UI (User Interface), Chinese name "用户界面".Ps：(Baidu) UI refers to the overall design of the software's human-computer interaction, operation logic, and interface aesthetics.

The wave of the Internet, whether it is the front wave, or the back wave has never stopped. You often see the "Internet +" such a combination of common interpretation of the "Internet +" is "Internet + traditional industries", but this is not a simple addition of the two, but the The use of information and communication technology and the Internet platform, so that the Internet and traditional industries to carry out in-depth integration, to create a new development ecology.

What is the close connection with UI in this?

The traditional industry to the Internet, certainly need to use an interface to display, even if it is just a simple web page, and every Internet product whether PC or mobile, whether traditional or non-traditional industries, the final presentation of the UI interface for the user to use as a basis for viewing. This is not only to visual output, but also good interaction and user experience.

As an example, let's talk about the call answering thing that we usually don't pay much attention to.

Apple phone in the state of not locking the screen, caller ID, answer the phone on the right side of the display green, hang up the phone on the left side of the display red. In general the right hand to take the phone, thumb operation, green is to answer the phone, this is our regular operation, the use of high frequency, so in the right side closer to the thumb, and hang up the phone frequency is not high so in the left side farther.

But if the red button and the green button were to change places, it wouldn't really affect the vision, but it wouldn't be a good experience, and you might hang up the phone at any time by mistake.

The UI is everywhere in our lives, no matter how big or how small, and it's all there in the experience that you see and touch. So UI is not just about aesthetics, it's also about visualization and user experience. And users are very picky, the demand for visual and experience needs are constantly changing and improving. So this also creates UI designers such as UI designers do not need to knock the code, but still can get a high salary Internet positions.
