User interface

A user interface is part of the computer frontend and refers to the visual and interactive Interface:interface between a user and a software application. It allows the user to interact with the application and control its functions.

Requirements for user interfaces

A good user interface is characterised by several factors:

  • Intuitive and easy to understand usability.
  • Appealing design.
  • Clear structuring and navigation.
  • Consistent design of buttons and menus.
  • Appropriate size and placement of controls.
  • Fast response time to user interactions.
  • Accessibility for people with different abilities or disabilities.

A good user interface contributes significantly to the user experience (UX) and can thus influence the success of an application.
