Researchers collected three hundred Data of school aged myopic children according to Divided into three groups (less than three hundred Degree; three hundred degree ~600 Degree; six hundred Above), each group one hundred People, respectively record the writing posture, and then conduct statistical analysis. Results found three hundred Among the children, the ones with correct writing posture (the thumb does not touch the index finger) are thirty-seven Person twelve point three ％； Incorrect writing posture (thumb touching index finger or thumb crossing index finger): two hundred and sixty-three Name eighty-seven point five ％。 Moreover, with the increase of incorrect writing posture, the diopter is also deepening. Researchers believe that when children sit upright, if the thumb holding the pen touches or crosses with the index finger, the finger will block the line of sight, and children cannot see the tip of the pen clearly, forcing the head to tilt to the left, which shortens the distance between the eyes and books, increases the incidence of myopia, and speeds up the development of myopia. It can be seen that the pen holding posture has a great relationship with the incidence of myopia. Ministry of Health Director of key laboratory Professor and doctoral advisor said that the laboratory had recently conducted a survey on myopia teenagers, and found that the biggest cause of myopia was not the traditional view that the eyes were too close to the book, but the wrong gesture of holding the pen. BPOO The anti myopia intelligent pen is an intelligent writing pen that can comprehensively prevent myopia in children's learning and life. The four major factors (pen holding posture, writing and sitting posture, ambient light, and operation duration) that affect the visual health of teenagers in the writing process are comprehensively monitored and compulsorily corrected, so that teenagers can naturally develop good habits in the writing process and grow up healthily. First of all, thank the players one hundred This trial was provided. After receiving the product, my daughter liked it very much. After taking it to the class, the students liked it very much. Since children like it very much, it must have a high face value. Let me enjoy this magical smart pen first Unpacking The packaging box is made of kraft paper, which tastes like millet packaging. The box cover is a product LOGO One side is the company's website, which is not very distinct from the color contrast of the box. It can be seen clearly only when the light is good. At the bottom of the box are the product parameters, the company's website and telephone. The rest are free of any patterns and words, which are not cumbersome and cumbersome, giving a simple and generous feeling.
Open the box cover, and the high-end smart pen lies quietly inside. In order to take out the pen conveniently, the middle part is dug out, which makes it easier to take out the pen. The smart pen is uniformly white and polished. It was discovered after taking it out that it was not white, The material is polycarbonate, which has good impact resistance, thermal distortion resistance and high hardness.
The pen has a hardware part inside, which is slightly larger than the ordinary pen, but it does not affect writing through use.
The following details the names of various external parts. By getting familiar with the names, you can almost use them. The top is the power switch of the pen, but not only the power switch, but also the usage settings of the pen. The charging interface is under the switch, and the interface specification is the same as that of ordinary Android phones, which means that it can be used in common with the phone charging line, and it will be much more convenient in the use process. Monitoring area and OLED The display screen will display some information after power on. The specific contents are described in the usage section below. Then there are indicator lights and small speakers. The small speakers that children need to correct will be reported, and the indicator lights will also have light reminders. When writing normally, it emits blue light. When the writing status is incorrect, The indicator lights up red. YBPOO The anti myopia intelligent pen is designed with a unique triangle grip area and anti grip angle, which is ergonomic. The details from the pen tip to the sensor are three Inside is the best pen holding distance, which can help children quickly grasp the pen holding posture. Of course, the bottom is the pen tip, which can be pen, neutral pen (including ball point pen) and pencil. (I used to call them three, but they are actually four)
There are still a lot of accessories. There are four small boxes. There are instructions, short cap, cap changer, charging line, automatic core out head, lead core, neutral pen core and ball pen core. Short tail cap and pen cap changer. Charging power cable. Automatic core pulling head and lead core. Neutral pen and ball point pen. Let's have a family photo.
