Influence of visual depth and vibration on the high-level perception of reality in 3D contents

This study investigated the influence of stereoscopic visual depth and body vibration on the high-level affective perception that concerns the senses of presence and verisimilitude. The multisensory content used in our experiment consisted of the 3D video recording of a passing train as seen from the side of the railroad, binaural recording of the 3D spatial sound, and the ground vibrations caused by the train. The results showed that the augmented stereoscopic depth information enhanced the affective perception of both the presence and verisimilitude. Moreover, both the presence and verisimilitude saturated with an increase in the intensity of body vibration under the augmented perceived depth condition. However, compared to the presence, the verisimilitude tended to saturate at a lower vibration-intensity. This tendency is consistent with that reported in our previous research.
