An Approach for Studying the Effect of High-Level Spatial Properties of 3D Audio in Interactive Systems

In this paper we briefly describe an approach for understanding the psychoacoustic and perceptual effects of what we have identified as the high-level spatial properties of 3D audio. The necessity of this study is firstly presented within the context of interactive applications such as Virtual Reality and Human Computer Interfaces. As a result of the bibliographic research in the field we identified the main potential functions of 3D audio spatial stimulation in interactive applications beyond traditional sound spatialization. In the same sense, a classification of the high-level aspects involved in spatial audio stimulation is proposed and explained. Immediately, the case of study, the experimental methodology and the framework are described. Finally, we present the expected results as well as their usefulness within the context of a larger project.
