Today is International Children's Day on June 1st, and I believe many parents have included many smart technology items in their gift lists for their children.

Nowadays, intelligent devices such as smartwatches, dictionaries, pens, and companion robots are emerging one after another, some of which can share parents' worries while others can assist children in their learning.

So, what are the principles of these technological products? How do they help parents and children? The reporter from Science and Technology Daily interviewed relevant experts on this matter.

Smart Watch:

Integrating positioning and health monitoring

Nowadays, most of the watches children wear are smart watches with a strong sense of technology. A smartwatch is a wearable device that combines the functions of a smartphone and a watch, with core functions such as location loss prevention, audio and video calls, as well as various functions such as electronic payment, health monitoring, social chat, photography, and intelligent object recognition.

For example, when encountering an emergency, parents can use the positioning function of their smartwatch to know their child's location; When two children wearing smartwatches want each other's contact information, they can add friends through the "touch" function

At present, smart watches are not only loved by children, but also provide parents with intelligent and convenient childcare tools. "Xiang Ligang, the chairman of the Zhongguancun Information Consumption Alliance, said that a related report states that in China, smart watches are quite popular among children aged 5 to 12, with one in every three children owning a smart watch.

Xiang Ligang introduced that from a hardware perspective, a smart watch has components such as a processor, memory, display screen, sensor, battery, wireless communication module, etc. These components are connected to each other through circuit boards to form the entire system. The software for smartwatches includes operating systems and applications.

So, how exactly does a smart watch achieve various functions?

Smart watches cover indoor and outdoor positioning functions, mainly based on three types of positioning technologies: GPS positioning, base station positioning, and WiFi positioning. "Yan Huaizhi, a member of the Information and Communication Technology Committee of the Ministry of Industry and Information Technology and director of the Institute of Network and Security at Beijing University of Technology, said that in particular, indoor and floor positioning is mainly achieved using base station positioning technology, combined with specific algorithms, and supplemented by massive data collection.

A reporter from Science and Technology Daily came to a shopping mall in Beijing to try out a smart watch. After using the watch to make a video call to a bound phone, the phone will display information such as the mall floor, surrounding stores, and watch status of the smart watch. It can also view the historical movement trajectory of the watch wearer.

In addition, Yan Huaizhi stated that smart watches can also utilize intelligent monitoring algorithms and highly sensitive sensors to monitor children's physical and motor status 24/7.

The sensor is located at the bottom of the smartwatch dial, which is tightly attached to the skin when worn. It can monitor various states of the watch, such as acceleration, gravity, position, direction, etc. Through the analysis and calculation of these data, children's movement data can be obtained. Yan Huaizhi added that in addition, the smartwatch can also collect biological data of the wearer at any time, such as heart rate, blood oxygen, blood pressure, non-invasive blood sugar, body temperature, respiration, etc By intelligently analyzing various physiological indicators such as sleep status, combined with corresponding apps, parents can grasp their child's physical health status.

Yan Huaizhi reminds children that when using smart watches in their daily lives, they should avoid falling, bumping, or being hit, and avoid coming into contact with solvents and liquids such as soap and water. Secondly, do not charge the smartwatch in a damp state. Once again, it is important to pay attention to the synchronization, matching, and upgrading of mobile apps and smartwatches.

When children use smart watches, they may become dependent, "Xiang Ligang reminds parents to remind their children not to operate smart watches during class; In addition, children should be advised to use the electronic payment function of their smartwatch with caution to avoid mistakenly using it as a game recharge.

Dictionary pen, translation pen:

Load a large dictionary into a pen

A small dictionary pen can hold a thick Chinese and English dictionary. Just like using a correction tape, gently scan the target content with a transparent wide "pen tip" to translate between Chinese and English, read sentences aloud, and even explain the scanned target content. Some dictionary pens also have a "vocabulary book" function, which can automatically store unfamiliar words that users do not know, and then import them into mobile apps for users to learn and remember.

The dictionary pen adopts infrared scanning technology, which first uses the camera component of the pen head to capture multiple images per second, then concatenates and corrects the small images, and then uses optical character recognition technology (OCR technology) for recognition, "explained Xiang Ligang.

There are many scenarios in daily life where OCR technology is used. For example, mobile apps scan business cards and ID cards, and identify the information within them; Cars entering parking lots and toll booths do not require manual registration and automatically recognize license plates.

Yan Huaizhi introduced that it has been more than ten years since the first domestically produced dictionary pen was introduced in 2011. In the future, there will be two main directions for the development of dictionary pens: one is to improve the speed and accuracy of text recognition, and the other is to enhance the accuracy of language translation, "he said.

