User Interface (UI)
Visual and functional organization of elements users interact with.
Beginner-friendly explanation
The user interface (UI) is the set of visible elements on a website or app: buttons, menus, colors, icons. A good UI makes navigation simple and pleasant.
Example: A big green “Buy” button clearly visible on a trading page is part of the user interface.
Intermediate-level insight
UI relies on visual hierarchy, message clarity, and stylistic consistency. It facilitates user action by making each step intuitive.
Example: On a trading app, consistent icons and coherent colors quickly guide users to main functions.
Advanced perspective
An advanced UI harmonizes aesthetics and performance. It uses perception psychology (Gestalt principles, affordances) to design fluid journeys and engaging micro-interactions.
Example: On TradingView, adapting design to user behaviors (contextual icons, dynamic menus) optimizes visual efficiency without cognitive overload.
