The first volume provided foundational knowledge on human-computer interaction. This book builds on that and addresses the entire development process of user interfaces and selected recent developments. In a clear and scientifically grounded manner, the authors describe the phases and methods that shape user interface engineering. Numerous practical examples and recommendations for action are discussed for all phases: from requirements analysis to prototyping to the evaluation of interactive systems. Increasingly, 3D content is available, and interacting with it presents its own challenges. Therefore, the middle section of the book is dedicated to 3D user interfaces. Essential aspects are covered in a thorough and concise manner, including 3D input and output devices, core tasks, and specialized 3D interaction techniques. Computers are increasingly being integrated into d.
