Table 4.1: Experiment AIE1: Field-of-View (Reported Presence)

Background	Investigated the effect of FOV on reported presence.
Hypothesis	Reported presence will be higher at wider FOV's.
Methods	16$^{\circ}$, 32$^{\circ}$, and 48$^{\circ}$ FOV's were compared. There were 1-minute pre-exposures to each condition, order counter-balanced, with 2 per-exposure presence ratings recorded.
Results	48$^{\circ}$ FOV produced significantly higher reported presence than the other two conditions. However, about 1/3 of participants did not rate the widest FOV as invoking the highest presence.
Conclusions	The predicted main effect was found. The 1/3 of participants who did not follow this pattern may reflect a foreground occlusion effect at narrow FOV.
