Wisdom writing
Writing is a wonderful experience. Writing on paper always has a charm. Even in the information age, we always have a desire to keep handwritten notes. Especially in terms of smart education, when black technologies such as electromagnetic writing recognition, infrared dot matrix recognition, and ultrasonic recognition are integrated into writing, there will be a variety of smart writing pens.
Here we must first define and distinguish the concept of "smart pen".
The "smart pen" we are talking about today refers to smart pen products that can write on paper and pen through various recognition technologies. It has the function of connecting to computers, mobile phones and other devices for writing, and also has the function of independent record storage, and most of them use ordinary paper and general refills;

This type of product is also different from notebook products such as Elfinbook smart notebooks or Evernote smart notebooks, which require special recording paper and use mobile app image recognition, which have an independent writing recognition hardware system.

At present, the main "smart pens" are divided into two categories: electromagnetic induction recognition (EMR) and infrared induction recognition (IR).
Electromagnetic induction identification
Electromagnetic induction recognition is divided into active (active) and passive (passive) induction, but the basic principle is to locate the handwriting coordinates by cutting the magnetic field lines emitted by the electromagnetic board through the inner coil of the electromagnetic pen to achieve accurate, fast, and delay-free writing experience. The main difference is that the active electromagnetic induction uses the pen as the emission source, while the passive electromagnetic induction uses the writing board as the emission source. For the needs of ordinary calligraphy and painting, both can reach the induction effect of 2048 levels, but the passive electromagnetic induction has a higher precision level. The induction effect is better.
The old man of electromagnetic induction writing technology is naturally Wacom. As early as 2015, it withdrew from the bamboo spark writing series (belonging to passive electromagnetic induction) to the consumer market.
Moleskine smart pen
Moleskine's product is a smart pen set highly recommended by many Wenqing. The price of nearly 2K is also very high. It also uses a dot matrix infrared solution, but the price is far more expensive than the previous two similar products. The app is really easy to use, which is worthy of the word"legendary".

Different from the writing principle of electromagnetic induction, infrared dot-matrix induction needs to be written with special paper using dot-matrix technology (that is, there are dense dot-matrix on the paper to facilitate multi-dimensional space positioning of infrared cameras), so this type of smart pen cannot be used in Write on plain paper. At the same time, the level of infrared dot matrix technology is uneven, especially in hardware equipment, because the high-speed infrared design heads and ISP image processors of various companies are different, and the performance gap is also very large. Due to the different built-in battery capacity, the battery life of such products also varies widely.
Electromagnetic and infrared, what kind of smart pen should we choose?
First of all, these two types of products have relatively mature technology and application support, as well as a relatively clear toB target user group. However, the channels for ordinary consumers to purchase such products are still limited, so it will take some time to popularize them.
Secondly, as an educational user, teachers and students, Pangpang believes that the electromagnetic induction recognition smart pen is more worth recommending based on the following three reasons:
The electromagnetic induction recognition writing system has good stability and long battery life. Take the bell-unlocking notebook used by Fatty Teacher as an example. During the writing process of nearly 1,000 pages of A4, there was no failure to connect or loss of offline data during use, and the comprehensive use time of up to 1 week is enough for the teaching environment. On the contrary, whether it is the Upen, which claims to be able to write continuously for 8 hours, or the Moleskine, which is priced at 2K, in actual use, you basically need to pay attention to the power at all times, and the app experience still needs to be optimized.
Since electromagnetic induction does not involve compact optical components, its drop resistance and durability are also better than infrared dot matrix products. Mr. Pang Pang's A4 version of the notebook has been repeatedly dropped by more than 1 meter, repeatedly impacted and squeezed by about 30 kilograms (yes, this is a masterpiece of a certain bear kid, I throw it, I press it, I sit!), and still function normally. It can also be used normally after being placed in a teacher's dust environment for a week. On the contrary, Upen and moleskine are easily scrapped due to falling or even just being squeezed inside the bag (I finally understand why a special pencil case should be designed for the product, but it is too late).
Although electromagnetic induction needs to be used with a special writing board (in fact, the weight is only about 100g), it can be written on any paper, which is enough to make the infrared dot matrix smart pen fail. After all, in the application of educational scenarios, post-cost control is very important. , Dot-matrix notebooks that cost tens of yuan a copy are really not suitable for long-term use by students, and the existing infrared smart pen products are basically A5 or B5 format notebooks, which are far less suitable for A4 format electromagnetic induction products.
