The Intersection of UI and UX: Effective, User-Centered Design

How Are They Related?

There is certainly a need for complementary work in usability projects. The common ground is always a focus on the user, regardless of the roles played by Product Designers, UI Designers, UX Designers and other communication professionals. But what else connects them from a technical perspective?

The Role of UI

A UI Designer’s work focuses on the interface and usability, based on established heuristics and standards for good user experiences, such as Google’s Material Design, Microsoft’s Fluent Design System and Apple’s Human Interface Guidelines. Their daily concern is to structure, analyze and envision as much clarity, flow and cohesion as possible. Interfaces also have a graphic and visual role, including established branding and elements that complement them. We work with all the colors, shapes and visual materials important to a project, taking its persona into account. Keep in mind that UI Design is concerned with everything that must be structured visually, which also belongs to UX, but from a different perspective.

It is normal for a new UI Designer to start by creating things from scratch, inventing structures and combining colors and shapes to make an interface prettier rather than well-structured and functional. This can be slow and undervalued work. Processes exist to help you reach a result; practicing them creates consistency and a stronger focus on usability. Creating an interface takes considerable work, and without a well-structured process, the project can suffer.

It is worth noting that UI Designers also need to consider possibilities, paths and options for users, something generally associated with UX. UI Design addresses usability as a whole, not just aesthetics. Just as Engineering and Architecture share subjects at university, UI and UX complement one another and collaborate to explore these possibilities, both playing UI and UX roles in the interface.

Here are some tips for establishing standards:

Good Habits for a UI Designer

• Learn to follow processes. Value them from beginning to end.
• Draw from several sources of information, but focus on standards.
• Prioritize researching structures that already work.
• Review structures and name frames. Checklists can help.
• Focus on a good prototype and usability testing. They will guide your path and show where you are heading.
• Organize your file. It may seem trivial, but it helps you see information clearly when making decisions.
• Study and practice sound methodologies, including Sprints, Shneiderman’s design principles and Gestalt principles.

The Role of UX

In UX, the work focuses on usability. UX Designers should aim for—and achieve—what would be ideal for users to think. They must anticipate users’ thoughts and be the strategists behind the magic. They consider errors and successes, analyze possibilities, and explore and integrate what may or may not work.

This applies to the flow users will follow, their potential errors and their successes.

Good Habits for a UX Designer

• Document your entire process.
• Prioritize logical flows.
• Run tests—lots of tests.
• Review structures and name frames. Checklists can help.
• Focus on a good prototype and usability testing. They will guide your path and show where you are heading.
• Organize your file. It may seem trivial, but it helps you see information clearly when making decisions.
• Study and practice sound methodologies, including Sprints, Shneiderman’s design principles and Gestalt principles.

The Verdict

It is wonderful to discuss the differences and specializations of both fields. ‘That is UX!’ ‘That is UI!’ Of course, each has its own identity and definitions, and it is entirely possible to work within these specializations throughout a project. But ultimately, when we talk about usability and interfaces, we are talking about both: we integrate them, even if we separate them again later.

As in every field of communication, it is essential to understand what each area means and communicates, and its particular language. When we discuss design, we discuss functionality, purpose, aesthetics and innovation. When we understand that language clearly and apply it effectively, we can achieve meaningful results by drawing on both sources of knowledge. You can identify as a UI Design or UX Design professional, but both disciplines communicate, understand and complement each other. Understanding that relationship is fundamental to being a professional in either field.

UI and UX go hand in hand, but that does not mean they are the same thing.
