From: Auditory stimuli degrade visual performance in virtual reality

Figure 2

(A) Spatial layout of the experiments. The three possible locations of the visual targets inside the participant’s FOV: center, and 4\(^{\circ }\) of visual angle to the left and right. The targets subtended a visual angle of 1\(^{\circ }\). Auditory stimuli were spatially located outside the FOV, also in one of three possible locations, all of them 0.2 m (Unity distance) from the user position: behind the participant, 50\(^{\circ }\) left or 50\(^{\circ }\) right. Both the visual targets and the auditory stimuli kept their positions fixed relative to the participant’s head. One possible combination for a biCond stimuli is highlighted in blue. (B) Temporal layout. Visual targets are shown 100 ms after the sound starts, for a duration of 24 ms. The auditory stimulus lasts 400 ms. Gaze behavior is quantitatively analyzed in those 400 ms to study the relationship between the presence of sound and the visual performance degradation effect.
