Introduction to HCI

1. Human, Computer & Interaction

Human

A human has various ways to perceive the world around
Sight
Sound
Feel/Touch
Smell
Taste
In HCI we have to take into consideration every element of the Human — from the way they perceive and interact with the world, to their long history of using computer and technology.

Computer

With mobile devices and augmented reality, HCI is literally everything and everywhere.
AR application and devices quite literally make this entire world into an instance of HCI

Interaction

The most obvious interaction b/w human and computer could be
human interacts with the computer
computer interacts with the human in response
they go back and forth interacting — and that’s a valid view.

We can also think of human interacting with a task through the computer - computer just mediates the interaction.
OR
Human and computer interact with the task together.
Ideally, the motive is to make the interface as invisible as possible so that the user can spend as little time focusing on the interface — and instead focus on the task they’re trying to accomplish.

This is not the way.
Try clicking the ⋯ next to your doc name or using a keyboard shortcut (
CtrlP
) instead.
