Table 5.1: Experiment AIIE1: Foreground Occlusions and Reported Presence I

Background	Foreground occlusions have been shown to increase reported vection. If presence and vection are closely related, foreground occlusions should also increase reported presence.
Hypothesis	Foreground occlusions increase reported presence compared to the same FOV without a foreground occlusion.
Methods	The same 60$^{\circ}$ FOV was provided in an HMD either with or without a foreground occlusion mounted in front of the screen. Reported presence was assessed with a presence questionnaire following 2.5 minute exposures to each condition.
Results	Reported presence was higher in the foreground occlusion condition (p < .01).
Conclusions	The results support the prediction that foreground occlusions can increase reported presence.
