Introduction to Human-Computer Interaction.png

Human-Computer Interaction (HCI) is the study of the interaction between humans and computers and the design of computing technologies. It overlaps user-centered design, user interface design, and user experience design.

In this course, you will take a deep dive into HCI, so you can create designs that provide a fantastic user experience. More specifically, you learn the rules and principles behind the good and bad design as well as how to use design models to build interactive interfaces. In the latter half of the course, you’ll learn how to evaluate different models and how HCI is used in the real world.

Whether you are new to HCI or a professional, by the end of the course you will have a clear understanding of what it means to be a user and how to implement user-centered design for the best possible results.

Introduction to Human-Computer Interaction

## Why do we need to study this chapter?

To understand the interaction between humans and computers, we need to understand the limitations and capabilities of both. Before we design something for humans, we need to know the things humans find difficult or easy to perform and understand. We also need to be aware of the constraints of the system and the functionality available in it.

In this chapter, we first take a look at how humans perceive external stimuli. We then talk about how human memory works, followed by a discussion on our thinking and problem-solving abilities. 

Later in this chapter, we look into the input and output channels of a computer. Then we learn about the limitations of computer memory, such as storage capacity and computational power because we don't want to design an interface that is beyond a computer's processing capability.