It is understood that the new generation of dictionary pens not only have traditional optical text recognition functions, but also are equipped with laser assisted positioning cameras, which can achieve functions such as sharing, editing, and printing.

In addition to dictionaries and pens, there are also translation pens that are powerful tools for helping children learn foreign languages. The latter has made great efforts in translating between Chinese and English. Translation pens can not only explain the meaning of individual words, but also translate sentences and texts (both in textual and phonetic form), resulting in translation results that are closer to natural language. Some translation pens are also equipped with speakers and display screens, which can output translation results in real-time in the form of text or sound.

Xiang Ligang introduced that the translation pen consists of a scanning head, recognition engine, and translation software. On the basis of OCR technology, the translation pen can also utilize TTS translation technology, which is "text to speech" technology. With the support of built-in chips, the pen can intelligently convert text into natural speech streams through the design of neural networks and the training of artificial intelligence large models.

In addition, in order to prevent children from excessively relying on translation pens in foreign language learning, some translation pens have now added a "child lock" function. After this function is turned on, the translation pen will turn off the entire sentence translation function, preventing children from not thinking throughout the translation while doing homework, and developing a habit of excessive reliance on such tools.

Companion type robots:

Being both a "playmate" and a "tutor"

Companion robots can walk and move, known as the "talking encyclopedia", and can easily answer "100000 whys". They are also a robot "tutor" who can take children to learn Chinese, English, and programming.

The positioning of companion robots is companions. They are not children's teachers or parents, but rather their anthropomorphic 'companions'. Yan Huaizhi said that such robots can achieve companion functions through key technologies such as mechanical transmission, artificial intelligence, and facial recognition.

Yan Huaizhi stated that currently, with the support of rapidly changing artificial intelligence technology, companion robots are continuously improving their actions, language, and even providing emotional anthropomorphic expressions. In addition, the basic functions of this type of robot, such as facial recognition, human tracking, intelligent obstacle avoidance, automatic charging, temperature and humidity sensing, are also constantly being upgraded.

In terms of interaction, companion robots can achieve functions such as photography, storytelling, game interaction, voice interaction, picture book reading, content on-demand, and two-way video calls.

For example, placing a picture book in front of a robot can identify the cover and then read the book aloud as the user turns the page.

However, in Xiang Ligang's view, companion robots are still in their early stages and can only complete simple tasks such as playing with others, accompanying students, or Q&A communication. Overall, the cost-effectiveness of this product is not high, far from reaching the level of widespread adoption, and cannot meet more personalized needs.

In addition, Yan Huaizhi stated that long-term use of robots to accompany children carries potential risks.

No matter how advanced intelligent robots are, they can never replace the companionship of real humans, especially parents. Yan Huaizhi reminds that excessive use of similar products should be avoided, otherwise it may have a certain degree of negative impact on children's language, emotional, and interpersonal development.

Intelligent baby care device:

Protecting Children with Wireless Network Technology

In traditional baby care settings, caregivers need to constantly pay attention to whether the baby is crying, vomiting, being covered by clothing, falling out of bed... These issues constantly affect the caregiver's energy. With the shift towards scientific and refined parenting methods, intelligent baby care devices have emerged.

Many intelligent baby care devices have a cute appearance - they have a big head, which is actually an intelligent camera that can be placed in the baby's room to monitor the baby's face, breathing, crying, etc.

When they "detect" abnormalities, they will issue a timely warning, and caregivers can "see" every move of the baby even if they are unable to be by their side at all times.

Intelligent baby care devices are like parents' 'eyes and ears, "Yan Huaizhi said." Intelligent baby care devices are essentially a wireless home safety protection system, mainly composed of a care terminal and a display terminal. This caregiver utilizes wireless network technology to regularly scan and recognize baby expressions, movements, and other images. It also transmits the child's real-time dynamics in the form of video or audio to the caregiver's mobile phone through network digital signals. When it uses artificial intelligence technology to identify and evaluate a baby in a crying state, it will play soothing music to soothe it and send a warning to the caregiver's display.

It is worth mentioning that the intelligent baby care device has an electronic fence function, allowing users to set the child's range of activity, that is, to set a virtual electronic fence through ultrasonic radar. When the child's activity area exceeds this range, the caregiver will sound an alarm.

In addition, users can also set up a child care area, where some of the caregivers outside the area cannot be photographed, thereby effectively protecting personal privacy.

Of course, parents cannot treat smart baby care devices as "universal tools".

Yan Huaizhi reminded that the companionship of parents is irreplaceable by any intelligent product. In addition, manufacturers need to pay attention to privacy protection issues and take further measures in product functionality to better protect the privacy of infants and caregivers.
