Yu Chengdong： Huawei’s smart driving is spot, not futures

Pacific science and technology informationAt the Huawei HarmonyOS Eco-Spring Communication Meeting held today, Yu Chengdong, managing director of Huawei, CEO of BG and chairman of BU, a smart car solution, said that "Huawei Smart Drive is a spot, not a futures, but the best spot", which triggered a heated discussion among netizens.

It is understood that Huawei’s advanced intelligent driving has been tested and applied in some cities and scenes, such as urban roads, highways and parks. It is equipped with the M5, M7, M9 and S7. It can realize Huawei ADS high-order intelligent driving assistance without relying on high-precision maps. In the future, with the continuous progress of technology and the gradual improvement of regulations, Huawei’s advanced intelligent driving is expected to be applied and promoted in a wider range of fields and scenarios.

Huawei’s advanced intelligent driving is a very advanced and potential automatic driving technology. However, the current automatic driving laws are not perfect, and the automatic driving algorithm still needs further iteration. The public still needs to treat it rationally and choose and use it carefully when facing the intelligent driving function of the car factory.

From car projection to headlights, why do you always want to watch movies in the car？

This seems to be a question without any doubt.

The journey is long and the driving is boring. People who want to rub hemp and play cards in an ox cart naturally have the motivation to continuously enrich the entertainment functions of the car. As one of the highlights, movies are constantly chanted by drivers and passengers.

All right, meet you. So there is a drive-in theater with FM radio and outdoor curtain, a second-best radio drama, a car mobile phone, a flat bracket, access to resources from major platforms, and a car-mounted high-definition big screen-now it’s time to compete for the screen size and quantity, one, two, three, until they are connected together.

However, with the continuous development of "out-of-car" technology (such as naked-eye 3D, VR/AR, etc.), the larger car screen can no longer satisfy people. As a result, OEMs have made great efforts to (da) follow (kai) and (nao) dong, and the "black technology" around watching movies and other entertainment projects has followed.

VR/AR stream: Audi

When it comes to black technology players, Audi definitely belongs to the first echelon.

At the 2019 International Consumer Electronics Show (hereinafter referred to as CES), Audi demonstrated its new generation of in-vehicle entertainment system, which can match the virtual entertainment content in real time according to the movement of the vehicle, and the rear passengers can experience the visual experience of the 4D cinema while the vehicle is driving.

The system is developed by Audi Electronics Venture, a subsidiary of Audi, and is responsible for the commercialization of VR technology through an open platform. In the future, the company will also provide their services to all car manufacturers and content developers. When the car is equipped with this in-vehicle entertainment system, the rear passengers can experience movies, video games and other in-vehicle interactive content in real time by wearing VR glasses.

The system can be experienced on Audi’s first pure electric product, e-tron. With the help of the Internet of Vehicles and VR glasses, when the vehicle is stationary, the rear passengers will stay in the virtual spaceship. When the vehicle accelerates, the passengers will feel the state of the rocket taking off, and all the movements of the e-tron will be synchronized in real time and mapped into the virtual experience space.

Specific to commercial applications, Audi said that the system is planned to be introduced to the market within three years.

Ideas are always beautiful. I have two biggest concerns about this technology. First, whether the content can keep up, it seems that if there are only a few films and scenes, it is easy to keep eating ash with the freshness.

Second, it is whether you will get carsick.

Window flow: modern

Also at CES, Hyundai Motor released a new virtual space touch technology, which can be used to "eat" with the window display technology, so that the car can become a small "cinema" with a slight finger movement.

In the autonomous driving concept cockpit named Autonomous Driving Interior Concept, not only the physical buttons are eliminated, but also the touch screen is eliminated. You can make a simple action of "pressing" with your fingers in the air to control the vehicle system. In manual driving mode, the window will be transparent; In the automatic driving mode, the window will automatically darken, and the surrounding conditions of the vehicle will be displayed in the form of video. When the video is projected on the window, the window will become the big screen of the car, and you can enjoy a real three-dimensional surround movie at this time.

