Abstract
In the real world, people use various sensations to perceive the significant information and judge the critical situations and circumstances from the outside, but in the virtual environment the limited sensory information is only provided. What immersive experience the user experiences in the virtual environment depends on how the 3D visual information and the auditory information are combined and provided to the user. Most of the quality factors that determine the immersion feeling of the auditory virtual environment from the viewpoint of the user are the items which are important in the sound design for the conventional two dimensional images. In this study, we measured and evaluated how the relative loudness of ambience sound affecting the spatial feeling and reverberation of auditory virtual environment quality factors are related to user’s immersion feeling when they are adjusted to different forms in two-dimensional and three-dimensional space. The experiment was conducted to determine the amount of ambience sound volume which is most suitable for moving objects and space while observing the same visual information with different two- and three-dimensional displays. As a result, when a three-dimensional event is reproduced in a three-dimensional representation space, an ambience sound with more ambience sound level than a two-dimensional expression space can be provided to the user.
