Evaluation and comparison of novel music experiences in augmented reality
* Presenting author
This paper evaluates and compares different ways of presenting and experiencing music in six degrees of freedom (6DoF) augmented reality (AR). A musical work specifically composed and arranged for 6DoF AR consumption was presented to users in three ways; as a stereo downmix from virtual loudspeakers, as audio objects and as interactive (movable) audio objects. The audio objects and virtual loudspeakers were visualized as icons in the AR scene to help the user to move and interact with the objects. A qualitative and quantitative evaluation was conducted with 12 participants to evaluate the quality of each presentation and experiencing technique. The participants found the experiences with audio objects to be most innovative and most captivating. There was a clearly bigger effort and higher mental demand in accomplishing tasks with the interactive audio objects when compared to the virtual loudspeakers. Both of the audio object experiences were found to be more natural compared to the virtual loudspeaker experience. The overall results indicate that generation of rich and specifically tailored content for new realities is valuable and was perceived well by the users.