Vehicle projection stream: Ford

Compared with the above two cool sci-fi ways, Ford’s scheme is very grounded.

It recently applied for two patents.

The first is a patent called "Portable Entertainment Support System", which will be used in the carriage of pickup trucks (such as Ford’s famous F-150).

In the patent drawing, Ford wants to add a pull-down screen and speakers on the higher crossbar, while the projector installed on the lower crossbar can turn the carriage into a mobile cinema. In addition, the TV can be installed on a higher crossbar through a common wall-mounted kit. If the truck is going to run, it is easy to remove the crossbar and store everything in the compartment.

It seems simple, but many technical parameters need to be considered in the design.

The second is a projector installed on the rear fender of a car, which can project TV or any video onto an external device. Imagine that when the sun goes down, everyone will gather around the campfire, the owner will open the tailgate of the car, and then everyone will watch movies or play video games under the stars.

In addition, the design can also provide external lighting. For example, when night falls, the projector can project light onto the table, so it is very suitable for camping or playing in the wild.

In China, car projection is not a high-frequency requirement, but with the gradual popularization of go on road trip and the increasing demand for travel and entertainment, more and more people will need this function in the future.

3D stream: jaguar land rover

It is reported that Jaguar Land Rover Group is developing a new head-up display HUD, which can play 3D images in the car. This new type of HUD can not only project real-time information like the traditional HUD, but also allow passengers to watch 3D movies safely. "Head and eye tracking technology will track users’ positions to ensure that they can see 3D pictures without wearing optical/shutter 3D glasses or providing a separate screen for each passenger."

The concept of 3D cinema also reflects Jaguar Land Rover’s confidence in the future sharing and driverless trends.

Many suppliers are also keen on the research and development of naked-eye 3D, holographic projection and other technologies. For example, Bosch recently launched a brand-new 3D display product. The display screen can generate a very realistic three-dimensional effect, which allows the driver to capture the on-screen information more quickly. When parking, the realistic display screen allows the driver to judge the remaining space between the vehicle and the wall more intuitively and effectively. In addition, naked-eye 3D can also play a big role in the field of map navigation.

These technologies will produce amazing results when applied to entertainment systems. However, like other forms, it may encounter the problem that the content cannot be updated quickly with technical means. At the same time, when the picture and content are more complicated, it is also a test for the hardware and computing power of the car machine.

Headlight flow: Mercedes-Benz /WEY

This is a school whose concept is well understood but whose technology still needs to be worked hard.

Simply put, it is to let the traditional car headlights evolve and evolve again until it can be used as a projector-that is, the application of lighting digital projection technology in car lamps.

Nowadays, Mercedes-Benz’s Digital Light technology and domestic brand WEY’s intelligent pixel headlight concept have been able to project words, traffic signs and more complex graphics.

At present, the main application of this technology lies in the safety assistance and reminder during driving. The entertainment function is just an adjunct to the icing on the cake. However, who can guarantee that a very interesting new gameplay will not be born with the breakthrough of a certain technology in the future? After all, when it comes to headlight projection, many people’s subconscious reaction is still "that can be used to show movies."

Advantages and disadvantages of watching movies in the car

The benefits are obvious. It is not limited by the region, has good privacy, can kill time (especially when the electric car is charging), and can also coax children and so on.

The disadvantages mainly focus on the safety problems during driving-it will distract the driver’s attention to some extent. Before autonomous driving is realized, greedy eyes will also be a big problem. After all, people sitting next to you laugh at pigs from time to time while watching movies and drinking coke, but they are driving hard, which will inevitably lead to psychological imbalance. Autopilot. Come on.

Of course, some people say that watching movies with an electric car will consume electricity and shorten the cruising range, so it is suspected of raising the bar.

It can be seen from all kinds of "schools" of technology that the application of technology is becoming more and more diversified-one technology is no longer specially designed for a certain scene, it can be used for entertainment, and it can also be used to improve security or information systems. With the "mixing" of technology, multiple systems in the car gradually blend into an organic whole, which is no longer so distinct.

