How is called this competence (Who is it)?

Hello

I would like to learn/are competent to design interfaces based on user data, i.e. to design interfaces:
logic worked
- so the user could quickly obtain the desired result from the system

Please tell me how is called the area/competency?

1.I am at this stage not interested in the competence associated with the design including how beautiful to paint or implement some kind of button or function, what are the dimensions of the fields. Interested in the above mentioned competence.

2. What to study? What kind of books?

Examples of the work of the expert with this competence:
No. 1
Developed electronic document management system.
Example: developed an electronic document, the required form was missing, so it did "how did". Like all information on the form, but it is not logically developed.
In the course of user testing, we learned that:
the user, for example, will first indicate the date for which the document is formed, then usually indicates your organization, then your Department - and therefore these fields need to build according to the script, ie, to make first. Nodding a part of a document to alter.

No. 2
Software product no, at the stage of concept or development.
Example:
There are functional requirements for the product.
Identify the users ' preferences, goals, etc.
Generated user scripts
Developed the concept of the program
Test the concept on users
development of a prototype
The tested prototype including user
and t..D.

UX-designer. Or just a designer.
UX specialist and designer are different people. But often in small companies, these positions combine together to save. - Declan.Grady10 commented on August 19th 19 at 23:30
: De facto. Why do you insist on the word "specialist"? Proper arrangement of controls is design. Somehow there is a perception that the designer is nothing but thumbnails graphics do not have to. Moreover, it is typical only for CIS. - Letha_Kuhn commented on August 19th 19 at 23:33
against UX-designer I have nothing against and I agree with you. However, simple designer is another. - lee_Morar commented on August 19th 19 at 23:36
In my understanding it is a General name for all kinds of designers, as a "programmer" for your region. After all, between some frontenders and embedded developer is the same abyss of difference, ranging from tools and ending with theoretical training. But both do one program. - Letha_Kuhn commented on August 19th 19 at 23:39
designer = designer, designer, designer, designer, designer, draughtsman, draftsman, designer clothing, designer, decorator - lee_Morar commented on August 19th 19 at 23:42
: they were talking about "designer" and not about "designer". - Mauricio_Auer1 commented on August 19th 19 at 23:45
: what do you mean! And whence in the Russian language did the word "designer"?? - lee_Morar commented on August 19th 19 at 23:48
: You won't believe, but the Russian language has borrowed words, which are not always identical in meaning to the original. - Mauricio_Auer1 commented on August 19th 19 at 23:51

Previously, it was called MMI (Man-Machine Interface), and then a slightly modified name HMI (Human..). It is necessary to take into account the requirements of ergonomics.
Now what? do you? - Declan.Grady10 commented on August 19th 19 at 23:32
: and now nothing - this doctrine has existed for years, so about twenty, and died five years ago.
since then, actively developing the direction of "how to force user to click three times instead of one where to push more of the drop-down menus so that they overlap each other and closed the exit button" - Letha_Kuhn commented on August 19th 19 at 23:35
