Learn Human-Computer Interaction

By: Christopher Reid Becker

Overview of this book

Human-Computer Interaction (HCI) is a field of study that researches, designs, and develops software solutions that solve human problems. This book will help you understand various aspects of the software development phase, from planning and data gathering through to the design and development of software solutions. The book guides you through implementing methodologies that will help you build robust software. You will perform data gathering, evaluate user data, and execute data analysis and interpretation techniques. You’ll also understand why human-centered methodologies are successful in software development, and learn how to build effective software solutions through practical research processes. The book will even show you how to translate your human understanding into software solutions through validation methods and rapid prototyping leading to usability testing. Later, you will understand how to use effective storytelling to convey the key aspects of your software to users. Throughout the book, you will learn the key concepts with the help of historical figures, best practices, and references to common challenges faced in the software industry. By the end of this book, you will be well-versed with HCI strategies and methodologies to design effective user interfaces.

Executing usability tests

If you are not user testing to improve the usability of your solutions, you are underserving your users:

Designing and testing software is connected to the idea that we are designing software that needs to be usable. I know I am doing a lot of screaming at you in this chapter. I don't mean to be demonstrative, but I think it is important to get this across. Usability testing your prototypes is part and parcel of user validation. If your idea works for your user, you want to make sure it is also usable. Many before me have established software usability best practices, and they have been established through rigorous user testing outcomes. We discussed usability heuristics and other methods that help a software product be useable. The only way to truly understand if your software is usable is to test it with your users.

Like other forms of user feedback, usability testing is focused on the user's ability to use a UI effectively throughout the execution...