And this may be the performance that the intelligent era is about to open.

Is it really affordable or is there a trap？ Is free broadband really a good deal？

　　Handling a mobile phone number can not only make phone calls and send text messages, but also bind broadband accounts and get free broadband — — This "mobile phone package+free broadband" model sounds practical and cost-effective, and is favored by many consumers. Mr. Liu, a Shanghai citizen, chose a similar communication package. He told the author that the primary reason for his choice was "feeling very cost-effective".

　　However, some users said that without their knowledge, the free broadband that was handled a year ago began to be charged quietly, but it was difficult to cancel it. Is the "free broadband" package really affordable or is there a "trap"? What problems should consumers pay attention to when choosing this kind of business?

　　"Package" is not for everyone.

　　Data show that at the end of 2018, the number of fixed Internet broadband access users in China reached 407.38 million, an increase of 58.84 million over the end of last year. Free broadband and preferential packages vigorously promoted by major operators are indispensable. Operators seize market share through free broadband, which makes giving free broadband to mobile phone packages increasingly become a mainstream communication package type. However, when different consumers choose this kind of package, the experience is very different.

　　Yan wang, who lives in Zhengzhou, Henan Province, has been using a mobile phone to bind broadband services for three years. "The free broadband given in the mobile phone package is no problem to use, and the mode of automatic monthly payment also provides convenience for users." Yan wang said that when he first moved into his new home, he packed a set meal with the recommendation of the salesman. "Do broadband alone for a month to 40 yuan; Tied together, the telephone bill and broadband add up to 68 yuan every month, and I feel that the price is still very affordable. "

　　However, Cui Le, a junior at Wuhan University, is not satisfied with the same "free broadband" business. Under the propaganda of the communication company, Cui Le and several roommates handled a set meal together. However, after a period of use, Cui Le found that the given broadband service was not suitable for campus use: the database purchased by the school could not be used, and the teaching platform could not be logged in. But at the beginning of the business, no one told them that such problems might occur. After several months of continuous deduction, Cui Le and several roommates felt "lost" and had to go to the business hall at the same time to unsubscribe from the business and cancel their mobile phone numbers.

　　Be careful of "default automatic renewal"

　　The author’s investigation found that consumers’ dissatisfaction with the "mobile phone package+free broadband" model is mainly reflected in the following aspects:

　　Free broadband is difficult to meet the needs of specific groups. Like Cui Le, many students in school have been troubled by the incompatibility between free broadband and campus network, which leads to the helplessness of going to the library to "surf the internet" when there is broadband in the dormitory.

　　Most free broadband packages are automatically renewed by default, which is unreasonable for users who don’t want to use broadband continuously. Netizen "john young" vomited on the social network that his phone bill somehow rose to the monthly 300 yuan. Only after inquiring did he know that the free broadband he had received had expired, but the service did not terminate, but he continued to deduct money.

　　For users who want to unsubscribe, change packages or "port number transfer", the process is relatively troublesome. Xiao Zhang, who studied at the Central Academy of Fine Arts, applied to the operator for changing the lower tariff package in early 2018, but it has not been changed successfully so far. "The salesman first said on the phone that he would help me change it and take effect the next month, but then I found that the previous package had been automatically renewed for one year. To cancel the contract, I can only go to the business hall where the number belongs. My mobile phone number is from my hometown in Henan. It is impossible to go back from Beijing just to change the package. "

　　"port number transfer" forced operators

　　Can consumers avoid the above troubles while enjoying the preferential treatment? During the interview, Xu Li, a staff member of China Unicom, suggested that consumers should fully understand the package and contract before buying. "In order to avoid unnecessary troubles, users must carefully read the terms of the package contract before or during the handling of such bundled packages, and ask for early termination, ‘ Port number transfer ’ , due fees, etc., and then make a choice based on your own situation. " Xu Li said.

