Human-Computer Interaction (HCI) is the interdisciplinary field focused on designing and improving the interfaces between users (humans) and computer technology to enhance usability, accessability and user satisfaction. It integrates elements from media studies, computer science, design, behavioral sciences, and other disciplines. This field is rapidly evolving and is significantly reshaping the way technology is used. HCI draws inspiration from human-to-human communication and seeks to replicate similar design principles in the interaction between humans and computers. This book presents the complex subject of HCI in the most comprehensible and easy to understand language. It outlines the processes and applications of the field in detail. Those in search of information to further their knowledge will be greatly assisted by this book.
