Introduction to Human and Computer Capabilities

Learn why we need to study human and computer capabilities and get introduced to these capabilities.

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.
