Human-Computer Interaction
Human-computer interaction (HCI) refers to the ways in which users engage with computers and is an important factor that must be considered when designing and developing an application.

Types of User Interaction
Audio allows users to interact with a system using voice commands.
Body movements or gestures (e.g. hand waves or head turns) can control or interact with applications.
Touch allows users to interact by tapping, swiping, dragging or pinching directly on a screen.
Graphical user interfaces (GUIs) provide a visual interface using windows, icons, buttons and menus. Command-line interfaces (CLIs) only allow interaction with the system by typing text commands into a terminal or shell.
