What is the difference between UI and UX design?

UI (user interface) design and UX (user experience) design are distinct but interconnected digital design disciplines. While they are often used together, it's important to understand their meanings and roles:

UI Design: UI design refers to the visual and interactive aspects of a digital product or interface that users directly engage with. It focuses on the aesthetics, layout, and presentation of elements such as buttons, icons, typography, colour schemes, and overall visual style. UI designers are responsible for creating a visually appealing and cohesive interface that is aesthetically pleasing and aligns with the brand's identity. In addition, they ensure the interface is intuitive, easy to navigate, and visually engaging.

UX Design: UX design, on the other hand, encompasses the overall experience and usability of a digital product or interface from the user's perspective. It involves understanding user behaviour, needs, and goals to create a seamless and meaningful experience. UX designers conduct research, develop user personas, and create user flows and wireframes to map the user journey. They focus on enhancing the usability, accessibility, and efficiency of the interface, aiming to provide a positive and satisfying experience for the user.

While UI design primarily deals with the visual aspects, UX design takes a broader approach, considering the entire user journey and interaction with the product. Both UI and UX design are essential for creating successful digital experiences. CX design ensures the interface is visually appealing and easy to use. In contrast, UX design focuses on delivering a satisfying and user-centred experience by addressing usability, functionality, and user needs.

In practise, UI and UX designers often collaborate closely, with their roles sometimes overlapping. The ultimate goal is to create a harmonious and delightful user experience by combining the principles of effective UI design with the insights and considerations of UX design.
