As 3D technology becomes available for a wide range of applications, its successful deployment will require well-designed user interfaces (UIs). Specifically, software and hardware developers will need to understand the interaction principles and techniques peculiar to a 3D environment. This understanding, of course, builds on usability experience with 2D UIs. But it also involves new and unique challenges and opportunities. Discussing all relevant aspects of interaction, enhanced by instructive examples and guidelines, 3D User Interfaces comprises a single source for the latest theory and practice of 3D UIs.

Many people already have seen 3D UIs in computer-aided design, radiation therapy, surgical simulation, data visualization, and virtual-reality entertainment. The next generation of computer games, mobile devices, and desktop applications also will feature 3D interaction. The authors of this book, each at the forefront of research and development in the young and dynamic field of 3D UIs, show how to produce usable 3D applications that deliver on their enormous promise.

Coverage includes:

• The psychology and human factors of various 3D interaction tasks
• Different approaches for evaluating 3D UIs
• Results from empirical studies of 3D interaction techniques
• Principles for choosing appropriate input and output devices for 3D systems
• Details and tips on implementing common 3D interaction techniques
• Guidelines for selecting the most effective interaction techniques for common 3D tasks
• Case studies of 3D UIs in real-world applications
