The Effect of Sound on Visual Fidelity Perception in Stereoscopic 3-D

Abstract

Visual and auditory cues are important facilitators of user engagement in virtual environments and video games. Prior research supports the notion that our perception of visual fidelity (quality) is influenced by auditory stimuli. Understanding exactly how our perception of visual fidelity changes in the presence of multimodal stimuli can potentially impact the design of virtual environments, thus creating more engaging virtual worlds and scenarios. Stereoscopic 3-D display technology provides the users with additional visual information (depth into and out of the screen plane). There have been relatively few studies that have investigated the impact that auditory stimuli have on our perception of visual fidelity in the presence of stereoscopic 3-D. Building on previous work, we examine the effect of auditory stimuli on our perception of visual fidelity within a stereoscopic 3-D environment.
