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

In the lesson [Usability Engineering Lifecycle Model](https://www.educative.io/courses/intro-human-computer-interaction/usability-engineering-lifecycle-model), we introduced you to the concept of contextual task analysis and why it is significant. In this lesson, you will learn a step-by-step technique, which we are calling the sample technique, to perform contextual task analysis on the requirements we gathered from the user profiling technique. 

## Sample technique 
This technique consists of 10 steps, but the whole process can be classified into three stages. These stages are:
* *Gather background information* 
* *Collect and analyze data from contextual observation/interviews*
* *Construct current user task organization model*
