There are lots of misunderstanding among designers and developers. There are also a lot of questions related to UI and UX for beginners. Often, simply because people do not know the essence of the UI/UX concept and, not knowing what they are talking about, call things by not their own names. Let's put the point once and for all and understand in clear language what "UI/UX design" means.
Whether you press the buttons on an arithmometer, turn the grindstone handle or make a swipe across the screen of the smartphone - all these are the interfaces through which you interact with the mechanisms. The interface does not need to be digital at all. So, the goal of the UI/UX designer is to bring the user to some logical point in the interface. Make the user to reach his goal.
UX is a User Experience. That is, this is what the experience / impression the user receives from working with your interface. Whether he is able to achieve the goal and how easy or difficult it is to do so.
And the UI is the User Interface (verbatim "user interface") - what the interface looks like and what physical characteristics it gets. Determines what color your "product" will be, whether it will be convenient for a person to get a finger in the buttons, whether the text is readable and the like ...
UX / UI design is the design of any user interfaces in which ease of use is as important as the appearance.
The direct duty of the UI/UX designer is, for example, to "sell" a product or service through an interface. It is on the basis of the UI/UX designer's work that the user makes a decision: "To be or not to be?" Like or dislikes. Buy or not buy.
In fact, the goals of the designer can be different. It is not necessary to "sell" something. But I specifically do not want to use too abstract phrases to make this text understandable to beginners; so that the style of presentation does not turn into an anthology on the programming language of the sample of the 90s.
UI/UX design does not apply only to smartphones and websites. Moreover, the profession of UI/UX designer has existed since time immemorial. Just before it was not called. More precisely, it used to be not called at all, but was part of other professions.
Here is the first example: when Wilhelm Schickard in 1623 invented the machine, he was already a UI/UX designer.
It was he who invented what toggle switches and in what sequence the person should twist to get the result of the calculations. And he also thought out in what logical order they would be located. Yes, and even thought out how all these pens will look. He created an interface for interacting with the machine.
UX designer plans how you will interact with the interface and what steps you need to take to do something. And the UI designer comes up with how each of these steps will look. As you can see from the examples above, UX and UI are so closely related that sometimes the line between concepts is washed away. Therefore, both UX and UI are usually dealt with by one designer and his profession is written through /.
UI/UX design is now one of the most popular professions in the digital industry. How long it will be required depends on the development of this industry. And, apparently, it is only gaining momentum.
UX and UI are not trends. Technologists are developing. Demand for sites is growing. Digital applications appear as mushrooms. And the design and development tools are simplified so much that almost any person without programming knowledge can "make a business card on his knee". That's just this site should somehow look like. And not just as an abstract framework of text and buttons. Here programmers also need help from UI/UX designer.
