User Interfaces Overview

User Interfaces Overview

• A user interface (UI) facilitates interaction between users and computer systems.
• Types of user interfaces are categorized into software and hardware interfaces.

Software User Interfaces

• Graphical User Interface (GUI)

  • Comprises interactive visual components like icons, cursors, and buttons.
  • Enhanced by sounds and visual effects (e.g., transparency, drop shadows).
  • Considered more user-friendly compared to command-line interfaces.
  • Examples include operating systems and applications like Windows, Linux, iOS, Word, Excel, and Access.

• Command Line Interface (CLI)

  • Operates via text input to execute operating system functions.
  • Was the primary method of interaction in early computing but is less common today.
  • Still utilized by developers and system/network administrators for tasks not available in GUIs.
  • MS-DOS serves as a classic example of a CLI.

• Menu-driven Interface

  • Displays available commands through menus; users select options to perform actions.
  • Simplifies usage by eliminating the need to memorize command sets.
  • Can become cumbersome if menu levels are extensive, hindering user navigation.
  • Commonly found in ATMs for managing account functions like withdrawals and deposits.

Hardware User Interfaces

• Touch User Interface
  • Operates through screen touch detection, translating gestures (tapping, swiping, pinching) into commands.
  • Intuitive and accessible to users of all ages, promoting ease of interaction.
