Do you know that UI and UX are not the same Concepts? True, they are closely related, even impregnated with each other and rarely exist without each other. Do you want to study in detail the differences between the design of the user interface and that of the UX? This Article gives You such an Opportunity.

We believe that it is impossible to become an experienced Designer without knowing exactly both terms. We promise that you will like some definitions; some of them will seem serious and thorough. The information you are going to read is lively and informal, because we base it on the thoughts and expressions of real web developers. We wish you a lot of fun reading.


The Difference between UI and UX Design


Let’s start with the definitions, because it’s always easier to continue if you know exactly what you’re talking about.


The user interface is the space in which the interaction between man and machine takes place. The purpose of this interaction is the effective use and control of the machine at the end of the user and the return of the machine that helps the operator to make operational decisions. In other words, a user interface is the system by which people (users) interact with a machine. The user interface includes hardware (body) and software (logical) components. User interfaces exist for different systems and offer a way to:


An input that allows users to manipulate a system;

Output that allows the system to display the effects of user Manipulation.

The main goal of the man-machine interaction technique is to create a user interface that makes it possible to use a machine in a simple (intuitive), efficient and pleasant (user-friendly) way to achieve the desired result. In fact, it’s great if the operator needs only a minimum input to get the desired output, and also the machine minimizes unwanted expenses for man.

With the increasing use of personal computers, it is generally believed that the term user interface means graphical user interface, while industrial control panel and machine control design are more commonly referred to as human-machine interfaces.

Types of User Interfaces

There are many types of user interface, but we will only mention those that relate to computers, because you do not need to clog your brain with information that you never need.

Graphical user Interfaces (GUI) they accept input via peripherals such as a computer keyboard and mouse and provide an articulated graphical output on the computer screen.

Web user interfaces or web user interfaces (WUI) they accept inputs and provide outputs by generating web pages transmitted over the Internet and displayed by the user using a web browser program. New implementations use Java, JavaScript, AJAX, Adobe Flex, Microsoft .NET or similar technologies to provide real-time control in a separate program, so no traditional HTML web browser needs to be updated.

Administrative web interfaces for web servers servers and networked computers are often called control panels.

Touchscreens these are screens that accept input by pressing the finger or stylus. Used in an increasing number of mobile devices and many types of retail outlets, industrial processes and machinery, self-service machines, etc.

User interface design is the actual interface design that would best facilitate for a great seamless, enjoyable and rewarding interaction between the user and your product. Observing the behavior of users and making informed decisions based on the data collected during their observation is a large part of the UI design work. User interface design is more like a profession, because you really build something beautiful and tangible with the skills, knowledge and techniques gained from experience. Some UI designers use tools like Photoshop, Illustrator, Fireworks, Film 4D, ZBrush and lots of pen and Paper to get things done. It is unlikely that you will become a good user interface designer without understanding what UX is.



The user experience includes the behavior, attitude and emotions of a person when using a particular product, system or service. The user experience includes the practical, experiential, effective, meaningful and valuable aspects of human-computer interaction and product ownership. In addition, it includes a person’s perception of such aspects of the system as usefulness, ease of use and efficiency. The user experience can be considered subjective insofar as it concerns individual perception and thinking in relation to the system. The user experience is dynamic because it is constantly changed over time due to changes in the terms of use and changes in individual systems, as well as the wider context of use in which they are located.

The design of the user experience begins with a good understanding of your user base, the generation of ‘Personas’ for the dominant character types within your user base and the definition of specific requirements for each project. Sort your information architecture by generating a data inventory and organize a solid information hierarchy that would help a lot at the beginning of the prototyping process. Choose the best prototyping method, which is both cost-effective and allows you to quickly and easily collect and repeat your feedback. Prototypes can be horizontal (wider features, shallower features), vertical (deeper features, narrower features), t-prototypes (much of the design is carried out flat, while some features are implemented at great depth) and local prototypes (used to develop design alternatives for a particular interaction model). After selecting a suitable prototype, the iteration process begins. This usually varies a lot between working on software products, services or industrial design projects.

Thanks to Wikipedia and question pages, we now know exactly what the user interface and UX are. As you can see, these are two absolutely different ideas, and every professional Designer should know that the gap between them is as big as the Grand Canyon.
