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.

The human side of data collection

Qualitative data is collected through methods of observations and gathers data that can be observed and recorded. Qualitative information data is non-numerical. HCI and UX tend to focus on qualitative research methods at first, especially if the software design team is designing something new. Qualitative data can help a group gather deep understandings of the motivations, problems, and past experiences of our users through observations and interviews.

Take the following example.

We are creating a high school band members' app:

  • User data = 45 students in the user research group
  • Version 1: Qualitative data set by band role:
  • 6 flutes
  • 7 trumpets
  • 12 drumlines
  • 3 tubas
  • 8 saxophones
  • 9 flag guards
  • Version 2: Qualitative data set by student grade:
  • 12 seniors
  • 20 juniors
  • 7 sophomores
  • 6 freshman

The condition creates a quantity but can also associate a set of unique needs from that cross-section of the data. As an HCI designer or user researcher, a team...
