Influence of Full-Body Vibration Adapted to Foreground Components on High-Level Perception of Reality

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. Whereas the sense of presence is an evaluation index that includes the background information, the sense of verisimilitude focuses on the foreground information. By adding appropriate sensory information related to the foreground or background component, these perceptual realities could be enhanced. Based on this concept, we investigated the effect of vibration information added to the audio-visual content. In this study, vibration information was generated from the sound that included rich information about the contents. We generated nine types of vibration 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 in a scene. Moreover, under that condition, the sense of presence was hardly affected even when the vibration was added to the content. These results suggest that generating more realism is possible by enhancing vibrations if the processing is performed to match the foreground components in the scene.