　　In response to the problem of automatic fee deduction, Liu Chunyan, an associate professor at Tongji University Law School, pointed out that mobile phone operators and users signed service contracts. If the operator does not inform the user and changes from free to charge, it is a unilateral change of the contract, which is a violation of the contract and constitutes a breach of contract. Furthermore, taking the form of automatic deduction unilaterally also infringes on the property rights of users, which constitutes infringement.

　　The promotion of "port number transfer" is also forcing major operators to improve network quality and service level as soon as possible. On May 21st, at the policy briefing in the State Council, Chen Zhaoxiong, Vice Minister of the Ministry of Industry and Information Technology, pointed out that users should be guaranteed to fully enjoy the rights and interests of "port number transfer" and ensure that "port number transfer" will be realized nationwide before November 30th this year, so as to truly "take the number in hand and leave when you say it".

　　Xu Li believes that "port number transfer" has brought great challenges to operators. "In the future, we will optimize the package and simplify the products from the user’s point of view." Yan wang said with emotion: "‘ Port number transfer ’ The times are coming, and operators should think more about how to make good products. Users should be informed of the package terms more transparently, instead of using ‘ Free broadband ’ Wait for the gimmick to tie the user. "

Yang Mi Tang Yan Ma Su star issued a statement that it was him!

Star pop statement

1905 movie network news 　Seeing that the Spring Festival is approaching, the circle of friends is full of various ticketing links. The entertainment circle has never stopped, with stars or studios making statements every three days and frequently making headlines in hot search. However, after reading these statements, Xiaobian really wants to say, are you sure this is a statement, not widely publicized?

On January 15th, yang mi studio issued a statement. If it weren’t for this statement, who knew that there was such a netizen named Liu Kongqing who wrote articles such as "International Power Wars Gum" and "Tang Yan-Yang Mi Battle", describing Yang Mi and Tang Yan as plastic sisters. As a result, how many people want to search for articles to get a glimpse of it. (See for details)

Yang mi studio statement

Actually, Tang Yan, who is "not a plastic sister flower" with Yang Mi, also made a statement two days ago, but now the limelight is completely overshadowed by Yang Mi, who is "not a plastic sister flower" with her. On January 13th, Tang Yan’s studio issued a statement, aiming at Huang Yiqing’s suggestion that Masu took the two-character actress to "do her hair". But if it weren’t for this statement, we really didn’t associate this two-character actress with Miss Tang Yan. (See for details)

One step earlier than Miss Tang Yan, it is necessary to count "I didn’t bring her to do my hair.""Masu. On January 12th, Masu Studio issued a statement saying that it would sue Huang Yiqing for "libel". Therefore, before Huang Yiqing broke the news that Masu had cheated on her many times, fell in love with Daxun Wei, and often introduced the actress to "do her hair", which became well known. Support Masu to take legal measures, and don’t drop the lawsuit halfway! (See for details)

Masu studio statement

And even earlier than Masu is ZhangJike, who "has never done hair with her". In response to Huang Yiqing’s statement that athletes named Z had "done their hair" with Masu, on January 11th, ZhangJike Studio clarified that they were just "normal friends". As soon as this statement was issued, Huang Yiqing, who was originally called "Crystal’s ex-husband", was immediately upgraded to "the new entertainment circle discipline inspection commission", and his fans and popularity soared. (See for details)

ZhangJike studio statement

And the "initiator" of all this can be traced back to PGONE, the protagonist of the first entertainment news in the New Year. On January 5th, PGONE Studio issued a statement, saying that "the network rumored that PGONE junior high school students broke the news, which involved the act of raping a minor and making her pregnant and abandoning it", declaring it as "nothing, empty talk and rumors".Netizens have said that "PGONE Studio is crazy" and "I actually came up with such a trick in order to transfer the topic of derailment".(See for details)

PGONE studio statement

All in all, in a word, no one may have known about these messy news, but now when you make a statement, the whole world knows it. Are you sure that you are not making a statement to publicize it, or to discredit yourself? All right, as long as you’re happy.
