Title: Subjective Evaluation on the Sense of “Being There” using Augmented reality Room Acoustic Estimator (ARAE) Platform.
Abstract: This paper presents a subjective evaluation of spatial acoustic rendering in audio augmented reality (AAR) using the Augmented reality Room Acoustic Estimator (ARAE) platform. AAR aims to enhance user experiences by overlaying spatially and contextually appropriate sounds in real-world environments, creating the illusion that virtual sounds exist within the physical space. However, the current limitations in hardware and algorithms for AAR rendering present challenges in achieving a truly immersive “being there” sensation. The research paper performs a comparative analysis of two commonly used audio delivery algorithms in AAR applications: dummy head recording and stereo panning. These algorithms are evaluated against LiDAR-based spatial acoustics facilitated by ARAE. The main objective is to understand the different impressions induced by each audio algorithm within the acoustic experience of the AAR application and to identify the essential elements that contribute to the sense of “being there.” The results highlight several challenges in ARAE’s acoustic processing, such as inaccuracies in early reflection calculations and localization processing of virtual sounds. To foster a genuine sense of “being there” in the AAR framework, it is crucial to tackle and overcome these challenges through technical advancements and comprehensive psychoacoustic experiments.
