UI

The interface users see and interact with on a screen.

UI (User Interface) refers to the visual and interactive elements of a product that users engage with, like buttons, menus, icons, forms, and layouts. Whether it’s a mobile app, a website, or a smart assistant, the UI is everything a user sees and touches to navigate and complete tasks.

A good UI is clear, intuitive, and makes it easy for users to do what they need with minimal effort or confusion. It also communicates brand personality through visuals, layout, and tone.

UI works with UX (User Experience) to make digital products feel natural and easy to use.

🧭 What’s the difference between UI and UX? #️⃣

  • UI and UX (User Experience) are closely related but not the same.
  • UI is about the look and feel, colors, typography, buttons, and layout.
  • UX is about the flow and experience—how easy it is for a user to reach their goal.

Think of UI as the steering wheel, pedals, and dashboard in a car, and UX as how it feels to drive it.

📲 Types of UIs #️⃣

There are many types of user interfaces, including:

  • Graphical UIs (GUIs): The most common, involving screens, icons, and visuals.
  • Voice UIs (VUIs): Used in smart assistants like Siri or Alexa.
  • Gesture-based UIs: Found in VR, AR, and motion-controlled devices.
  • Touch UIs: Used on smartphones and tablets.

🌍 UI in localization #️⃣

In localization, UI plays a big role in adapting products for global users. Translated text might be longer or shorter than the original, which can break layouts if the design isn’t flexible. Right-to-left (RTL) languages like Arabic or Hebrew require mirrored layouts. A strong design system with adaptable UI components (like in Figma) helps teams build interfaces that scale well across different languages and cultures.

Localazy helps teams create UIs that stay consistent across different languages. Our Figma plugin simplifies the process by integrating translation directly into design workflows, preventing layout issues caused by text expansion or right-to-left formatting.
