| Abstract;Since the speed of sound is much slower than light, we sometimes hear a sound later than an accompanying light event (eg. thunder and lightning at a far distance). Sugita and Suzuki (2003) reported that our brain coordinates a sound and its accompanying light to be perceived simultaneously within about 20 m distance. In other words, the light accompanied with physically delayed sound is perceived simultaneously with the sound. We varied depth cues (binocular disparity and motion parallax) in a virtual reality environment, and measured the physical delay at which a light and a sound were perceived simultaneously. In results, we did not find sound-light coordination without binocular disparity or motion parallax, but found it with both cues. It is suggested that binocular disparity and motion parallax are effective for sound-light coordination for simultaneity perception of cross-modal event, and they induce perceptual reality in cross-modal space.
