close-range of the spectrum of sensors to monitor the heart rate. Heart rate monitors can be combined with the handle on the wrist or on the helmet. Problem is usually the heart rate detectors cannot be effectively and taped to the skin tight, thus slightly moving from some sports will bring readings are not allowed.

Google supports the controversial trans-Pacific trade partnership

Trans-Pacific trade partnership (TPP) is a controversial trade agreement has been criticized by many people, that it limits freedom of expression and privacy, and a lack of transparency. Google has just announced that it supports the TPP. Although TPP has was signed in February by the Obama administration, it remains United States Congress for approval during this period, many businesses, organizations and interest groups came out against TPP, Google acknowledged that TPP is not perfect, but it has follow Microsoft publicly announced their support for TPP.

Google Senior Vice President and General Counsel for public policy Kente·woke TPP described as a major step forward for the Internet. Google's views and diametrically opposite views of the Electronic Frontier Foundation, Electronic Frontier Foundation call is a secretive multinational trade agreements, threatening to expand in the global implementation of tighter intellectual property, overriding the international rules.

Currently, the TPP members include the United States, Japan, Australia, Peru, Malaysia, Viet Nam, New Zealand, Chile, Singapore, Canada, Mexico, and Brunei in 12 countries. Sacrifice of the Electronic Frontier Foundation criticized the agreement, and rights in favour of large companies.

Google praised the TPP and the free flow of information, to strengthen copyright protection and to restrict government access to encryption keys. But it also recognized that there was room for improvement: includes benefits enhance the transparency of the negotiation process, including the establishment of innovative, Internet-friendly trade agenda.

Before you discuss the future of video, how did we get this straight video realization

"Editor's note" the writer Wang Rui, VR senior industry practitioners.

Perhaps is this a year or two, with the surging of VR boom, "Panorama" was the word onto the table over and over again, as "virtual reality", "real 3D", "360-degree", "720" and other names, so are a lot of people as the main word for a form of virtual reality contents.

Indeed, lack of VR contents is now a growing number of developers and business groups concerned, and panoramic pictures and videos, as well as infancy VR movies, will undoubtedly become a very good way to landing. It does not need too much of the ability to interactively study costs and at the same time, gives the viewer the full immersive experience, as well as offline rendering and photography get the best effect.

So, panoramic view the definition and the implementation of what is, how to build a panoramic content? This article will try to tell it from several different key perspective, expects to be able to wave upon wave of creators who help.

1, projection methods

Panoramic photography is not what a new concept, in fact, it can even be traced back to the 12th century of the Night Revels of Han Xizai:

Of course, this is not a truly immersive experience, even if we give this picture of long rolled up into a cylinder, then stood watch in the Center, and still find something missing, that's right, an obvious seam, as well as both the head and foot area blank.

This problem is very simple, because the Song dynasty who did not intend to put this picture into immersive experience--this is nonsense – the real reason is, of course, picture corresponds to the physical space and the view did not reach the level of full surround, which is horizontal (latitude) 360 degrees vertically (latitude) of 180 degrees. That's right, at this point, you must think of this picture:

Like the world map on the wall may be in your home already for some years, perhaps after moving on to the University you've never even look at it, but it meets the needs of a panoramic picture all the conditions, you put it in all kinds of VR glasses to watch it, just like in the whole world around.

This correctly around the physical perspective on real-world scene to a 2D image, and the ability to restore to implement immersive VR glasses to watch the mathematical process, called projection (projection).

And that seemingly mundane world map photo, use a common called Equirectangular projection, it is characterized by horizontal field of view image size can get a well maintained, and the vertical angle, especially near the poles of unlimited dimensions will happen when stretched.

Stretching for this form of projection in the figure below more clearly reflected, note the dome texture changes, the more near the top of the screen, the more severe the distortion. Fortunately, the VR helmet and application is the meaning of the apparent deformation of the revert to the full view of the screen content, which allows users to have a sense of immersive Surround.

