BEIJING, Beijing, November 4 (Wu Tao) The annual "double 11" is a shopping festival for consumers and a competition for e-commerce technology marketing strength. A number of novelty items will emerge. What "black technologies" will double 11 bring us this year? Zhongxin. com has combed this.

　　On April 4, 2017, many ancient and modern cultural celebrities "appeared" at the China Millennium Monument by means of holographic projection technology. Photo courtesy of China Millennium Monument

　　Magic holographic projection

　　It is reported that during Tmall’s "double 11", five large containers will appear in the landmark location of China’s first tier cities, and space scenes with different themes will be built inside the containers, and the outdoor holographic projection show will be used for the first time — — There will be 5-6 different life scenes on the facade of the container, which will bring unparalleled visual experience and the impact of a brand-new lifestyle to the citizens.

　　The so-called holographic projection, also known as virtual imaging technology, is a technology that records and reproduces the real three-dimensional image of an object by using the principles of interference and diffraction. Holographic projection technology can not only produce three-dimensional illusion in the air, but also make the illusion interact with the performers to complete the performance together, resulting in shocking performance effects.

　　"Eye-catching" shopping card

　　During the "double 11" period, a smart shopping sign with "insight" appeared in the convenience store in JD.COM, which was put into operation. After you walked over, "the snacks you like are new, and the favorite drinks are on sale". In short, what appears is either what you need or what you like, and it has achieved thousands of people, and different people have different effects.

　　It is understood that this "billboard" has done a lot of homework in advance — — The user’s gender, age and other information are sensed through the camera, and the preferences of consumers are found out by combining with the big data of JD.COM consumption information, and then recommendations are made according to preferences.

　　AR fitting is more normal.

　　Presumably, everyone is familiar with the original AR (Augmented Reality Technology) grabbing red envelopes, and this year’s "double 11", AR games and AR trials will be more normal. According to foreign media reports, it is estimated that tens of millions of people will participate in China’s "double 11" through AR fitting every year. In addition, the reporter noted that this year AR perspective technology will also join the "double 11" queue.

　　What is AR perspective? According to Tmall’s example, take a photo of a certain sofa and receive the goods into your mobile phone. When you get home, hold your mobile phone to the area where your sofa wants to be laid out. Through the projection of the screen, you can see whether the sofa is placed in this area, whether its style is the same as you want, and whether its size is appropriate. If it is suitable, you can buy it directly.

　　You can also recognize cars by taking pictures.

　　Lexus is recognized as Chery, Honda as Hyundai, and Cadillac as Emgrand. It is really difficult for car white to accurately identify the brand of the car. This year’s "double 11", Easy Car launched an activity with its "AI car recognition" function. Users can take photos of cars at will, and after uploading photos of cars from any angle, they can accurately match and analyze the specific car brands and models.

　　During the "double 11" period, users will also get a red envelope when they scan the logo, which will help users to identify the car models quickly and accurately, create more diversified car buying scenes, and also help car manufacturers to realize innovative marketing with cross-scene, multi-platform and zero distance.

　　"unmanned" technology popularizes logistics chain

　　This year’s "double 11", there are also many unmanned technology series. JD.COM has launched a number of products in one breath, including unmanned warehouses, unmanned trucks, unmanned supermarkets, unmanned convenience stores and intelligent supply chain open platforms.

　　It is worth mentioning that JD.COM unmanned warehouse "double 11" will be put into use in Shanghai. The whole process of unmanned warehouse has realized the whole process from warehousing, storage, packaging and sorting, and the whole system is intelligent and unmanned, with the ability to handle 200 thousand orders a day. Suning also said that its robot warehouse group has been officially built in Fengxian, Shanghai, covering an area of more than 200,000 square meters, and it is basically operated by unmanned warehouses.

　　"AI application, semi-artificial intelligence for traffic monitoring"

　　Wang Xiaozhong, Senior Director of R&D of JD.COM Mall, said that the biggest difference of JD.COM double 11 this year is the application of AI technology.

　　Core reading

　　How can online games prevent addiction and be effective and long-lasting? Experts suggest that parents should not instill in their children the idea that playing games is a sin, but should help them improve their self-control. In addition to setting up functions such as "one-click no play" and "limited consumption", game companies should also make plans to keep young people away from bad content. Only when the society gives guidance, parents teach by example, game companies develop high-quality content, and relevant departments assume regulatory responsibilities can a complete and effective closed loop be formed.

　　Games are charming and children are easy to indulge. How should parents, society and game companies treat and treat games? What measures can all parties take to prevent teenagers from indulging in online games? We interviewed game companies, relevant scholars and experts to discuss the solutions to game addiction.

　　How to guide children to play online games without affecting parent-child relationship?

　　Q: What are the characteristics of teenagers using the Internet? Why is there an addiction to online games?

　　Zhang Haibo, director of china national youth palace association Children’s Media Literacy Education Research Center: Today’s teenagers are aborigines in the digital age, and playing online games is their basic entertainment.

