“…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.

“…There is a trend is to utilize VR in medical education and training (Walsh et al, 2012;Chan et al, 2013;Mathur, 2015;Moro et al, 2017;Bouaoud et al, 2020;López Chávez et al, 2020;Pieterse et al, 2020); Uruthiralingam and Rea (2020) and Duarte et al (2020) provide an overview. The availability of head-mounted displays has sparked some new research (Chen et al, 2015;Choi et al, 2016;Inoue et al, 2016) in addition to already covered fields. Mann et al (2018) present a taxonomy of various related approaches (virtual reality, augmented reality, etc.).…”

3D reconstruction is a challenging current topic in medical research. We perform 3D reconstructions from serial sections stained by immunohistological methods. This paper presents an immersive visualization solution to quality control (QC), inspect, and analyze such reconstructions. QC is essential to establish correct digital processing methodologies. Visual analytics, such as annotation placement, mesh painting, and classification utility, facilitates medical research insights. We propose a visualization in virtual reality (VR) for these purposes. In this manner, we advance the microanatomical research of human bone marrow and spleen. Both 3D reconstructions and original data are available in VR. Data inspection is streamlined by subtle implementation details and general immersion in VR.