Panoramic image projections, however is much more than this one, such as the recently released Ricoh Theta s Insta360 panoramic camera, using a more simple and effective alternative projection strategy:

Through its two fish-eye camera output image, each covers 180 degrees of the horizontal and vertical field of view angles, and two output "buckle" together is full of immersive Surround view.

Of course, known as Fisheye projection, generated 2D images in fact distort are more serious. By way of image reprojection process when it was displayed in a VR glasses to transform it, limited by the image sampling frequency (or generally say, limits on pixel size), restoring such distortions would exert a measure of image quality loss and, therefore, may cause the panorama the decline in the quality of the content itself. Moschino Case

In view of this, as an important host of panoramic content matrix, projection image (or video) not only should contain complete images of all content, to avoid too much distortion projection VR glasses in order to avoid loss of quality.

So, apart from two projections set out above, there are more options you can choose to do? The answer is, of course, and plenty of it! Moschino iPhone 5 Cases

Like the Mercator projection (Mercator), along the axis of the tensile deformation smaller than Equirectangular, corresponds to the actual proportions of the scene more realistic, but expresses only the contents of about 140 degrees in the vertical direction;

Another example Equisolid projection, it was also called "asteroids" or "720" panoramic views, it can even be a 360-degree vertical horizon show, but only if users don't care about huge distortion may lead to loss of quality:

So, is there a projection generated picture, is capable of covering at least 360 degrees horizontally and 180 degrees vertically and there is no distortion of the picture?

The answer is: no distortion of single image projection method, does not exist. However, if the results of the projection screen is not a single image, there are:

If you happen to be a graphics or virtual reality software development practitioners, this picture should be very familiar to you, this is the Cubemap (cube).

It is equivalent to a cube made up of six image mosaic box, if we assume that the observer is located in the center of the cube, each image corresponds to a surface of a cube, and equivalent in the physical space the horizontal and vertical are 90 degrees FOV. Viewers are surrounded by six pictures in the Center, eventually sight range can also achieve the same level of 360 degrees, 360 degrees vertically and are absolutely without any distortion of the frame.

Is as follows:

This is a very good projection results, and if you happen to know how to use offline rendering software or plug-ins to produce and output a panoramic content, this must be the most appropriate choice. However, during the actual shooting is almost impossible for us to record this cube map, simple reason – our existing equipment to do it.

2, joining and integration

If said has six Taiwan camera, they of FOV angle was strictly qualified for level and vertical are is 90 degrees, then made a meticulous of bracket, put this six Taiwan camera firm and stable to installation to bracket Shang, ensure they of Center points strictly coincide in with, and their towards a direction--such words, output of image may can just meet cubic figure of standard, and can directly using.

However, regardless of camera lens of photographic area, focal length parameter (and so calculation get of FOV depending on field angle), also is bracket of steel body structure design and making, are cannot ensure precise to reached above requirements of parameter, several mm of optical or mechanical errors seems harmless, but for fit of cubic figure image for, must will in eventually rendering of immersed type scene in the left a article or more article obviously of crack. Mention also supports vibration problem occurs during exercise, as well as the camera lens focus shift problem of aging, these seemingly small trouble hard enough for us to just build a physical model of ideal come to naught.

Ideal and reality of gap so of big, fortunately we also has solution of approach--Yes, if in mosaic of place left enough big of redundant, then right recognition and processing two Taiwan camera picture coincide of regional, such not on can do six site picture of output and composition panorama content has did--and this is panorama content making of another a big magic, image of mosaic and edge fusion.

Below is a 360Heros series of panoramic cameras.

It uses 6 GoPro Sports cameras and a stent to help complete filming, six cameras were headed in different directions, if we adopt the 4X3 wide angle setting, horizontal and vertical FOV angle of about 122 degrees and 94 degrees.

Panoramic video mosaic reads six camera inputs and output software streaming or video file, and set them in the physical location of information on the bracket (or direct access to a digital camera records the information). So that we have enough video content covering the entire FOV.

