User interface design shapes an application's visible and interactive elements. Zensations in Vienna develops layouts, components and interaction states. UI builds on user journeys and requirements, while UX considers the whole experience.
An interface needs to show which information matters and which action is available next. Typography, spacing and grouping provide orientation. Primary actions should be distinguishable from supporting functions. Long labels and real content belong in the design so the interface works beyond ideally short sample text.
Forms and components need states for input, processing, success and failure. Helpful errors explain what can be corrected. Keyboard focus and contrast support accessible operation. Interactive prototypes reveal transitions before implementation, exposing missing feedback that static screen designs cannot demonstrate.
Reusable components and documented rules support consistent development. Handover describes variations and behaviour across screen sizes. Collaboration with developers identifies technical limits early. The implemented interface still needs assessment because design specifications alone do not guarantee a functioning experience.
