With the rapid change of information technology, in the education industry, intelligent hardware has gradually become the needs of schools and students. How to collect teaching data in real time and without any sense has become a consideration for students and teachers when selecting educational hardware. According to estimates from the Qianzhan Research Institute, the market size of emerging smart hardware categories in education intelligence (scanners, writing pens, smart work lights, etc.) in 2020 will be approximately 8.9 billion yuan.
Founded in 1999, Xuezhiyou takes "lattice technology coding + chip-level solutions" as its core business, relies on dot matrix technology to realize paper-pen interaction, and creates writing information solutions. To put it simply, what the dot matrix pen can achieve is "write on paper and read on the screen".
The specific presentation effect achieved is that when students use the dot matrix pen, the notes left on the teaching aid can be restored to the screen accordingly. And the handwriting, size, position, and the content of the page on the teaching aid can be synchronously copied to the screen position.
Dot matrix pen rendering effect
Xuezhiyou's dot matrix pen technology and product solutions include chips, lenses, encoding, decoding, coding and typesetting software, SDK and other technologies, involving a variety of technologies and process categories such as optics, chips, encoding, images, and printing.
To achieve this effect, two elements first need to be present. The first is the pen itself. The dot matrix pen is composed of a self-developed recognition algorithm chip, battery, camera module and replaceable refill, which can realize recognition while writing. And after the dot matrix pen is connected to the Internet, it can be used as an entrance for data collection to transmit the content to the electronic terminal. In terms of feel, the weight and sensitivity of the dot matrix pen are similar to those of a gel pen for writing.
The second is the dot matrix code printed on the teaching aid paper. The dot codes on the paper are equivalent to auxiliary coordinates. Through the recognition and decoding of the integrated chip of the camera and dot matrix recognition, the coordinates near the pen tip are obtained, and the handwriting coordinates can be calculated. And restore the original image on the electronic screen, retrieve the data content associated with the dot matrix code, and form a spatial corresponding relationship.
Xuezhiyou's core advantages have three aspects:
The first is self-developed decoding chips and encoding capacity. Different from externally purchased chips, self-developed chips integrate image capture, processing and dot matrix code analysis, which can improve decoding efficiency and recognition rate, reduce product power consumption, thereby reducing the cost of dot matrix pens.
In terms of encoding, Xuezhiyou uses variable array codes. In terms of encoding amount, the number is large enough to achieve non-reuse.
The second is the screen handwriting display effect. In traditional writing interactions, the pressure sensitivity and pen tip accuracy of the pen are important factors that affect the user experience, and also directly determine the display effect on the screen. In terms of pressure sensing, Xuezhiyou innovatively uses a combination of two types of pressure sensing technologies to improve pressure collection. In terms of presentation effect, the handwriting on the screen can show the thickness, sharpness, etc., and there is no jaggedness, dullness, or distortion after enlargement.
The third is the visual effect of paper printing. Currently, the paper printed with dot matrix codes on the market has an overall darker page color, a grayscale value above 10, and clear dot codes, which must have affected the visual effect. Bangbangbang's application of coding and printing technology can control the gray value of paper code points below 4, making the printed code more invisible and less different from ordinary paper.
Product display
Centering on dot matrix pens, paper-pen interactive peripheral products include pen refills, smart pen boxes, dot matrix notebooks, LCD writing tablets, smart blackboards, etc. Among them, there are three types of refills: gel pen, metal, and plastic, which can be selected according to the specific writing medium. In terms of market, Xuezhiyou is positioned as a dot matrix pen technology solution to help partners make in-depth applications in various industries.
At present, XUEZHIYOU's business is mainly in the field of education, and has established cooperative relationships with educational cloud platforms, publishing houses, private teaching aid publishers, and large printing plants. The first is the classroom application. When the dot matrix pen is embedded in the smart classroom scene, the teacher can directly call the students' practice handwriting on the smart whiteboard terminal for teacher-student interaction.
The advantage of this is that all student pages can be displayed on the terminal display. The second is the AI calligraphy practice application. When practicing calligraphy with hard pens and gel pens, the software can give scores, provide posture reminders, and call up video explanations of famous handwriting demonstrations. The second is the application of intelligent teaching aids, including primary and secondary school-based teaching aids, extracurricular teaching aids and public examination teaching aids. When students use teaching aids to study, teachers can make corrections on the remote terminal.
In addition, applications in cultural and creative, government affairs, medical, financial and other fields are also application scenarios where dot matrix pens will be deployed in the future. For example, government records signing and approval, meeting shorthand, production filling, illustration drawing, font library output, handwriting recognition ability output, etc.
In terms of team, most of the company's core members come from Huawei, China Telecom, Foxconn, ChinaSoft, etc., and have currently obtained more than 70 patents and software works. He has more than ten years of experience in smart home, educational electronics, publishing digitalization and educational information services, and has rich experience in invisible code point associated data solutions.