As we described earlier, because there is no precise alignment, so need to be on the point of the view of each camera to provide the necessary redundancy, thus obtains the video there is a certain overlapping relationship between each other, direct output when panorama, there may be significant overlapping regional or wrong side. Although currently several common of panorama video processing tool, such as VideoStitch,Kolor, has must degree of automatically edge fusion function, but many when we also is inevitably to himself manual to CD cut and adjustment these edge regional (for example Xia figure in the using PTGui to for the site picture seams of Amendment), takes picture quality more high or orthodontic change small of edge regional, and ensure picture Zhijian is strictly on align of.

Such work is time-consuming and there is an important prerequisite, is used as the input source image must be able to cover a 360-degree view and there are redundant.

As the we zhiqian by calculation of, if used six a camera assembled of way, so each camera of FOV angle not should is less than 90 degrees, for GoPro Hero3 series camera for, at must used 4x3 of wide depending on domain mode, if is 16x9 of wide high than set, so vertical direction of FOV angle is may cannot reached requirements of numerical, then produced "anyway are mosaic not Shang" of problem--certainly we can through in bracket Shang adjustment all camera of towards angle, Or increase the number of cameras, to avoid this problem, but no matter from which point of view, close to the 1x1 aspect ratio wide field camera is a better choice.

https://www.youtube.com/watch?v=CvP57QmJe7Y If only to output a panoramic picture, then the above steps usually have more than enough, don't need to think about more things. However, not moving pictures is hard to get people wearing VR helmets, Wah yelled can see flames, or ghosts haunt the dynamic scene more exciting. If you are thinking about how to make the VR movies, then there is a problem I must mention, that is-

Synchronicity – in simple terms, is how all the cameras in your hands start precise guarantees, as well as in the process of recording frame rate of consistency.

This does not seem to be any problem, however, if the start time of the two cameras is inconsistent, will directly affect their alignment and stitching results-even if the scene has a lot of dynamic elements or camera position in the process of change, the results may be out of alignment. Therefore, require the involvement of a large number of cameras at the same time panoramic work, Sync start synchronous recording needs become more important.

Basic hardware to solve this problem, you can use "phase synchronization lock" (Genlock) technology, passing through an external device run time code to control the camera's synchronization (typical for example Red One professional movie cameras). Of course, not all cameras have dedicated Genlock interface, in that case, can also be considered traditional or look slightly "shanzhai" method of synchronization, such as unfair on the road, with a roar ... ...

When the shooting began, actor with a snarl, or whack smack. And then the process for stitching, find each video corresponding to the roar of time nodes's place as the synchronization starts, and then the stitching of panoramic video. This method, although there is no accuracy whatsoever, but again it did not cost anything extra cost but ensures basic synchronization after start, then subtle adjustment and video slot, but no doubt considerably simplifies the difficulties of post-production.

Similar methods as well as to all the cameras covered with black cloth, and began to shoot fast-draining, and so on. Anyway on the premise of hardware cannot be fully equipped, that is, eight each time.

3-d and pseudo-stereo

Careful you may have discovered, all discussed before shooting panoramic video ignores a vital point: regardless of the projection, generated only a 360-degree panoramic content, on the PC or Web-side to watch, of course without any problem, but if you want to enter on a VR helmet-mounted display, the result is probably not correct. In order to assign a picture to icing on the cake and presents to the human eye, the content we provide separated around eye level display mode must be used:

It seems only to be a copy of the original panorama, but careful observation, location near the border of the frame you will find around the contents of the screen there is a certain amount of offset. Because people's eyes there is a difference of perspective, eyes see certain differences in the images, and through the brain of the solution can be solid feel. Scenes from closer to the human eye, this disparity is more obvious, the scenery in the distance or relative does not have a strong sense of depth.

Any existing VR glasses required a structure designed to ensure that the wearer's left eye and can only see half of the screen, which is seen after separating the left and right eye images, respectively, so as to simulate the human eye works.

