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.

Establishing a software hypothesis

Software is a risk because you are solving human problems and, as we have discussed, humans are hard to understand. If you believe you are solving problems correctly, it requires you establishing a question to ask to know whether you have solved the problem. A software hypothesis works like any other hypothesis and becomes a starting place for understanding whether your idea, built into computer software, works. Prototyping, as we have been discussing, is a way to test your hypothesis. As an HCI designer, setting a good hypothesis allows you and your team to focus on what they believe they can achieve.

A hypothesis states the HCI team's predictions about what your software will do for your user, and is a preliminary answer to either a research question or a business problem that a piece of software is hoping to solve but that has not yet been tested. Some software teams will write multiple hypotheses that address different features or assumptions...