　　From 5 to 14 years old, teenagers have a "triple jump" rule in the process of contacting the internet: around 5 years old, they haven’t gone to school yet, but they may have contacted the internet, and online games have become a part of life; Around the age of 10, teenagers will not only search through the internet, but also participate in social activities and express themselves; Around the age of 14, the internet has become an inseparable tool in life, and some teenagers have even surpassed their parents in "network digitalization ability".

　　Teenagers are addicted to online games, often because there are four kinds of problems in parent-child relationship: first, they don’t understand, that is, parents don’t know what their children are doing online; The second is "poor relationship", that is, parents have not established a good parent-child relationship with their children online and offline; The third is "lack of guidance", that is, parents let their children play online games; The fourth is "bad demonstration", that is, parents themselves are addicted.

　　Q: What are the parents’ responses to children playing online games? What is the correct way?

　　Zhang Haibo: There are two common scenes in modern families: one is "network battle", in which parents control the network and never let their children touch online games; The second is "electronic nanny", which directly throws mobile phones and networks to children. In fact, excessive control and indulgence are not real education, and they are easy to aggravate teenagers’ addiction to online games.

　　Li Tao, producer of Zeno technology games: I know a parent who severely taught his son to play games, which made him nervous when he heard the word "game", but when others were playing, the child still couldn’t help peeking.

　　In my opinion, parents should not instill in their children the idea that playing games is evil. Too rigid management will make teenagers more inclined to decompress through online games. Parents should help their children to choose suitable games and establish their children’s aesthetic appreciation of high-quality online games. To help children choose high-quality games, we can first pay attention to the game age grading standards, secondly, we can simply try them out by parents themselves, and then refer to the evaluation and recommendation of the media and netizens. Only by knowing ourselves and ourselves can we grasp the initiative.

　　Liu Mengfei, lecturer of "Game Research and Gamification Practice" course in Beijing Normal University: Game is essentially a meaning system guided by rules.

　　Echo Gao, Ph.D. in Education, Psychology and Art History, University of Munich: Parents should do the following when dealing with online games: First, establish clear rules. Parents must know what their children are playing, and know where to play, when to play and how long to play. Second, to be a role model for children, parents can’t be addicts themselves. Third, provide children with opportunities to connect with real life. Psychology believes that the sense of reality is an important criterion to measure whether the psychological state is healthy or not. Some parents abroad spontaneously organize various sports associations, and parents take turns to take charge of classes. This practice not only creates opportunities for parents to accompany their children, but also provides them with real social circles. At present, many parents in China learn from it, such as organizing children to climb mountains and have an outing. Fourth, parents should accompany their children with high quality. High quality requires high attention and response, but not too much interference with children, giving them full freedom and maintaining good communication with them.

　　Ask the online game producer how to control the supply side?

　　Q: In game design, what responsibilities should game companies take to avoid adverse effects on teenagers?

　　Liu Mengfei: In the early stage of game development, game companies should care for young players and consider the needs of young people from the perspectives of vision, culture and experience. In addition, we should make relevant plans for young players, such as how to keep young people away from bad players, bad language and thoughts.

　　The game content can also be guided by some rules. If the player has pornographic and bullying performance, the game mechanism should be severely punished. When young players socialize properly and complete cooperation, they can be rewarded in terms of game values; On the other hand, if there is bad behavior in the game, players can be "sent" to a specific space to limit their freedom of play. To return to the normal space, we need to learn community norms and pass the answer test.

　　To guide gamers, we should use the rules and mechanisms of the game itself, try our best to respect the players’ discourse system and subjective initiative, and avoid overbearing paternalism.

　　Q: What measures can game companies take to prevent teenagers from indulging in online games?

　　Joe Cheng, Director of Tencent’s Growth Guard Platform: In early 2017, Tencent launched a growth guard platform, through which parents can bind their children’s game accounts, and conduct operations such as inquiry, reminder, time slot setting, one-click play ban and limited consumption. As of July this year, about 8.78 million accounts were bound to the growth guardian platform.

　　The growth guardian platform is divided into two modes: the super parent mode was launched in 2017, and its essence is the control tool for supervision and inspection; We will launch the Weteam model this year, on the one hand, urging parents to set an example, on the other hand, urging children to fulfill their agreements and get incentives. It is hoped that this model can cultivate the parent-child relationship of mutual trust, positive encouragement and entertaining.

　　In order to prevent teenagers from irrational consumption in online games, Tencent has launched a game consumption reminder function for minors. If the accumulated consumption of users reaches 300 yuan in the past 30 days, Tencent will remind the payment account owner.

　　At present, Tencent has cooperated with Peking University Institute of Education, Central Academy of Fine Arts, Virginia Institute of Functional Games, China Association for Science and Technology and other domestic and foreign academic and scientific research institutions to explore ways to enrich the educational model by using online games and build a healthy, positive, safe and reliable online game space for teenagers.

　　How to better control online games under the principle of seeking advantages and avoiding disadvantages?