This case, panoramic view of filming equipment also corresponds to the need to make some changes, such as the original 6 cameras to 12 cameras, each direction has left two cameras are responsible for shooting; support forms are so entirely different from the original design (shown in 360 Heros3 Pro12, uses 12 GoPro sports camera).

Software for stitching and fusion, and nothing special needs to be done, just be twice six video stream is read, output two different panoramic video, one for each left and right eye images. Then through tools and applications will merge them into one picture.

Of course, different way there, such as from 2011 all shook the Kickstarter to raise, but until now VR panorama fire but still no Panono issued on schedule, its design principles are uniformly distributed in the sphere of 36 cameras to capture, mosaic and the panoramic views of the left and right eye image.

The designs seem to be pulling up, it is actually the same: 36 towards the different camera image, superimposed on the cover with 360-degree vertical 360 degree field of vision and scope, and will be able to cover it twice! Attitude plus their precise structure design and installation, so that you can calculate from the inside out after stitching panoramic images, and in accordance with the standard output of left and right eye images and video streams or files that can output the actual resolution is considerable.

And similar to the Bublcam (four ball super wide-angle), Nokia OZO (8 ball lens) and Jaunt in the research and development of products and so on. They all have the ability to output stereoscopic panoramic content in the form of.

Of course, the bad case, we still have a choice, is created a stereo model all by himself ... ...

To copy the original panorama into two halves, one offset to the left, another right, then do a mild perspective transformations (to simulate the deflection of angle of view). That it constituted a "solid" picture in many of the cases have some stereo effect of cheating, but near the scene, or the left and right eye images of the scene exist when blocking (such as analog face pasted on the door, one eye of latch blocking scenario), you will have obvious flaws. Of course, for contents at silly stages of the VR panorama enthusiasts, this is not a serious problem for the time being.

Tesla with the latest on-board operating system Version 7

　　How to make a car wheel, for automakers now is focusing on the issues, is also true for Tesla. Can say that from the perspective of the scientific and technological content, Tesla is the automotive sector, one of the leading figures. And the car released their latest Version of the operating system 7, it can be considered a major step in the field of self-driving cars.

　　Of course, this time, Tesla drive technology is still very limited. Includes two aspects: automatic steering (Auto Steer) and automatic lane changing (Auto Lane Change) the autopilot functions. In addition, the changes brought about by the upgrade of the operating system also includes the Model s and x 17-inch Model in the center console are displayed. Including the new dashboard, larger Windows and new clock display. Hello Kitty iPad case

　　This time, the most important Auto Steer function, is basically an advanced lane departure system vehicles, which can be adjusted independently keep driving in the driveway. However, this does not mean that motorists can afford to ignore, when in case of emergency, the driver needs to be able to take over the operation at any time. When the driver took over operations, car driving program will automatically shut itself down, and on the hand control back to the driver of the vehicle.

　　Auto Lane Change feature, it was modeled on the car body configuration of 12 cameras and sensors for Lane identification and observation of the position of other vehicles. And the information is fed back to the system, autonomous security operations by the system.

　　Meanwhile, the Executive musk said Tesla: Tesla would take about 3 years to complete a full autonomous driving technology, believe that cars achieve intelligent autopilot, can be achieved in the near future.

Brush face Out to unlock the phone early domestic ATM brush face to get the money

　　This is the age of a watch face, by swiping a face on top of the life there. Brush face not only plays an important role in the social life, will also play an important role in human-computer interaction.

　　In fact, Android ice cream sandwiches, but things have changed, there have been many Android phones support facial recognition to unlock.

　　Now, people don't just brush face to unlock the phone, you can also brush face to get the money, also through face recognition technology.

　　China Merchants Bank has formally apply face recognition technology to the ATM machine, users can brush his face to get some money, no longer need to use cards to withdraw money. For those who often get their money after the completion of, ranging from card and turned away people is very good, or at least prevent the money being stolen.

　　It is understood that the user at the time of withdrawal, ATM system will capture the user's photo, and then compare with photos of Bank of reliable sources. After validation by direct withdrawal once again, enter the mobile phone number verification, enter the amount and your password, will be able to withdraw, one-day limit of 3000 Yuan.

