3D User Interfaces: Theory and Practice

Part IV. Designing and Developing 3D User Interfaces

Thus far, we have focused on the low-level components of 3D UIs—input/output devices and interaction techniques. Through the guidelines presented in each chapter, we have shown you how to choose devices and techniques for your application that match its requirements and that will result in high levels of usability.

But how do you put all of these components together? What do complete 3D UIs look like? How do you verify that your system is easy to use and efficient? The answers to these questions are the focus of Part IV.

We recommend a usability engineering process (Gabbard et al. 1999) when constructing 3D UIs. This type of process begins with requirements gathering—an analysis of the existing ...
