The Sense of Auditory Presence in a Choir for Virtual Reality

This paper investigates which auditory parameters influence the sense of presence in an immersive environment of children with low functioning autism (LFA) and social anxiety. The auditory parameters investigated were Spatialized, Authoritarian (e.g. the ability to hear a conductor) and Ambisonic. A 360-degree video of the Danish National Children’s choir shown in the VE enables the participants to sing and dance together with them, while simultaneously being exposed to the different parameters. We discuss how the different audio parameters affect the plausibility of the environment to children. While asking questions in relation to presence, the four participating children were having difficulties grasping the meaning, even when adjusted to their preference and level of understanding. However, the observational data yielded a change in their behaviour and participation with the virtual choir, while differentiating with the changing parameters. This could indicate that presence through auditory stimuli can be observed through the behavioural patterns of children with LFA and social anxiety.
