|Background||Investigated the effect of FOV on reported presence.|
|Hypothesis||Reported presence will be higher at wider FOV's.|
|Methods||16, 32, and 48 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 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.|
