ABSTRACT
Current virtual environment (VE) systems can often induce compelling illusions of self-motion in users. In many instances, the effects of visually depicted motion in a VE can be strong enough to create an overwhelming sense of actual self-motion (vection) in physically stationary observers, along with pronounced postural adjustment and/or a strong sense of disequilibrium and, occasionally, motion sickness. Indeed, the ability to generate realistic sensations of self-motion within VEs might be considered an important element in the overall sense of presence (see Chertoff & Schatz, 2014, Chapter 34) imparted by a given system.