　　Because this is a face recognition technology used in the ATM for the first time, belongs to a new business, so as to ensure security, banks still need limits.

https://www.youtube.com/watch?v=uY-8c65cQPk 　　Head Office of China Merchants Bank information technology department General Manager Zhou Tianhong pointed out that brush face no card withdrawals, withdrawals are based on improved security and convenience. According to him, with the existing "free card withdrawals" business than brush face withdrawals easier, without a withdrawal card users through mobile phone banking appointments, and brush face withdrawal support withdrawals at any time; in terms of security, face recognition error rate has reached one out of 10,000, in addition to mobile phone number and password protected.

　　Zhou Tianhong, face recognition an imagination is bigger, effectively identify customer, a large number of financial services can implement scenario. In counter applications for customer identification, for example, can direct our financial marketing services. He said pedestrians face recognition technology has been polished for a long time, then there will be applied to the mobile terminal. Paul Frank iPad Air Case

　　ATM now brush his face can be accurately identified the twins, lose weight users, however, identify cosmetic groups difficult.

　　CMB experiments, even twins, or after weight loss customers, are recognized by the barrier. China Merchants Bank said in Shenzhen and Wuhan sample test found two sets of twins, the results are accurately identified. It is understood that this recognition is weak bone shape difference and distance between key points. In addition to a bank colleague who lost 40 pounds, face recognition technology is also well recognized. However, Hutchison said, the entire capacity of the customer, the machine may be difficult to identify.

Google self-driving without human intervention would result in 13 accidents

　　Google self-driving car project monthly report showed record data according to the onboard computer, this driverless car in between November 2015 and September 2014, 13 human intervention, or there will be 13 accidents occurred. In June 2015, Google decided to open its self-driving car project, provide a transparent policy. Its initial report, AI of the car quite well in avoiding accidents most accidents not related to computers and AI, most of them are caused by driving or other traffic participants.

　　At that time, the company also agreed to monthly the monthly reports of the project. A few days before the December report, including car AI disconnect and switch to the manual mode all the records, event records forcibly seized control of the car and driver.

　　According to Google's telemetry data, 272 times this happens, mainly because AI failed to identify the traffic situation and take appropriate action. When this happens, the driver needs to put their hands on the steering wheel, and take appropriate measures to get rid of AI traffic situation is not recognized driver need manual steering wheel with an average time of 0.84 seconds. Flawless cases

　　In addition, there are 69, the driver immediately took over all control of the car, such as traffic violations, cyclists and pedestrians to cross the road, and does not correctly identify the traffic lights. Flawless iPhone 6 case

　　Google headquarters, analyzed the data and concluded that 13 of them using powerful simulation software if there is no manual intervention will result in a traffic accident. Includes 2 cars collided and traffic cones, 3 car collided with another vehicle. Google says May 13 accident occurred, 10 were AI technical errors, while the other three due to other traffic participants.

Abandoned walking sticks for the elderly is a pair of "roller shoes"?

Home old man, my parents ' generation are especially worried about the old man fell, because the elderly fall, the consequences will be particularly severe, the old man can't afford to fall. Common to the elderly with tools on the market have crutches, walking frames, and so on.

From Israel, a start-up company B-Shoe a new path, the launch of a new tool, that's smart shoes, its biggest feature is that it can prevent elderly falls.

Why the elderly will fall down?

First of all we will talk about a problem, and that is why elderly people fall? When the man lost his balance and fell back, our bodies will respond quickly, to take a step backwards, so as to maintain balance. However, due to increasing age, older persons action became slow, reactions slow gradually, to take a step back and actions often don't have time to do and fell.

