What Is UX/UI Design?

cover mic.jpg

User Experience (abbreviated UX) and User Interface (UI) have been buzzwords for a while. Especially in the last years, we have heard very often “no user experience, no product” or “user experience is everything”.

So, what are these terms that everyone wants to talk about and relate to? Do all these people really know what’s all about or they just claim to be “experts”? Do these terms mean something or are just industry buzzwords?

In this article, I’ll give you a deeper understanding of what UX and UI designs mean.

Why UX and UI have become so popular?

UX and UI design were originated in the late 1940s and gradually popularized with the development of computers. But as more and more companies competed in the same market and developed similar products and services, they had to find a way to differentiate and position themselves into the consumer’s mind. Therefore, they started to pay attention both to the feelings of users while using a product or service and to the way they created that product or service.

Frankly, I think user experience is the best standard to measure how good a product or service is. If users feel uncomfortable with your product and it doesn’t fit the best their specific needs, the customers will replace your product with a better one.

On the other hand, the user interface is about how you create that product or service. What you use for doing this and how it looks like.  Both are interconnected and are equally important. Moreover, both are business angles.

So, what is UX design?

UX design is the human-first way of designing products. According to Wikipedia’s definition, “user experience design (UXD, (UX, UXD, UED or XD) is the process of enhancing user satisfaction with a product by improving the usabilityaccessibility, and pleasure provided in the interaction with the product.“

Until here, everything is clear, right? As you can notice, I haven’t brought into the discussion any tech or digital reference. In fact, in its current form, the term was introduced by the cognitive scientist Don Norman – the founder of Nielsen Norman Group - in the late 1990’s. He declared that "User experience" encompasses all aspects of the end-user's interaction with the company, its services, and its products.”

This means that regardless the industry, UX design includes any and all the interactions between a potential or an active user and a company. As a process, UX could be applied to everything, from a lamp to buying a smartphone or a car.

If we convert these ideas into the web or mobile spaces, the user experience is about how a person feels when interfacing with a website, a web application or a software, and generally speaking, with any form of human-computer interaction (HCI).


People who work on UX (UX designers), study and evaluate how a user feels about a system, looking for things such as usefulness, efficiency, easy of use, credibility, accessibility, the value it provides, how easy is to find and so on.

UX design is about helping users to positively answer all the questions mentioned above.

What does a UX designer do?

Good question. As UX design is the process of developing and improving quality interactions between a user and a system, the role of a UX designer is complex, challenging and multi-faceted. Part marketer, part designer, and part project manager, a UX designer performs various tasks and has a never-ending job.

Below I’ve summarized six main tasks of a UX designer:

1. Product research

Product research (that also includes the user and market research) is the starting point for every great UX project. It is the foundation for great UX designs because it allows the designers to collect data, convert them into quantitative and qualitative information and make information-based decisions.

During this stage, the UX designers gather information about:

  • users: goals, motivations, needs
  • industry standards and competition
  • identify opportunities for the product in the given area.

2. Create personas and scenarios

Based on the research they’ve done, the UX designers identify the key user groups and create representative personas. A persona is a fictitious identity that reflects the users' groups you are designing for. So, instead of thinking about general categories of users, such as social media users, for example, give them name and try to describe them as detailed as possible.

After identifying the personas, you can create the scenarios. Whether you redesign an app or a website, or you create the new ones, it’s important to think about all the steps a user could make while interacting with your product.

3. Information Architecture (IA)

Once all the researchers are done and personas created, it’s time to design the first Information Infracture (IA). This means to create the structure for a website, app or other product that lets the users know where they are related to the needed information and which are the next steps they have to make. For example, when you sketch a menu, you are practicing information architecture.

4. Create wireframes

Once the IA designed, UX designers may create the wireframes. They are a low fidelity representation of the website or app and should represent each screen or step a user might take during the interaction with the product.

At this point, the focus is on determining the flow and the key features to keep in and which to leave out or revise later. UX designer also has to identify all the small interactions that could appear and create the overall experience of users.

5. Prototyping

After designing the wireframes and deciding the final structure and flow, UX designer can start prototyping. This means he’ll create a middle to high fidelity representation of the final product, whether it’s a website, an app or a software. 

Even if the prototype might not look exactly like the final product, it should be very similar in intention. It can be used to its full potential in users testing, allowing them to experience content and test the main interactions with the interface in a similar way with the final product.

6. Testing

Testing is a very important step during the UX design project and helps UX designers find out what problems might occur during the user’s interaction with a product. One of the most common (and useful) ways for testing is to conduct in-person user-test. This way, you can observe the user’s behavior by analyzing the verbal and non-verbal feedback, a better user experience may be created.     

In conclusion, UX design is focused on user’s journey to solve o problem and is centered around emotions. Then... 

What is UI design?

UI design is just a piece of that journey.

As I mentioned at the beginning of this post, UI design stands from User Interface design and is about how a product looks and functions. Like UX design, UI design has a complex, challenging and multi-faceted role. It is focusing on translating a product’s development, research, content, and layout into an attractive, guiding and responsive experience for users.

You can think about UI design in terms like these:

User Interface Design = Visual Design + Interaction Design

While Visual design is the look and feel of the product, Interaction design is the way people interact with your product, whether it’s website, app, video game or software. For example, when you navigate on a website, the visual design is all about the colors, shapes, fonts, images, balance, hierarchy displayed on this website. Also, Interaction design is about what happens when you navigate on the website. If you click on a button, does it change in a noticeable way, so you know you’ve been successful?     

What does a UI designer do?

As UI designer, you need to go hand-in-hand with the design. This includes designing the screens and creating visual touch-points, as well as the interactivity behind them. The UI designer is also responsible for creating the consistency, meaning creating the style guide or visual language that will be used across the whole product, on all devices.

Here are some key responsibilities:

  • Design each individual screen with which the user will interact (colors, spaces, hierarchies, visual patterns and micro-interactions for creating an intuitive user experience
  • Considering how the product will display on different devices – responsive design
  • Design UI elements such as buttons, icons, scrollbars, and sliders
  • Choosing the right colors, imagery, and typefaces
  • Creating animations
  • Design the interactivity of each UI element – for what does a button do when you click on it
  • Assuring the consistency and the familiarity for the user by creating the style guide to be used across all the devices
  • Prototyping and testing – as UI designer, it’s important to repeatedly test your designs, till you are sure that the final product will check all the aesthetic and functionality goals

Is one more important than the other?

UX and UI design are different concepts. However, you have to combine both if you want users to be interested in your product or to convey certain information to them.
