First of all, I apologize to Lei Feng.com for my late submission of my use report, but I decided to write this trial report after a detailed use experience!

First of all, open the box ︾

The packaging is black subject+purple logo, and I like this color match very much! Then the packing box is very strong, very firm, that is, it feels very hard to open it! It can't be opened for half a day, but this is also a good thing, which can better protect the product! Then you can see that the layout inside the box is also very solid, and the mouse will not even shake inside.

Mouse details picture

As can be seen from the above detailed pictures, the mouse is still carefully made, feels good, and the wire is also thick. It uses the kind of fiber wire that looks very strong, and the USB connector is also a very delicate gold-plated interface~

The following is its vein identification window and four infrared lamp beads

Go to the website to download the software //pc.cein.cc/ ︾

The color matching of the website is also black+purple, which suits my appetite!! Great praise!

I won't say anything about software installation. If you can't handle these things, you don't need to mix with Lei Feng! The following is the basic interface of the software and the basic use methods. There is nothing to introduce.

Well, there are some basic information in front. Here is my real experience!

I Software Basics

It can be seen that the interface of the software is pretty good, and the design is also good, but some small details still need attention (obsessive-compulsive disorder)

1. For example, in the basic setting interface of settings, you can see that the box for entering the password and the words in front of it overlap unharmoniously,

2. The file protection interface displays two buttons: “ Add File ” (The back one should be “ add folders ” ），

3. Click "Lock" in the file protection interface ” perhaps “ hide ” After the software is operated, whether it has been locked or protected is not displayed on the software interface

4. The sentences on the interface are incomplete when the software is used for the first time (you can see these problems in the picture I uploaded above)

II Quick login function of the website (to open the webpage, the default way of the software is to open ie Browser, auto login to web page)

I added some pages that I often use to test. The test results are divided into three categories.

one       Open directly ie Normal access and login to the website we want (very satisfactory results), such as Xiaomi Mall

(However, this is the account security management interface, which is not the Xiaomi Mall mentioned before. I don't know why. It may be that my account has not been verified.)

2. Click the website in the software interface to open the corresponding website, but instead of automatically logging in, you stay in the login interface (the interface for entering the verification code), such as Baidu Cloud, Baidu Post Bar, Youku, etc

Personally, I think the reason for this is the login constitution of the website's verification code, and we can't blame our software

three The page opened after clicking is a login interface of the website, but it is not the same as before. His account password box is empty! Nothing was filled in! Just open the login interface of the website, which means nothing! (The most serious problem) For example: Zhihu (what other websites haven't been found yet)

Summary of website login function: generally speaking, the use response is very good, the website opens quickly, and there is no problem with the login settings, but there are some small problems, such as Zhihu, and the number of associated websites is still limited, and the browser used together is only ie （ ie At least it's a browser I don't use very much.

Personal idea: First, we should do a good job in cooperation and coordination with the website. We must stop the problems like Zhihu again. Secondly, the website list should continue to be filled (which needs to be accumulated). Finally, it is about the browser, ie The share of is too small now. I hope the software can cooperate with other browsers (but it seems that only ie It can ensure that every computer has) for example, it can be developed google , Firefox browser plug-in.

III File protection function

The file protection function is very useful in windows After you select Hide in the system, you can't find the open record of the file ~~~ Very good, but we should pay attention to the small details mentioned in the first point before, otherwise it will affect the user's use!

However, the files protected by this software under Windows have not changed in the actual measurement under the Linux system! It can be used normally!

4、 Lock screen function

The lock screen interface is very nice!! Like one

A small accident occurred: On the lock screen interface, press ctrl+alt+a Screenshot（ qq A small episode occurs when screenshots are saved; The saved interface can be used to access any file in the computer and copy the file!!! I don't know which software it is bug…….

V Interesting Findings on Vein Recognition

At the beginning of use, I only entered a vein once. If I keep my hand on the mouse, I can quickly unlock the software every time. It is very useful, but if I take my hand off the mouse and put it on again (the finger position will certainly change), it will be difficult to unlock. I need to move my finger up and down to unlock the software. Then I suddenly found that the vein can be entered several times in the user setting interface, so I entered it five times again, and then used it again, feeling that the recognition speed was much better than before, but still could not reach the speed I wanted, so I repeated my middle finger from the fingertip to the root of the finger several times (about fifty Time, don't say I'm crazy, I'm just so headstrong!!) Then, as I expected, the software was unlocked as soon as I put my finger on it. Ha ha, I am as smart as I am. However!!! At night, my father had a whim and said to me that you had applied for a mouse trial. Let me have a look ~ I proudly handed him the computer and mouse (the computer is in the software lock screen interface). I said “ I'll open it for you ” My dad said “ Isn't it vein recognition? Let me give you a try! ” I swear “ You can't open it ” Then my father tried to get up. At first, he didn't open it, but suddenly suddenly!!! The computer turned on at once!!! I didn't believe it at first, but after many attempts by my father, he finally opened my vein verification software lock and lock screen at will! I didn't believe the fact that I called my mother to try, but the final result was that after a few minutes of trying, she also opened my lock!! At last, my brother tried to unlock the lock without any effort, almost at the same speed as me!! At this time, my heart is broken!! I can't believe the fact. After deep thinking, I guess it is because I input too many veins. Although it improves the speed of recognition, it also reduces the accuracy of recognition! So I immediately started to do experiments to verify my ideas. I charged the software and entered it five Secondary vein, the result is very obvious!! My family couldn't unlock the lock, but my recognition speed was still very slow. So I continued to do experiments to try to find a balance between recognition speed and accuracy. Finally, my results were 15~20 The number of entries can get the best balance while ensuring speed and accuracy. exceed thirty After several times, it seems that a threshold has overflowed, and others can successfully unlock it after many attempts!!

I don't know whether this is a problem with vein recognition technology or software, or whether it is inaccurate due to too much input in recognition technology. But I personally think it is necessary to point out that attention. Therefore, this discovery is specially proposed here. (There is no sense of praise or criticism, just objective questions. In general, the vein recognition technology is very good, with good accuracy and speed!)

VI About Mouse Hardware

It is also very good to use as an ordinary mouse. There is no problem, pe as well as Linux The interface can be used normally. The reaction speed and workmanship are both very good. It is definitely the quality of high-end mouse. There is no speed regulating button (but most people don't use it, and I don't play big games). The experience of using the game is also very good (I play some small stand-alone games). One discovery is that when I am crazy about doing experiments (the mouse has been identifying) The mouse will have some small heat, and it is easy to sweat in summer. Ps : The workmanship of the mouse is also very good ~~

VII Conclusion: (I have little experience in writing the evaluation, and my level is limited. I pointed out the problems directly when I encountered them. I don't know if there is anything inappropriate. The article is also quite long, but I did a trial conscientiously and wrote the evaluation conscientiously. I hope you will understand more about the bad points.) This is definitely a very good and innovative product, Very good experience! Although there are some small details that need to be improved, it is definitely a product worth trying!

Finally: I hope that the cein product can be better and better, and also that leifeng.com can be better and better.