It is actually a pair of "roller shoes"

B-Shoe intelligent shoe equipped with a pressure sensor, drive unit, a rechargeable battery, microprocessor and the integration of the advanced algorithms. B-Shoe intelligent back heel inside the track, when the old man lost his balance and was detected, it will fall back, track will start immediately, the old man's foot backward to move some distance, in an effort to regain balance.

https://www.youtube.com/watch?v=CvP57QmJe7Y In view of this, B-Shoe shoe is more like a pair of "roller shoes" will slip to a specific location at the specific time, helping the elderly to regain balance.

Join so many parts, the shoes are really not heavy?

Installed in the shoe so much, is it too heavy? On this point, B-Shoe said that this is not a problem, because these parts are used in the shoe is lightweight.

B-Shoe intelligent old man shoes sale right now?

B-Shoe intelligent old man shoes are still in the prototype stage, prototypes are already in Israel famous Gait Laboratory at the hospital laboratory for testing. B-Shoe Company is seeking investment and is expected to enter mass production in 2 years.

Small series of Lei Feng network reviews

Little also think, but they are expected to be heavier than ordinary shoes, after all, joined so many parts. B-Shoe shoe is the most should pay more attention to its safety performance. These shoes just in case exhaust fan is out of order, tracked their own began to move, the shoes are really into skateboarding shoes. But is no doubt, the shoes are a good idea, and obediently waiting for the product.

For more cool intelligent hardware information, please pay attention to odd public number (woaiqiku), in odd public key, you can buy, and I'm not gonna tell you, register as a network of Lei Feng (search for "Lei feng's network", public interest) members can obtain the benefits of super well.

MWC 2016 | Zuckerberg speaks for Zhang Jiajia, "from your world pass by"

Virtual reality (VR) can offer a whole new world for us, but wearing VR devices have also been isolated from the outside world at the moment.

Samsung last night on the new Conference, Facebook CEO Mark Zuckerberg, jiuzhanquechao, became the Conference's lead. Him from the Hall pass, but standing on the stage, only to be 5,000 attendees at the scene discover and "Pa Pa Pa" pictures. Audiences at the time wore a Samsung VR Helmet Gear VR, watching the Galaxy S7 released the video.

Spectacular, was making one's flesh creep. Like Gizmodo reporter said, "feel like I look better, have to wear a helmet in the virtual experience", and virtual content in a place not far from his.

When there's a real person by your side, you can't find, makes one think of teacher Zhang Jiajia's bestseller, from you all over the world pass by. You wore VR helmets, the world, Miss Zuckerberg.

We cannot deny, VR in the next couple of decades will become a part of everyday life, like a cell phone. In addition to Gear for Samsung VR Conference was held, also resorted to a listing in the second quarter of the Gear 360 panoramic camera. Another manufacturer HTC has announced that in due course, consumer Edition HTC Vive set priced at $ 799, the market on April 1. Addition to LG to get hot, and LG launch LG 360 panoramic VR and VR glasses camera 360 Cam. VR Shinecon

Also before the birth in OxygenOS, after one-and-mobile domestic version, mainly carrying the Color of an old master OPPO OS also provides MIUI millet, and Cyanogen ordered by CM. While the international version is mainly working with CM.

Over the years, and see especially important overseas markets, and that's why its established cooperation with Cyanogen. The introduction of OxygenOS selection, mostly wanted to force overseas. It can be said that OxygenOS's success or failure will be a matter of one plus one mobile abandoned in CM beyond the road is smooth, OxygenOS for an added importance.

However, OxygenOS can help a plus phone in international markets in the future?

One-and-out with its own ROM: cooperation with the CM due to abort

Some insiders said: it is because of one and will not, do not want to start doing their own ROM, in order to ensure the user experience, choose to use a relatively sophisticated color OS as well as CM, to ensure user experience

A plus phone achieved good results in overseas markets also benefited from CM. As we all know, CM by the global Android enthusiast favorite, plus ride the East wind of CM in North America, the market had a good performance in Europe. However did not last long, looks perfect for a plus and the CM, it seems at the end of last year, there have been some unpleasant.

