"Digital Healthcare: a multidisciplinary and comprehensive vision" is a novel and unique book covering the main topics of health innovation focused on what computer science and technology have been applied in healthcare and what are the perspectives for the future. This is a thought-provoking theme, covering a broad range of aspects of issues, from basic concepts that composes the known "4th industrial revolution" (artificial intelligence, computer systems, big data, internet of things, robotics), all of which has been used in different healthcare sectors, to more recent technologies applied to healthcare, such as smartphone applications, remote consulting, augmented reality, gamification, and brain-machine interactions. All chapters cover detailed explanations of different technologies and how the possible uses in healthcare are, in different contexts, with a multidisciplinary approach, including the vision of technology, health and social sciences researchers. Law, data protection, psychological and ethics issues are also discussed. The great difference of this book is the coverage of updated topics, with the most advanced knowledge of all the technologies described in each chapter, covering several innovations in healthcare, and the multidisciplinary approach, making the book accessible to researchers from different fields of knowledge. The book is divided into sections: 1-Health systems and technology; 2-Tools, devices and other inventions to subsidize healthcare and make patients' lives easier; 3-Artificial intelligence, human-machine interaction, and robotics applied to healthcare; 4-Social sciences, humanities and the ethics that involve the intersection between technology and health; 5-Future health; which interconnects each chapter, making a logical sequence for learning.
