Table 5.3: Experiment AIIE2: Foreground Occlusions and Reported Presence II
Background Experiment AIE1 found an effect of foreground occlusion on reported presence. However, demand characteristics may have played a role.
Hypothesis Foreground occlusions increase reported presence compared to the same FOV without a foreground occlusion.
Methods The experimenter was naive to the hypothesis. 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 < .04).
Conclusions The results support the prediction that foreground occlusions can increase reported presence.
