Abstract
To develop advanced multi-modal displays, it is important that various sensory information is presented with proper amount. Previous studies have pointed out that vibration information enhances participants' immersive experience from virtual display. Therefore, vibration information should be considered when people develop advanced multimedia systems. We have focused on the effect of full-body vibration information to peceived reality. This study examined the relation between full-body vibration amplitude and perceived reality from audio-visual contents. The sense of presence, the sense of verisimilitude, and the sense of ultra-reality were used as indicators of perceived reality. Results revealed that perceived reality increased by adding full-body vibration. Moreover, results showed that the senses of presence and ultra-reality increased monotonically according to the full-body vibration amplitude, while the sense of verisimilitude exhibited a saturating curvilinear tendency. These results suggest that body vibration is important to increase perceived reality from multi-modal contents presented by advanced multi-modal displays.
