🖱️User Interface

NEW

Also known as: UI

User Interface is the point of human–computer interaction comprising visual, auditory, and interactive controls.

DESCRIPTION

User Interface (UI) comprises the layouts, controls, and visual language users manipulate to operate applications and data systems. Effective UI design supports clarity, discoverability, and efficient workflows. In BI and data science tools, UI decisions affect comprehension, filterability, and exploration. Common patterns include forms, tables, charts, and command palettes. UI aligns closely with UX but focuses on tangible elements and interaction states.
