Welcome!You've already learned about design tools. Now, let's explore Human Computer Interface (HCI) and how it impacts our everyday lives.
What is a Human Computer Interface?A Human Computer Interface (HCI) is how people interact with computers and devices. It includes screens, keyboards, touchpads, and voice controls. The goal of HCI is to make communication between humans and machines easier and more efficient.
Why is HCI important?HCI ensures technology is accessible and user-friendly. For example, mobile apps use intuitive interfaces to help users shop, learn, or play games. Poorly designed interfaces can confuse users or make tasks harder.
Which of these is an example of an HCI?