　　Q: Many parents know about internet addiction rehabilitation institutions, and some even send their children there. Are such institutions reliable?

　　Liu Mengfei: The professional qualifications of many internet addiction institutions are rather suspicious. Although game addiction is listed as mental illness in the latest edition of the International Classification of Diseases released by the World Health Organization. But this does not mean that those institutions that quit Internet addiction are "innate" with legitimacy. Even for the definition of "Internet addiction", the standards of these internet addiction institutions may not be consistent and authoritative enough.

　　Some cases show that sending children to some internet addiction rehabilitation institutions will cause permanent damage to the parent-child relationship. After the children return home, their trust in their parents will be greatly reduced, and the parent-child relationship may become very indifferent or even tense.

　　Q: How to look at and do online games in order to prevent and control addiction for a long time?

　　Zhang Haibo: With regard to the network, we should adhere to the concept of "pursuing advantages and avoiding disadvantages": we can neither regard the network as a scourge nor leave risks unchecked. Parents should make the Internet "work for me" through active guidance, making it a good helper for entertainment, study and daily life, and a way to express themselves and participate in social activities.

　　Liu Mengfei: There are already hundreds of millions of gamers in China. Since the scale of players has reached such an order of magnitude, it is necessary to fully investigate and understand the actual situation before finding a targeted solution when solving related problems.

　　For online games, parents, schools and society can’t just see its possible negative effects. Only when schools give guidance, parents teach by example, game companies develop high-quality content and anti-addiction mechanisms, and relevant departments undertake the responsibility of formulating rules and supervision can a complete and effective closed loop be formed.

A running friend asked Lao Wang: middle-aged women, running is not to lose weight, just want to exercise.Running a few kilometers every day can achieve the effect of exercise.?

When a person is still in the novice period of running, he wants to give up at any time. When I entered the love period with running, I can already feel the fun of running, and my ability has been greatly improved. I want to run every day, and distance is a belief.

After running for a long time, I have reached the rational period, and I have a better understanding of the importance of healthy running, instead of blindly pursuing the amount of running, and I have a clear understanding and goal of my running plan.

Therefore, runners who can ask this question are generally mature runners.

However, there is no uniform standard answer to how much distance to run to achieve the effect of exercise.

Just like a pony crossing a river, the squirrel thinks the river is too deep, but the cow thinks the water is too shallow. Only by practicing can we find out the answer.

Some people run 10 kilometers every day to stay awake, but if you feel tired after running 10 kilometers every day, you need to make a change, because it is not suitable for you.

Let’s just say yesvary from person to person.

If you want to lose weight, you need to run more. Generally speaking, running for 10 kilometers or an hour at a time will have a better weight loss effect.

If you want to run a marathon, you need to run more: more than 10 kilometers each time, and pull a long distance of more than 20-30 kilometers every week.

For people who want to stay healthy, running 5-6 kilometers at a time is enough for about half an hour, which is more suitable for most people.

1. Moderate distance:Running about 5 kilometers is suitable for most people. According to personal physique and physical condition, it can be adjusted up and down appropriately to achieve the purpose of exercise without excessive fatigue. After exercise, it does not affect normal work and study. After a long time, most people can stick to it.

2, the time is moderate:Running for about 5 kilometers takes about 30-40 minutes, plus warm-up, stretching and relaxation, and the total time is basically about 1 hour. If you have the habit of getting up early to exercise, time should not be too tight.

3, moderate strength:Although running is a good way to exercise, it does not mean that the more you run, the better. From the point of view of health, running is not a competition or competition. What is important is to achieve the purpose of exercise, sweat and feel relaxed and comfortable.

When running, you should control your heart rate and keep it between 60% and 80% of the maximum heart rate, which is the best effect. If you run too slowly, you can’t achieve the exercise effect. If you run too fast, you will get tired easily and the time will be too short. Generally speaking, it is advisable to speak at a speed while running, so that the body feels relaxed and comfortable and will not feel tired.

In addition, we should pay attention to keep enough sleep and rest, exercise 4-5 times a week and rest for 2-3 days.

To achieve the effect of physical exercise, the key is to keep running instead of just paying attention to the distance of running.Perseverance and perseverance are important qualities needed for running and exercising.

Running is a long-term continuous exercise activity, and occasional running can’t effectively improve your health. The real effect comes from persistent running.

When we insist on running, our bodies will gradually adapt to this sport and get more benefits. Gradually increasing the running time and intensity can gradually improve our physical fitness level. Although we may feel difficult and tired at first, through perseverance, our bodies will gradually adapt and become stronger.

It is also important to keep a positive attitude. Running is not always easy and enjoyable, and sometimes there will be setbacks and difficulties. However, it is in overcoming these difficulties and challenges that our perseverance and determination are tempered and strengthened.

To achieve the effect of exercising,Perseverance is the key. No matter how many kilometers we run or how much time we spend, as long as we persevere, we will certainly be able to get good health and good sports results.
