preface

Since we entered the digital era, more and more of our writing opportunities have been deprived of by endless technological products. Do you occasionally want to find the feeling of pen tip walking on paper? For the problem of returning to writing, from Bookie Board Jot to Apple Pencil+iPad combination or YOGA Book, various manufacturers have never stopped exploring it, because they all have the advantages of being easy to organize, save, share, and so on, which are beyond the reach of traditional paper materials. However, not to mention how much writing experience their touch screens have sacrificed, the price of hundreds of thousands of yuan has positioned them as high-end businesses and turned many of us away. Are there any other solutions? yes!

Elfinbook is such a product with both paper-based writing experience and relatively low price. Using an innovative working mode of writing on paper+scanning and storage of smart phones, it has achieved great success in Taobao crowdfunding and will be officially launched soon. Today we will unveil its mystery.

Unpacking

Elfinbook， The white paper box is used for packaging. In addition to the line "Elfinbook epoch-making smart notebook", three use effect pictures are designed at the most eye-catching position of the packaging, and some product features are listed below. On the whole, I think it is not simple enough. There is less force, but the level is very clear and beautiful.

However, however! The outer packing box is soft and thin, so that when I got it, the whole box was full of wrinkles, which somewhat lowered the overall image, or maybe I had a high expectation of it. It was originally a notebook focusing on environmental protection. Well, refuse to over pack.

After all, a box is a box. When you open the box, the contents are very simple: a notebook, erasable pen, unreadable instructions, and app member activation card.

The notebook looks no different from an ordinary notebook. The plastic cover does not have the business atmosphere of leather texture. The logo of Elfinbook is printed on it, which is very scientific and visual. The traditional way of punching and pressing rings is used for binding. The binding of 40 pages of the whole book is very neat, and the printing quality of the grid lines inside is also very good. Each page is neat and even, which can be said that the workmanship of the whole book is very good.

Experience

"Elfinpen" does not exist

Previously, the manufacturer said that this smart notebook will be provided with a "magic" erasable pen, so that our notebook can be reused. After receiving the product, the original gift was a very common Japanese brand erasable pen. You can use the rubber head on the pen to erase your handwriting. This is not very high-tech, not today's leading role, not much introduction.

But I still need to open my mind here. Since Qihui Technology's Elfinbook has made such great achievements in the crowdfunding stage, it should consider designing its own erasable pen "Elfinpen". I don't know if there is any technical difficulty. And as a real consumable, could you consider giving away one more.

The legendary "stone paper"

Stone paper can be said to be a highlight of this book. Maybe many people do not know the concept of stone paper. In fact, stone paper is a new material between ordinary paper and plastic produced by replacing traditional pulp with limestone and some polymer materials. The use of stone paper as paper has brought waterproof and durable features to this notebook, and the use of this stone paper has also made certain contributions to environmental protection.

The thickness of this stone paper is similar to that of ordinary A4 paper, but it is much softer than A4 paper and has certain ductility.

When I actually wrote, I found that the paper would slide slightly with the pen tip due to its soft texture, which made the characters a little strange and needed a little adaptation. Moreover, because of its irreversible extensibility, if you write with a little force, you will leave a dent. Obsessive compulsive disorder is unbearable. I wonder if there is any way to improve it.

(There is light on the side, the real visual effect is not very obvious, but it can be felt)

The waterproof property of stone paper is more useful. Because we want to digitally store notes, the words written on them must be erased. This waterproof material undoubtedly increases the life of the notebook. We will talk about it in detail below. Who doesn't want it to be written more times?

APP -- "epoch-making intelligence" is here

What really makes this book "intelligent" is actually on this Elfinbook APP, so we should focus on it. IOS and Android platforms are available, which is also convenient to use. The function of APP is to scan the content on the notebook to the mobile phone, convert it into pictures or PDF files after processing, save it or upload it to the cloud with one click.

The scanning process is very convenient. You can take a single picture, or scan multiple pages continuously, or import notes you want to scan from an album. The only requirement is to clearly and completely present the identification frame of the notebook in the picture. If the software fails to correctly identify, we need to manually frame the content range.

The scanned image can be selected from three modes: original image, black and white, and enhancement. The effect is as follows:

Here I have made another small test to see how its scanning effect is under different use environments.

First, the vertical angle and even light without shadow:

The scanning effect is very good, the border recognition is very accurate, and the text everywhere is very clear.

However, in our daily use, we can not always achieve the same uniform light as I did when shooting. Let's take a look at the scanning effect when there are shadows:

From the original image, we can see that there are heavy shadows in the lower left corner of the screen, but from the processed image, these shadows have no great impact on the recognition of the border and the final image quality.

Next, I tested a more severe situation - scanning notes at a very oblique angle and uneven light irradiation conditions:

From the scanning results, the software can still identify the frame more accurately and restore the note content clearly. It can be seen that its algorithm is relatively powerful, at least it can easily deal with various situations we use everyday.

The scanned file can be saved in an album as a picture, or a PDF document can be generated. In the unregistered state, the generated document will have an Elfinbook watermark.

Click Register, the verification code failed to be sent, and then register again, the verification code failed to be sent? I asked the partners who were evaluated together. They had some problems when receiving the verification code. I hope it can be improved after the official launch.

Files are stored in a tree like way in Windows, which is convenient to sort out. The built-in search function also allows you to easily and directly locate the files you want. This is the biggest advantage of this laptop over traditional laptops.

Remove handwriting - another "new" Elfinbook

For the notes that have been scanned and backed up, we can erase them. Here, the manufacturer has given three solutions - wiping with the rubber tip of the pen, wiping with a wet paper towel, and heating with an electric hair dryer.

Obviously, the rubber head of erasable pen is designed to erase individual writing errors for you. If you have the courage to erase the whole note with it... Good bye, little brother!

OK, be serious. Before actual use, I prefer to use a hair dryer to heat my notes. This is because of the characteristics of this erasable pen. When the ink reaches a certain temperature, it will fade into colorless.

This kind of removal method has almost no loss of paper, which means that you can write more than once. The disadvantage is that you need a hair dryer, which does not exist in many university dormitories.

If you give up the first two options, try using a wet paper towel. It has proved that its waterproof ability is beyond my imagination. The handwriting will be easily erased, and the next page of the paper or even the back of the page will not be a little wet. Of course, the paper will not be deformed or wrinkled. Wow, black technology.

I originally planned to do an extreme test to see how it could withstand my several rounds of "destruction", but I repeatedly wrote it seven or eight times, as if the paper was still without any loss. In this way, as long as you are gentle enough about it, the number of repeated writing is far more than the ten times claimed by the official, which undoubtedly improves the cost performance and praise!

Summary

Elfinbook adopts the combination of repeated writing on paper+scanning and backup by smart phone, which not only solves the problems of poor writing experience and high cost on electronic screen, but also solves the problem of inconvenient use of traditional notebook+scanner combination. It is very suitable for students, painters, designers and other people who need a lot of paper writing and a lot of manuscript storage.

Since it has not been officially launched for sale, the manufacturer gives us a reference price of 89 yuan, while the price of similar traditional notebooks is about 8-9 yuan. If we only write 10 times on average, the cost performance of this notebook can be the same as that of ordinary notebooks. If there is a discount after the launch, plus a series of functions that can backup notes, Its competitiveness in the market is quite strong.

To sum up, if you are targeting business, you only need to record some simple words occasionally. Maybe this Elfinbook is not suitable for you to buy; And if you have a lot of writing and backup needs, or just want to experience the feeling of writing again and retrieve the good memories of writing, then you might as well consider this "epoch-making" Elfinbook.
