Abstract
IEEE VR 2020 Immersive audio-visual perception relies on the spatial integration of both
auditory and visual information which are heterogeneous sensing modalities with
different fields of reception and spatial resolution. This study investigates
the perceived coherence of audiovisual object events presented either centrally
or peripherally with horizontally aligned/misaligned sound. Various object
events were selected to represent three acoustic feature classes. Subjective
test results in a simulated virtual environment from 18 participants indicate a
wider capture region in the periphery, with an outward bias favoring more
lateral sounds. Centered stimulus results support previous findings for simpler
scenes.
