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.

Synthesizing data into action

In the previous chapter, we covered eight methods for gathering both qualitative and quantitative data:

Qualitative methods:

  • Observation: The fly-on-the-wall method
  • The moderated observation method
  • The user interviews method
  • User recording: Tracking analysis and the interview method

Quantitative methods:

  • The quantitative survey method
  • The A/B testing method
  • The usability analytics method
  • The accessibility compliance method

Qualitative and quantitative research methods produce data on your user that an HCI designer can work with to synthesize and analyze. The role of synthesizing is essential in evaluating not just the data itself but also the lasting value any dataset can have on a product or the HCI designer's decision making. Synthesis is the opportunity for the HCI designer to be a detective with the data to find patterns, make correlations between ideas, reveal connections between different users and organized themes and trends, uncover holes...
