UI (User Interface)

The user interface (UI) is the heart of every user’s interaction with digital products. It affects their comfort and efficiency. The UI includes all visual and interactive elements a user comes into contact with on websites or in apps. From buttons and menus to icons—every element plays a key role in how the user perceives and uses the product. A quality UI ensures intuitiveness, functionality, and aesthetics, improving the overall user experience.

What is a user interface?

The user interface (UI) is a design discipline focused on the interaction between a user and a product, such as a website or mobile app. It is part of the overall technology experience that enables users to easily perform desired actions.

Definition and importance of UI

UI includes all visual and interactive elements a user encounters. These include buttons, icons, text fields, menus, and other components that ensure smooth navigation and intuitive control. Quality UI design significantly improves user satisfaction and the efficiency of using a product.

The difference between UI and UX

It is important to distinguish between UI (User Interface) and UX (User Experience). UI focuses on the appearance and layout of elements, while UX focuses on the overall user experience, including feelings and reactions. Although the two areas are closely connected, they have different goals.

UI focuses on visual design and interactivity.
UX focuses on the overall experience and user satisfaction.

Key elements of the user interface

The user interface consists of various elements that together create an intuitive and friendly experience for users. Each element has its purpose and contributes to the overall efficiency of navigation and interaction.

What are the main UI elements?

Buttons and links – used to perform actions and navigate between pages or sections.
Forms and input fields – allow users to enter data and communicate with the app.
Menus and navigation bars – make it easier to access different parts of a site or app and help maintain clarity.

The combination of these elements should be well thought out to ensure comfortable control and smooth interaction with the product.

What are the principles of effective UI design?

When designing an effective user interface, it is crucial to follow certain design principles that ensure the interface is clear, intuitive, and pleasant for users. These principles help create a user-friendly product that is easy to use and accessible to a wide range of users.

Simplicity – keep the interface as simple as possible and free of unnecessary elements so users can easily understand how to use it and focus on primary tasks.
Consistency – use the same style and elements across the interface for easy orientation, enabling users to adapt quickly and recognize similar actions or functions.
Clarity – ensure sufficient spacing between elements and a clear content hierarchy, which increases readability and makes navigation easier in an app or on the web.
Responsiveness – adapt the interface to different devices and screen sizes, allowing users to use the app comfortably on desktop, tablet, and mobile.
Feedback – inform users about actions and changes through visual or audio cues, ensuring they know what is happening and the result of their interaction.

Trends in UI design

In recent years, the field of UI design has evolved rapidly due to changes in technologies, user expectations, and design practices. Modern approaches focus on simplicity, functionality, and aesthetics. Users today expect interfaces to be not only pleasing to the eye but also efficient and accessible.

As technologies develop, the way UIs are designed is changing. What are the current trends?

Modern approaches – minimalist design that focuses on a clear and simple interface, and dark mode, which has become popular for its ability to save battery and reduce eye strain.
Technology and tools – software like Figma and Sketch are now standard for prototyping and UI design thanks to real-time collaboration and advanced features.
Use of AI – implementing artificial intelligence to personalize user experiences.
Microinteractions – small animations that improve interactivity and make apps more pleasant to use.
High adaptability – designs that adapt to different platforms and devices, ensuring a seamless experience across the entire ecosystem.
Use of color and typography – bold and creative combinations of color and typography that capture attention and strengthen visual hierarchy.

These trends are shaping the future of UI design and make it possible to create modern, user-friendly, and innovative interfaces.

Bonus: which books to read?

In user interface (UI) design, it is essential to consider not only technologies and design trends, but also user psychology. Understanding how people interact with digital products—their needs, behaviors, and expectations—is vital to creating an effective and friendly interface. When designing a UI, it is therefore important to combine technical knowledge with a deeper understanding of human psychology.

UI: what to read?

The Design of Everyday Things (Don Norman) – a classic in design that focuses on how to create products that are intuitive and user-friendly. The author explains the importance of functionality and clear design that aligns with human thinking.
Don’t Make Me Think (Steve Krug) – a practical guide for anyone interested in web usability and UX design. Krug emphasizes that design should be simple and natural so users don’t have to think hard about how to interact with a product.

Literature on user psychology

Thinking, Fast and Slow (Daniel Kahneman) – the author offers deeper insight into how people think, make decisions, and which cognitive shortcuts they use. Knowing these principles is key to creating a UI that matches users’ natural behavior.
Influence: The Psychology of Persuasion (Robert B. Cialdini) – this book focuses on techniques that influence people’s decisions and behavior. Understanding these techniques is useful for designing interfaces that communicate effectively and motivate users to take desired actions.
