Area II: Presence Manipulations

The experiments of Chapter 5 measured the effect of a foreground occlusion on reported presence and on control reversals in an inside-out display. A foreground occlusion is defined in this dissertation as ``an obstruction mounted in front of a display in such a way that only the display (and not its boundary) is visible through the obstruction, and such that the display is at a greater visual distance than all other available visual cues.'' This is diagramed in Figure 2.1 on page .

The experiments of Chapter 5 compared conditions with and without a foreground occlusion, keeping the FOV constant across conditions.