Last December, one plus mobile phone ready to enter India market, but Cyanogen's sudden change, making one and India tour were hampered. The reason for this is a combined declared India market, Cyanogen and India signed an exclusive local manufacturers Micromax exclusivity agreements, and launch of the Yureka carrying CM phone. Micromax has a CM in India after market exclusive, they filed a lawsuit with the Delhi High Court, considered a plus against their interests, and ban in India engaged in any sales-related activities, while the Delhi High Court also agreed with the lawsuit.

After going through this lawsuit, one plus and Cyanogen cracks in the relationship. One plus was also determined to reduce dependence on CM, thus promoting independent ROM development speed and plans to use the new operating system to replace the existing CM. Moschino N4 case Moschino for Note 4

Some insiders said cooperation with CM suspension is because the exclusive cooperation with CM, not broken. Will continue to be updated also after CM, CM will have more partners. Add overseas shipping pre-loaded OS system from CM to oxygen.

One plus OxygenOS design: 99.9% on Android native

However, after the release of OxygenOS, a Netizen joked, adding, this operating system 99.9% is based on the native Android, how can actually claim to be developed? This is where OxygenOS criticized.

OxygenOS based on customized Android 5.0 Lollipop was subtle, and its overall style and original Android 5.0 is not much different. Because the OxygenOS is specifically designed for overseas markets, OxygenOS chose to maximize retained the Android native features, including application preset package for Google services, Docs, Slides, and Sheets, and Keep, Wallet etc, the camera uses a Google Camera, photo album contains cloud backup feature is Google Photos. Even after booting the first screen of the application folder and the native Android 5.0, into Google, Create, Play three folders plus Play Store.

In addition, OxygenOS CM was also retained in some nice features, such as virtual buttons and post screen physics capacitance press, put out the wake screen gestures are kept down, application-specific functions. In addition, the one plus is an exclusive custom, one of the biggest feature is the drop down shortcut settings in the notification bar, such as Wi-Fi, mobile data, Bluetooth, flight mode, flashlights, etc, allows users to customize and adjust settings, choose settings for display.

But for a ROM, Liu Zuohu describes his design philosophy. In his view, "currently on the market most of the ROM in the Android to make them blindly like iOS, this is a very old idea. And iOS mobile operating system is not necessarily the best user experience. So far as the Android, version 5.0 of the experience has been very good. One plus one will be optimized Android 5.0 based on ROM, inherit and develop the Material Design concepts ".

Why did OxygenOS into the atmosphere: no one's soul

OxygenOS 99.9% keep the Android native characteristics, the main reason was to meet the needs of overseas customers, minimize after replacing the operating system the user's loss. Before you phone a popular in overseas markets, one of the main reasons benefited from CM, therefore a choice among OxygenOS retains some features of CM, the goal was to keep these users.

However, it is precisely because of this policy, makes OxygenOS no longer pure. In OxygenOS body, we can see both the Android and 5.0 CM's shadow, it has Android 5.0 native skins and services, and integrate the CM and one plus custom features. This makes OxygenOS not his soul, nor reflect one plus "not on" brand culture.

Furthermore, third-party ROM competitive, mainstream third party ROM is depends on its advantages in conquer the world, a featureless ROM will struggle to survive. Such as CM pure and smooth, MIUI changed with personality and Flyme briskly concise ... ... Compared to the mature third-party ROM, one plus OxygenOS has just started.

But for domestic users, as the OxygenOS preset Google's primary service, cannot be used at home, may be acclimatized lead to bad experiences. However, one plus subsequent H2OS aimed specifically at domestic users will also be introduced, may solve these problems.

One plus was first created "not on" brand culture, on the independent ROM, however, one plus one selected "on", eager to get rid of dependence on the CM on the one hand, on the other hand is designed to meet the needs of overseas customers. Finally, one plus one will be the biggest problem, that if to retain users. Therefore, some users chose to add fancy is, after all, CM, and one plus one will replace CM with OxygenOS after, will was abandoned by user bad to say. Do not take one-and-done a very "on" the ROM, so OxygenOS or difficult to form the atmosphere.
