Dot matrix pen = monitoring pen? Understand the main application scenarios of the dot matrix pen in one article.
"Dot matrix pen" was pushed to the focus of public opinion because of this wave of news. Many people equate the "dot matrix pen" with the smart pen for smart education, or even with the "supervisory pen" and "monitoring pen". In my opinion, such an evaluation is inevitably somewhat one-sided and distorted. So, what other application scenarios does the "dot matrix pen" have?
It is understood that the main application scenarios of "dot matrix pen" on the market are as follows:
1. Paper and pen interactive smart classroom scene
Many schools promote the deep integration of information technology and curriculum teaching, pilot smart classrooms, and adopt tablet-based smart teaching solutions. However, long-term use of tablet computers will damage children's eyesight and easily lead to dependence on electronic products.
Using a dot-matrix pen instead of a tablet for interaction can retain students' traditional writing habits on paper, and at the same time collect teaching data in real time and without feeling. For example: when students use dot matrix pens, the notes left on the teaching aids can be restored to the screen accordingly. And the handwriting, size, position, and the content of the page on the teaching aids can be reproduced on the screen position synchronously. Through Bluetooth or WIFI, students' answers or notes can be accurately transmitted to the teacher's end in real time.
Then, the teacher asks questions in the classroom, and the students answer on paper. The students' correct rate, time to complete the question, and completion rate are clear at a glance, which improves classroom efficiency. At the same time, teachers can implement targeted teaching according to each student's answering process to improve personalized teaching.
At present, many schools across the country are using such dot matrix pens in smart classrooms. Judging from the official websites of various dot matrix pen manufacturers, smart classrooms are one of the important application scenarios.
2. Calligraphy teaching scene
In traditional calligraphy teaching classrooms, teachers usually only pay attention to students' writing results, and lack of evaluation and tracking of students' writing process. Most of the Chinese character learning systems based on animation demonstrations only focus on the practice of stroke order. "Strokes" are not the original handwriting of students, which cannot promote personalized learning and evaluation.
The "dot matrix pen" application solution is applied to the scene of calligraphy practice. With the help of technologies such as dot matrix recognition, handwriting recognition, learning analysis and machine learning, handwriting extraction and handwritten Chinese character recognition are realized, and the interaction between teachers and students is supported by an intelligent teaching system. teaching. That is, dot matrix codes are laid on the basis of traditional copybooks, and AI scoring is performed through the traces written by dot matrix pens, telling users whether the strokes of the written words are correct and whether the writing is neat. On the basis of not changing students' traditional writing habits, teachers can simultaneously monitor the writing process of all students, and arbitrarily retrieve the writing works of one or more students for various forms of case explanation.
3. Note-taking scene
Almost everyone in modern society has a computer, but many people are still accustomed to using paper and pen to take work notes or meeting minutes. However, ordinary paper and pen records have the pain point of "incomplete memorization, inability to find, and easy loss". For example, if the notebook is lost, all the contents of the notes are also lost; if you want to find a certain meeting record, you may not be able to find it even if you search the entire notebook.
Dot matrix pen + notebook with dot matrix code can solve these problems better.
Support OCR recognition. Most dot matrix pens also support OCR recognition for written content, not only for text recognition, but also for formula recognition.
Support deep search. All content inserted into the note-taking app through the dot-matrix pen, such as pictures, documents, and text content in them, can be indexed and searched.
Dot matrix pens are very suitable for office workers and students who have the habit of handwriting and view handwritten notes anytime and anywhere.
Dot matrix pens are also very suitable for designers who have handwriting drawing, graffiti, and creative habits.
