Characteristic evaluation of the audio and visual system of haptic device

This paper illustrates the effectiveness of a proactive data transfer scheme for adaptive display control in a distributed haptic system with virtual reality, which is an application using haptic, audio and visual media. Presentation experiments of an audio-visual stimulus were carried out using a computer graphics of a moving ball and its collision sound. The results obtained show that the sound image at the beginning of an audio-visual presentation is more strongly captured with the visual image than that at the ending, and that the sound image is perceived separately from the visual image even at the timing of the presentation positions of the audio and visual stimuli coincide with each other when the sound source is moving in the collision of the visual image.
