The research in this dissertation is broken into 3 areas: the measurement of presence; effects of foreground occlusions; and simulator sickness. (In the formulation to be introduced in Chapter 3, these three areas correspond respectively to the measurement, manipulation and malformation of selected rest frames.) This chapter summarizes the relevant literature.
Section 2.2 introduces the literature on presence, and suggests why the study of presence may provide a useful (if partial) measure for the quality of an interface. Section 2.3 surveys the literature on psychological measures, in particular as they relate to presence. Section 2.4 reviews effects of foreground occlusions. Finally, Section 2.5 introduces the literature on motion sickness and simulator sickness.
