[Unpacking]

The cardboard material is used for box packaging, and there is not too much printing on the front except for the logo of CEIN, which is simple and elegant.

Some general information on the back of the box: packaging content, bar code, mouse color (this model is dark), etc

The built-in design of the inner box and outer cover is very tight, which wastes some effort. If there is a finger groove on the side, it will be more intimate

It is lined with foam sponge, and the upper and lower bottoms are pasted with flannelette. The cut surface is uneven, and the process is slightly rough

The plastic surface is painted, and the touch is exquisite

Common material fault, poor wear resistance

Or in consideration of the accuracy of vein scanning, the mouse pinching design is adopted, and the palm is suspended

But the mouse is light in texture, and the little finger of the thumb does not feel sore when used for a long time.

Installing near infrared light makes this mouse slightly wider than other mice, and girls with small and slender hands may not be suitable

Boys and Habits Middle Finger Roller Right click on ring finger is harmless

However, since the audience of the mouse includes the elderly, using comfort must be one of the priority conditions. It is necessary to add ergonomics to the subsequent improvement and production, such as the left side of the mouse has a thumb depression, the infrared lamp uses a slope design for internal testing, and the main contact surface uses skin like materials.

Nylon mouse cable

It has high abrasion resistance and is not easy to knot, but its texture is hard. The user guide does not specify the length of the mouse line. The actual measurement of 170cm is enough for normal use

After installation, the shortcut of Wukong will be automatically generated,

The next step is to register finger vein: input user name and standby password.

Rough problem: During the final verification of vein unlocking, the user did not put his hand on the mouse, but the authentication was still successful, driving the problem? Hard wound?

After verification, we successfully entered the main interface, including 37 commonly used websites such as Meituan, Taobao, Douban, Baidu Netdisk, etc. (I believe they will continue to increase in the future)

In IE Opera, which clearly saves password cookies, the vein scanning function of Taobao, Alipay and Baidu Post Bar is only successful when ie is used, and only Baidu Post Bar is successful

Taobao and Alipay both prompt login failure due to the need to enter the verification code.

The existence of the verification code has largely blocked the application of the automatic login function of venous scanning. If the second priority is to cancel the automatic login, the convenience of manually entering the verification code will be greatly reduced

How to exempt the input of verification code in intravenous login is a barrier for technology popularization. Since we can't get around, we need to discuss solutions with the cooperation website~

In addition, this mouse has two functions: file protection and screen protection.

File protection can be locked or hidden as long as the file or folder to be protected is added to the list in advance.  

It's easy to use the personal test

As for the screen saver function, it is stuck and lost again in the test

There is a phenomenon of successful unlocking without holding the mouse

To test whether sweat affects the results of vein detection

I use a cotton swab dipped in normal saline to wipe the index finger that needs intravenous test

The results did not affect the identification

Summary

Overall, not as satisfactory as expected

Maybe it's too high expectation. After all, it's a product that has not been popularized in the early generation
