The intertwined and inseparable relation between humans and technology has been a focal point of exploration for decades—evolving from the mechanical age to the digital era. Today, as technological advances permeate nearly every facet of human life, from the everyday to work life, the study of human-technology interaction (HTI) has expanded into a multidisciplinary area of research that combines psychology, design, computer science, informatics, engineering, sociology, and other disciplines as the use and adoption of new technologies increasingly infiltrate every aspect of human existence. This book intends to be a thorough reference for readers who are curious about and need methods and approaches for navigating the complex inter- actions that occur between people and technology in this broad variety of settings. This book's organization and content are described in the introduction that follows, which also provides an overview of the chapters that cover various facets of HTI.
