To develop advanced multimedia communications systems, understanding how humans perceive reality from the media presented by the systems is important. Various indexes can be used to evaluate the sense of reality. While the sense of presence is an evaluation index that includes background information, the sense of verisimilitude focuses on foreground information. By adding appropriate sensory information related to the foreground or background components, these perceptual realities can be enhanced. Based on this concept, we investigated the effect of vibration information added to audio-visual content. In this study, vibration information was generated from a sound that included rich information about the content. We generated nine vibration types by adjusting the cutoff frequency and the carrier frequency of the sound. The results showed that higher verisimilitude was observed when vibration closely connected to foreground components was added to a scene. Moreover, under this condition, the sense of presence was hardly affected even when the vibration was added to the content. These results suggest that enhancing realism is possible by artificially generating vibrations from sound if the auditory signal is appropriately processed.
