UI's full name is User Interface, the Chinese translation is user interface, interface in the dictionary definition is: the contact surface between the object and the object.

So UI design is always divided into physical UI and virtual UI, to the car for example, the steering wheel, dashboard, center control belongs to the user interface belongs to the physical UI; and we often say in the Internet UI design belongs to the virtual UI.UI literally only includes the user and the interface, but it also includes the interaction between them, so UI design can be divided into three directions: User research, interaction design, and interface design.

After understanding what UI design and his three directions of work, we can think about how to complete the UI designer a job content, first of all, we first say that we can see the interface design, interface design is the most intuitive part of the UI work, the user only need to look at the user can feel that you design the interface to give a person a feeling of excellent visual designers, can give a person a sense of the screen between the square inches of the screen to give a person a feeling of the interface. Excellent visual designers can convey a different feeling to people on the screen between square inches, as if you look at the interface of JD.com and look at the interface of Tmall can feel a different feeling, even though they are all e-commerce APP, and the goods sold are generally the same. Interaction design is not so obvious, the user clicks on a button, which can be called interaction, as for which button we want the user to click, after clicking what kind of prompt animation to let the user understand what kind of operation I carried out, as well as in order to complete the user's purpose of the process is how it belongs to the task of interaction designers or product managers. Of course, different groups of people have different operating habits, such as the elderly do not like to see small fonts, young people feel that the font is too large, you have to scratch the screen several times in order to see the content of the whole too tired.

This time we need to carry out user research in the pre-design phase, we want to do a product can be APP or physical, we first need to solve the user's needs, and then study the user is what kind of people, what are their characteristics, because of what they have these needs, they need us to provide what services. So after the feasibility study is passed, user research is the beginning of our UI design work.

With the advent of the big data era, the collection of big data can help us to collect user habits, such as the collection of a person a week to use what type of software for the longest time, in the use of this software time, location and watch the information category, so as to collect what kind of age group and occupational groups division. This will enable us to conduct more in-depth research on the user population.

In the work, if you go to the company is just beginning to prepare for the development of an APP or functional modules, it may involve user research, but generally speaking, fresh graduates and just change the profession is no way to directly take over the work of the user research, because just enter the industry, the lack of product thinking, but also do not have to experience and study a certain number of products, so the interaction designer is not competent to do the job. Interaction designers are also not competent, the most common is to become a visual designer. Visual designers are facing a situation in the absence of aesthetic now, that is, even if you are very attentive to polish a page, people who are not in the industry, or even the same as the newcomers to the industry, it is very difficult to see the fineness and attentiveness of your page, so it has always been visual designers are also jokingly referred to as aesthetics, but also in the second and third tier cities, because the visual design does not have so much theoretical support, so it is a Alternative is very high position, due to see the effect of good or bad, so the bosses will feel who to do are almost the same, but do not look down on the artisan because I say so, in fact, the artisan job is not as long as you will PS and AI can be competent, excellent artisan can be the highest efficiency to complete the need for a variety of design work.

Many students do page, with the thinking of graphic design, such as doing a page, the final result is not ideal, but due to the lack of theoretical knowledge do not know how to refine the page, not to say that you should not use the thinking of graphic design when doing a page, a lot of knowledge in graphic design is also applicable to UI design, for typography and graphic design theory will of course also be used. and graphic design theory will of course be used in the layout of the page and icon design, but there is a difference is that the UI design of an interface is not the same as the graphic design of the final output of a complete work, you are responsible for the page, maybe just a link in the whole project, as if a blank page, you do not need to use Leonardo da Vinci to paint the Mona Lisa the kind of determination to design, right, deadlocked three years finally! The design of the interface may update the hand-drawn out of the not too far.

We then do interface design to understand a central idea, we do this page, in order to first complete our business needs, for example, you do a purchase page, a page before the payment, due to the design is too colorful, eye-catching, the user a click to somewhere else, resulting in the final sale of the things, then you can not be called the interface design of this Good design, after meeting our business needs, we need to meet the user's demands, if an APP just to make money, and did not meet the user's needs, the user has what reason to keep using your APP it, for example, microblogging has been charging money, but do not give the user to send microblogging, you have to continue to use it? If you want to donate money you can actually go straight to charity.

Lastly, it is to optimize the user experience, so that the interactive animation is more comfortable, the color with the eye, which is to do the page when a whole complete logic.