Usage process First, let's talk about the preparations for use, BPOO The charging speed of the anti myopia smart pen is about one hour, and it can be used after full charge 5-7 Hours, for ordinary primary school students, can meet the writing of a day. The charging interface is the same as that of Android phones, which is convenient. However, it needs to be recharged once a day. I still hope the battery life can be improved. BPOO The anti myopia smart pen provides four types of refills. In fact, I think it should be classified into three types: pen, neutral pen, ball point pen and pencil. The installation and shape of neutral pen and ball point pen are basically the same. It is said in the instruction manual that when the pen head is unscrewed, as long as it is kept straight for a few seconds, the pen core will automatically extend. Through the actual test, the pen core automatically extends irregularly, sometimes it does not extend even after a long wait, even if it extends, it will quickly retract, but it is not difficult to pull it out manually. You can also continue to hold the pen correctly and unscrew the pen head. At this time, the pen core is extended, so you can directly replace the pen core. BPOO When the anti myopia smart pen is turned on or in standby mode, the pen tip extends when it meets the writing status, and it can write normally. When it does not meet the writing status, the pen tip retracts and gives a prompt, and the writing status is adjusted to continue writing. For which cases belong to the writing state, it mainly includes the angle of closing the desk, the distance from the eyes to the book, the duration of use, and the ambient light intensity, depending on the combination BPOO The anti myopia smart pen provides five Stages. It can be selected flexibly according to the specific situation of the child. What needs to be explained here is "delayed extension", that is, light and voice prompts will be given when incorrect status is detected three The pen core shrinks after seconds. If the writing status is corrected during this period, you can continue writing. Of course, the free mode can also be selected, in which the opening and closing of angle, distance and time detection can be combined at will. The angle, distance, light and time parameters can also be set by yourself, but the four parameters are also preset, and each parameter has three choices. For the above settings, it is required to use a long tail cap Turn over, confirm and return functions of switch on, function setting, Through actual experience, the settings are really not very convenient and difficult to control The four-dimensional direction keys sometimes make mistakes when setting, and turn to return when confirming key points. This should also be caused by the concentration of key areas. The voice and light of the reminder mode can be turned on and off. For use in the classroom, in order not to affect other children, it is recommended to turn on the light and turn off the voice. Voice and light can be turned on and off. My child uses three In the stage, the angle, distance and light intensity were tested. Angle: When the pen holding angle is not correct, BPOO The anti myopia intelligent pen sends out voice prompt if the pen body angle is too low, and if the pen body angle is too low, turn up the voice prompt , the indicator lights up red, and the refill retracts automatically. Distance: When the sitting posture is incorrect, it will send out the voice prompt of incorrect sitting posture, please adjust the voice prompt, the indicator light will send out red light to remind, and the refill will automatically retract. Light: When the environment light is too dark or too bright, The voice prompt "Please turn on the light when the light is too dark or please adjust when the light is too bright" will be sent out. The indicator light will send a red light warning, and the refill will automatically retract. Conclusions and suggestions BPOO The anti myopia intelligent pen body is beautiful and fashionable, which is loved by children. In use, it can correct children's wrong body posture, pen holding posture, and pay attention to the light brightness of the learning environment. The continuous writing time of children is also monitored, which can be said to be a sharp tool to protect children's eyes from myopia, with great practical value. After one week's use, the child's sitting posture and pen holding posture have been significantly improved, BPOO The intelligent voice prompt and flashing red light for myopia prevention have gradually decreased. I think if I persist in using them, I can completely correct the children's bad sitting posture and pen holding posture. However, in the process of use, we also found some shortcomings, and put forward several suggestions according to the actual situation. one It is difficult to set the pen. I know how to set it according to the instructions, but it is difficult to control what is up and down in the operation process, which is related to factors such as the pen cannot be set too large. Suggest APP , the setting function can be bound to the parents' mobile phones, and can also transfer the specific time period of children's learning, which is convenient for setting, and also conducive to parents' understanding of children's learning at any time; 2. In the north, especially in the northwest, the climate is dry. When using pens, because there is no pen cap, it is easy to make writing difficult, or even no ink, because of dryness. We hope to set a small and beautiful pen cap to prevent the inability to write due to dryness; 3. The inner liner of the pen is too small, and one ink is not enough for students to use in a day. I hope to increase the inner liner; 4. The battery has a short battery life. By using it, it will be charged almost once a day. I hope to improve the battery life by saving electricity or increasing the battery capacity. [Kunlun edited the post at 14:59 on June 22, 2015] |
