Zhou Feng, CEO of NetEase Youdao, said: "Poor student learning habits, lack of concentration, and parents' inability to effectively tutor are the main dilemmas in family learning, and intelligent learning lights will become a product that solves real problems." ”
At present, there is a myopia rate of 35.6% among primary school students, 71.1% for junior high school students and 80.5% for high school students. Tao Yong, a joint research and development partner and ophthalmologist of Youdao Intelligent Learning Lamp, said that if the probability of myopia continues to increase, it will lead to a decline in the overall population quality in the future.

The Youdao AI team found that the table lamp that appears on the student's desk every day has a natural companion attribute, so they use the table lamp as a carrier to connect the learning needs of students at home, on the way to school, and in school, so that students can complete the efficient learning of the whole scene in the intelligent learning ecology.
Affected by the epidemic, Youdao's new product launch was held online, and R&D personnel, product managers and the first batch of users introduced the research and development process of intelligent learning lamps, functional integration and the AI technology behind them through different short videos at home.
Subsequently, Zhou Feng, CEO of NetEase Youdao, Wu Yinghui, head of NetEase Youdao intelligent hardware, and Lin Hui, an AI technology expert at Youdao, conducted in-depth exchanges with the media such as Zhidong to explore the unique functions behind Youdao intelligent learning lights, AI technology innovation, and product iteration trends.
1. Equipped with AI efficient three-step learning method, concentration and memory are increased by nearly 20%
Tao Yong participated in the research and development process of Youdao intelligent learning lamp, he said: "Long-term close use of the eye is the culprit of myopia, and inappropriate light is the accomplice." ”

Therefore, in response to the above two key factors, the R&D team of hundreds of people in Youdao has launched the first Youdao intelligent learning lamp after nearly two years. The smart learning lamp has a warm off-white appearance, and its light is inspired by a surgical-grade shadowless lamp, which travels through four layers to make the light softer.

Chen Chen, a senior teaching and research expert for ten years, said: "The three problems of no learning objectives, easy dispersion of energy, and lack of feedback mechanism are the main problems of students in the learning process."
Therefore, Youdao Intelligent Learning Lamp adopts the AI efficient three-step learning method.
Before studying, Youdao Intelligent Learning Lights can help students make reasonable plans and make effective use of time. In addition, parents can also connect with smart learning lights through mobile phones to help students make learning plans.
In the learning process, the learning lamp can also help students shield themselves from external interference and achieve independent and efficient learning. It is equipped with fingertip word search, sentence reading and other functions, of which, the fingertip word search response time is 0.5 seconds, sentence intensive reading function not only includes the Chinese interpretation of the sentence, but also includes idiom allusions, ancient poetry interpretation and other associative content.
At the same time, in order to meet the different learning habits of individuals, intelligent learning lights will also be equipped with different types of timing rules, sitting posture, concentration, and built-in multiple types of ambient sound effects.
▲Sentence intensive reading function
Wang Zequn, product manager of Youdao intelligent learning lamp, mentioned that after learning, intelligent learning lamp can intelligently classify and sort out the wrong questions for the students' difficulties in the learning process, and then connect to the printer to generate students' exclusive wrong question books.
Secondly, Chen Chen also mentioned that the Youdao intelligent learning lamp is equipped with a number of authoritative language learning dictionaries such as Youdao self-developed dictionary, Xinhua dictionary, collins English-Chinese double interpretation dictionary, etc. It is worth mentioning that the xinhua dictionary's standardized stroke order animation and standard pronunciation are also presented in it.
In order to test the actual effect of intelligent learning lights, Youdao and Lin Sisi, a doctor of cognitive neuroscience from the Chinese Academy of Sciences and an expert of the New Zhiyuan Artificial Intelligence Think Tank, conducted a neurological user experience test, which included 32 students in grades one to six.
The results showed that compared with the traditional table lamp, the Youdao intelligent learning lamp increased the students' concentration by 17.21%, the memory by 18.73%, and when learning Chinese, the students' memory increased by nearly 30%. Lin Sisi said: "This is a significant improvement in the neurological test process. ”

