What is meant by User Interface (UI)?

User interface is the means or medium of interaction of the user with a software application or website or any device. U

The user interface is directly related to the appearance of the application, how the user sees it, and what information can be inferred from the interface. For user satisfaction, the user interface of the application or website or any other kind of software product must be easy to understand, to use, and should invoke the user’s interest in the product. 

User interface should attract the user to make use of the product. The user experience should be effortless and entertaining. A user’s comfort should be prioritized while designing the UI.

Types of User Interface 

  • Form-based user interface: This asks the user to enter required data into fields or options. For example: an online application for school, or login page for any kind of online account. 
  • Graphical user interface: User engages through visual indicators. GUI displays objects on a software page. The visual appearance is directly linked to the graphical user interface. 
  • Menu-driven user interface: Display menu containing dialogue boxes of specific information for the user to choose from. Example: ATM machine UI.
  • Touch user interface: Where the interaction takes place through the user’s touch. Examples: Touch screen of mobile phones. 
  • Voice user interface: Interaction through voice command. Example: Google Assistant, Amazon Alexa, etc.  

Responsibilities of a UI designer

Characteristics of a good UI
