Human-computer interaction

Human-computer interaction is when humans and computers communicate with each other. For example, when you use a computer, you can type with your keyboard, click with your mouse, and use your voice with a microphone. The computer then uses its software to understand what you said or did, and it can do something in response. For example, if you type in a website address, the computer will open the website in your browser. or if you tell your computer to print a document, it can do that. Human-computer interaction helps us use computers faster and more efficiently.
