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.

Coding – markup syntax and object-oriented syntax

As we discussed earlier, we are going to use web coding languages as our proxy for talking about the thousands of coding languages. Let's start by discussing markup languages. HTML is a markup coding language. The coding language is designed as a way to annotate a document in its syntax to be called out from the content text. Markup coding languages come from the concept of writing on a paper draft, which is traditionally written on with a red marker by an editor. In digital media, this "markup text" was coded into HTML tags, thanks to Tim Berners Lee and his colleagues. Markup languages such as HTML are the basis for structuring web software. HTML is considered a semantic coding language.

Semantics is the study of language meaning and the interpretation of words, signs, and sentence structure. Reading comprehension is largely determined by semantics as it defines how we understand others, and even what decisions...
