Chapter 4: 3D User Interface Input Hardware

This chapter continues our discussion of the hardware commonly used in 3D UIs. We examine a variety of input devices that are used in both immersive and desktop applications and their effect on 3D UIs. We also examine how to choose input devices for different 3D applications by looking at some important device attributes, taxonomies, and evidence from empirical studies.
