“…The stereoscopic view and free viewpoint move-ment can help realize the 3D assessment of sound propagation. We developed two types of sound field visualization systems using different STHMDs and technologies for AR/MR and then created a 3D sound intensity map as a visualization target for sound information [16,17]. We also verified the effectiveness of the proposed visualization systems.…”

For the visualization of a sound field, a widely used method is the superimposition of the sound information onto a camera view. Although it effectively enables the understanding the relationship between space and sound, a planar display cannot resolve depth information in a straightforward manner. In contrast, a see-through head-mounted display (STHMD) is capable of representing three-dimensional (3D) vision and natural augmented reality (AR) or mixed reality (MR). In this paper, we propose a system for the measurement and visualization of a sound field with an STHMD. We created two visualization systems using different types of STHMDs and technologies for realizing AR/MR and a measurement system for a 3D sound intensity map, which can be used together with the visualization system. Through three visualization experiments, we empirically found that the stereoscopic viewing and the convenient viewpoint movement associated with the STHMD enables understanding of the sound field in a short time.

“…Advances in AR headsets create opportunities to present the environment to users in new and novel ways. Much research in this area focuses on using headset displays to visualize parts of the environment not normally seen, such as the visualization of sound fields [10] or visualizations for spatially locating sound [11]. Less research exists on presenting local environmental information (such as spatial mapping data) using audio.…”

We compared four audio-based radar metaphors for providing directional stimuli to users of AR headsets. The metaphors are clock face, compass, white noise, and scale. Each metaphor, or method, signals the movement of a virtual arm in a radar sweep. In a user study, statistically significant differences were observed for accuracy and response time. Beat-based methods (clock face, compass) elicited responses biased to the left of the stimulus location, and non-beat-based methods (white noise, scale) produced responses biased to the right of the stimulus location. The beat methods were more accurate than the non-beat methods. However, the non-beat methods elicited quicker responses. We also discuss how response accuracy varies along the radar sweep between methods. These observations contribute design insights for non-verbal, nonvisual directional prompting.
