“…While the method achieves impressive accuracy for static objects, the accuracy drops when scanning a real human. Bauer et al [13] propose an anatomic mirror. The length of the bones are estimated from an RGB-D sequence and used to register an anatomical model.…”

Fig. 1. The Virtual Caliper. A novice user takes 3D measurements of her body using the wand controllers of the HTC Vive in just under 5 minutes by following simple instructional videos. Additionally, the user is asked to enter her weight and gender. The Virtual Caliper immediately produces a rigged 3D model with exactly the dimensions of the measured person. The rigged 3D model can be used straight away in Unity or exported for use in other 3D modeling packages. We illustrate a virtual mirror application where the user can look down and experience her body in VR.

“…Anatomical and Biological Education and Edutainment : Preim and Saalfeld [PS18] presented a survey on virtual anatomy education systems, where they review a big corpus of techniques targeting the education of medical students. These span from surface and volume visualization [PHP * 01,LSHL16,VGHN08] to animations [BPC * 14], and from anatomical labeling [BG05] to virtual and augmented reality [SSPOJ16,PPS19,JPC * 16,MWDE * 16]. Popular examples include VOXEL‐MAN [PHP * 01] and open anatomy browser [HDK17].…”

In this paper, we present a new workflow for the computer‐aided generation of physicalizations, addressing Nested configurations in anatomical and biological structures. Physicalizations are an important component of anatomical and biological education and edutainment. However, existing approaches have mainly revolved around creating data sculptures through digital fabrication. Only a few recent works proposed computer‐aided pipelines for generating sculptures, such as papercrafts, with affordable and readily available materials. Papercraft generation remains a Challenging topic by itself. Yet, anatomical and biological applications pose additional Challenges, such as reconstruction complexity and insufficiency to account for multiple, Nested structures—often present in anatomical and biological structures. Our workflow comprises the following steps: (i) define the Nested configuration of the model and detect its levels, (ii) calculate the viewpoint that provides optimal, unobstructed views on inner levels, (iii) perform cuts on the outer levels to reveal the inner ones based on the viewpoint selection, (iv) estimate the stability of the cut papercraft to ensure a reliable outcome, (v) generate textures at each level, as a smart visibility mechanism that provides additional information on the inner structures, and (vi) unfold each textured mesh guaranteeing reconstruction. Our novel approach exploits the interactivity of Nested papercraft models for edutainment purposes.

Students in undergraduate premedical anatomy courses may experience suboptimal and superficial learning experiences due to large class sizes, passive lecture styles, and difficultto-master concepts. This study introduces an innovative, hands-on activity for human musculoskeletal system education with the aim of improving students' level of engagement and knowledge retention. In this study, a collaborative learning intervention using the REFLECT (augmented reality for learning clinical anatomy) system is presented. The system uses the augmented reality magic mirror paradigm to superimpose anatomical visualizations over the user's body in a large display, creating the impression that she sees the relevant anatomic illustrations inside her own body. The efficacy of this proposed system was evaluated in a large-scale controlled study, using a team-based muscle painting activity among undergraduate premedical students (n = 288) at the Johns Hopkins University. The baseline knowledge and post-intervention knowledge of the students were measured before and after the painting activity according to their assigned groups in the study. The results from knowledge tests and additional collected data demonstrate that the proposed interactive system enhanced learning of the musculoskeletal system with improved knowledge retention (F (10,133) = 3.14, P < 0.001), increased time on task (F (1,275) = 5.70, P < 0.01), and a high level of engagement (F (9,273) = 8.28, P < 0.0001). The proposed REFLECT system will be of benefit as a complementary anatomy learning tool for students.Anat Sci Educ 12: 599-609.
