We survey the state of the art of spatial interfaces for 3D visualization. Interaction techniques are crucial to data visualization processes and the visualization research community has been calling for more research on interaction for years. Yet, research papers focusing on interaction techniques, in particular for 3D visualization purposes, are not always published in visualization venues, sometimes making it challenging to synthesize the latest interaction and visualization results. We therefore introduce a taxonomy of interaction technique for 3D visualization. The taxonomy is organized along two axes: the primary source of input on the one hand and the visualization task they support on the other hand. Surveying the state of the art allows us to highlight specific challenges and missed opportunities for research in 3D visualization. In particular, we call for additional research in: (1) controlling 3D visualization widgets to help scientists better understand their data, (2) 3D interaction techniques for dissemination, which are under‐explored yet show great promise for helping museum and science centers in their mission to share recent knowledge, and (3) developing new measures that move beyond traditional time and errors metrics for evaluating visualizations that include spatial interaction.

Immersive and interactive virtual reality to improve learning and retention of neuroanatomy in medical students: a randomized controlled study

et al. 2018

Background: Spatial 3-dimensional understanding of the brain is essential to learning neuroanatomy, and 3-dimensional learning techniques have been proposed as tools to enhance neuroanatomy training. The aim of this study was to examine the impact of immersive virtual-reality neuroanatomy training and compare it to traditional paper-based methods. Methods:In this randomized controlled study, participants consisted of first-or second-year medical students from the University of Saskatchewan recruited via email and posters displayed throughout the medical school. Participants were randomly assigned to the virtual-reality group or the paper-based group and studied the spatial relations between neural structures for 12 minutes after performing a neuroanatomy baseline test, with both test and control questions. A postintervention test was administered immediately after the study period and 5-9 days later. Satisfaction measures were obtained. Results:Of the 66 participants randomly assigned to the study groups, 64 were included in the final analysis, 31 in the virtual-reality group and 33 in the paper-based group. The 2 groups performed comparably on the baseline questions and showed significant performance improvement on the test questions following study. There were no significant differences between groups for the control questions, the postintervention test questions or the 7-day postintervention test questions. Satisfaction survey results indicated that neurophobia was decreased. Interpretation:Results from this study provide evidence that training in neuroanatomy in an immersive and interactive virtual-reality environment may be an effective neuroanatomy learning tool that warrants further study. They also suggest that integration of virtualreality into neuroanatomy training may improve knowledge retention, increase study motivation and decrease neurophobia.

“…Explicit geometrical model reconstruction from various imaging modalities has attracted considerable interests in the literatures. Geometrical augmentation was proposed in a Virtual Reality scheme for surgical planning (3) and other medical applications (4) , such as interactive colonoscopy system (5) . More recently, physical modeling was also incorporated into 3D synthetic object to improve realistic sense during medical training.…”

This paper discusses interactive 3D reconstruction of ultrasonography model. The proposed scheme can be divided into three modules, consisting of Image Segmentation, 3D Model Reconstruction and Interactive Model Editing.More specifically, a set of 2D radial scans acquired from ultrasonography were segmented using Active Contour, resulting in an unorganized set of 3D points delineating an object of interest on multi-planar images. These points were subsequently fitted with a 3D surface model by an expansion of Spherical Harmonics. As accurately segmenting ultrasound images with low SNR can be challenging, this fitted model will be later interactively adjusted to be more properly coincided with underlying structure subject to expert's opinion. The contribution of this paper is therefore the algorithm and the organizing of related data structure which lend to responsive rendition of the parametric surface being edited.