Second, adaptive light algorithm + full spectrum low blue light, intelligent recognition of learning light
Tao Yong said that at present, the myopia rate and high number of people in the mainland from primary schools to universities have further increased, and myopia will further enhance the hidden dangers of blindness and blindness in the future.
Therefore, the intelligent learning lamp starts from the two angles of long-term close-up use of eyes and inappropriate light, relying on the technical advantages of Youdao, forming two cores, namely full-spectrum low blue light technology and adaptive light algorithm.
▲Intelligent identification light system
For the full-spectrum low-blue light technology, Tao Yong also mentioned that the full spectrum refers to the light as far as possible to simulate the natural ambient light illumination, and the low blue light refers to the removal of harmful light from the sunlight as much as possible. Among them, 400-450nm of short-wave blue light is harmful to the human body, and students continue to be exposed to short-wave blue light for two hours, which will cause damage to the retina.
Wang Zequn said that the learning lamp uses a full-spectrum lamp bead that is 3 times higher than the cost of ordinary lighting, and its microprism light contains 170,000 microcrystalline particles, making the light softer.
In addition, the dual-chip technology will further enhance the long-wave blue light effect that is beneficial to the learning process, Tao Yong said: "Long-wave blue light can inhibit the production of melatonin and improve students' learning concentration." ”
Traditional lighting is often fixed parameter configuration, generally need manual adjustment, lack of scientific light guidance, its light will not be automatically adjusted to the light of the environment. At the same time, the difference in desktop materials, ambient light, and everyone's psychological feelings about brightness will make users feel differently.
Therefore, Youdao intelligent learning lamp links lighting, desktop and user feelings, etc., equipped with Smart Light intelligent eye protection, which can intelligently identify students' learning environment and intelligently match the appropriate light.
In order to protect students' eyes, the learning lights are also equipped with healthy eye reminders and eye protection exercises, which intelligently remind students to protect their eyes according to the "20-20-20" principle, that is, use their eyes for 20 minutes at close range and look at grass, green trees or other objects 20 feet away for 20 seconds.
Third, the local calculation amount is only 3T, and the recognition accuracy rate exceeds 99%
Lin Hui said: "The core of Youdao Intelligent Learning Lamp lies in the 'intelligent brain', which is its powerful desktop learning analysis engine. ”

This desktop learning analysis engine can analyze students' behavior under the lamp and learning, such as the position of the book, hand, and pen placement, the position of the topic, the teacher's annotations, the subject to which the topic belongs, as well as the position of the pen tip, the order of strokes, etc., and finally rely on Youdao deep learning neural network technology to achieve fast and accurate positioning, recognition, and judgment.
Under normal circumstances, the intelligent recognition of Youdao learning lamp, fingertip word search and other functions will produce a large amount of data, and these huge amounts of data can not be quickly processed locally, and need to be computed on the cloud server, which further increases the time of identification and search. Therefore, in order to achieve "fast" and reduce the calculation delay, Youdao's R&D team put user-related content into the table lamp for local calculation, and reduced the 300T computing amount to 3T.
Secondly, the learning lamp is also equipped with a neural network processor, and its operating speed has reached ten times that of ordinary CPUs.
Moreover, when students use the fingertip word lookup function, the recognition process will not be affected by the text direction, typography direction, irregular fonts, etc., and the recognition response speed is within 500 milliseconds, while the average response time of the industry is more than 1.5 seconds.
In terms of accuracy, the learning lamp can achieve accurate positioning, judgment and recognition, which relies on the accumulation of Youdao in the education scene for many years, and the accuracy rate of positioning and judgment can reach more than 98%, and in terms of recognition, relying on the recognition technology of Youdao dictionary pen, its recognition accuracy can reach more than 99%.
Lin Hui also said that in the actual use process, students may be tilted during the photo process, or there are a large number of scrambled notes in books, and the desktop learning analysis engine will automatically erase handwritten notes, making the recognition more accurate.
In the future, this powerful desktop learning analysis engine will be in-depth exploration in the fields of algorithm model to cognitive psychology, Lin Hui told Zhidong that experiments have proved that small actions of students in the learning process may help improve learning efficiency, and in the future, youdao AI team will also put this experimental result into the learning lamp through functional updates and other forms.
Zhou Feng stressed in the exchange with Zhidong that updating through OTA (aerial download technology) is what Youdao has always insisted on, and in the future, Youdao intelligent learning lamp, Youdao dictionary and other products will continue the traditional OTA update, and ensure that Youdao intelligent learning lamp has a long life cycle.
Conclusion: In the smart education market, data privacy protection is the key
Education is the topic of concern in the whole society, Youdao has many years of experience in the field of education hardware such as Youdao translation eggs, Youdao dictionary pens, etc. This time, the use of AI technology makes the intelligent learning lamp in the health of the eyes and light regulation, can intelligently identify the learning environment and learning process of students, and use AI to create intelligent education hardware throughout the learning process.
Under the influence of the epidemic, students' time to learn at home has increased, and smart education hardware has taken on the heavy responsibility of learning at home. In recent years, different types of eye lamp release, OPPLE, vigorous and many other manufacturers of learning lights, eye care lamp products have landed, Youdao also began to rely on its AI technology to enter this market segment, but the blessing of intelligent identification function will also make users worry about children's personal privacy, data security, therefore, how to further ensure data security on the basis of technological updates, is the intelligent education hardware field should continue to pay attention to the problem.
