(Background and Purpose) There has been a heightened interest in realistic contents that provide information and experiences through human sensory organs amid the recent commercialization of 5G technology that enables creation of environment for immersive and real-time experiences. For such experiences, auditory experience, as well as visual experience, is important, and most of the studies thus far have focused on the modes of visual-centered interactions. Thus, the purpose of this study was to analyze actual cases of spatial audio interaction in VR contents so as to propose the possibility and courses for novel modes of interaction made by using the spatial sound, shifting away from conventional modes of visual-centered interaction. (Method) Based on literature review and Norman's model of interaction cycle by phase, we derived the behavioral characteristics of the process of interaction with user, experiencing the VR contents, through Spatial Audio in VR contents. (Results) The cases of Spatial Audio interaction showed the following characteristics. First, it was found that the directional type of Spatial Audio was used to indicate the location of the initial emergence of objets into the world from certain incident or to inform the user, experiencing the VR contents, of the position of storytelling. Second, it was found that the distance sense type of Spatial Audio was used as a method for alerting the user to the narrowing distance between the user himself/herself and the objets, or as a method for inducing certain behaviors according to the variation of the location of the audio and the user. Third, the predictability type of Spatial Audio was found to allow the objects to be predicted only with the sound that objets had in the same way as in virtual reality. Fourth, the attention type of Spatial Audio was short and the intensive led the user to avert the gaze of user instantly. Fifth, the communication type of Spatial Audio allowed the user, experiencing the virtual contents, to stare at the character telling the story or to be engaged in realistic conversation. (Conclusions) In VR contents, spatial audio was found to be an important element of suitable interaction design in developing the interactive tools. VR contents interact with participants who are using VR contents through sensory information similar to that of reality, but have limitation to their application of the existing modes of media interaction occurring on flat displays. This researcher hopes that the characteristics of spatial audio interaction, presented through this study, would help create a basis for designing the course for audio UIs in the period ahead and be utilized for auditory experience in VR contents.
