“…Until recently, virtual reality applications have not been used to simulate medical procedure nor conduct medical research to further our understanding of human anatomy and physiology, let alone introduce patientspecific technological capabilities in the world of medicine. Sigitov et al, [3] mention in their work that although most medical professionals use modern threedimensional (3D) imaging equipment like Computed Tomography (CT) and magnetic resonance imaging (MRI) scanners, most of the information reviewed is in a "slice-wise manner" on a "2D medium" which does not give medical professionals the, sometimes, necessary opportunity to immerse themselves nor interact with the data in an informative manner. While some efforts have been made to immerse users in 3D anatomical structures like blood vessels, Long et al, [4] chose only to provide volume rendering to stop depth perception from being lost and disorienting the user.…”

“…Unity 3D is a software created for the development of digital games but, recently, has been used in several field of study including engineering, medical simulation and architecture. Sigitov et al, [3] have used the platform for rapid prototyping and content generation as has been done in this study. Having successfully modeled the hipfemur assembly in SolidWorks, a SimLab Soft FBX file exporter add-on was used to create the appropriate file type for Unity 3D readiness [9].…”

Virtual reality is the future of medical imaging diagnosis. Previous studies have introduced virtual reality rendering of anatomical models while others have mentioned processes to extract 3D models from Computed Tomography (CT) images. In this study, we provide a detailed workflow to transforming patient-specific twodimensional (2D) CT dicom format imaging files to three-dimensional (3D) immersive, dynamic and interactive anatomical assembly models while incorporating them into a four-wall virtual reality environment system. Our study implemented 3D CAD and virtual reality capacities through software and engineering design tools to transform 2D medical images into interactive 3D models in our system. In doing so, the user was able to gain a sense of depth, scale, and dimensionality while immersed in the environment and while implementing interactive tools to investigate patient-specific hip-femur dynamics. At the same time, users were able to identify key anatomical landmarks in the patients' hip joints. Applications of the VR system to the medical field and orthopedics, in particular, were discussed.

“…We implemented two tasks to observe group behavior during collaboration on a wall-sized display. We used the Unity game engine and the Unity plugin for tiled displays (Sigitov et al, 2015 , 2016 ). The tasks were carefully designed based on the sensemaking tasks used by (Andrews et al, 2010 ; Vogt et al, 2011 ; Isenberg et al, 2012 ; Jakobsen and HornbÆk, 2014 ).…”

Large display environments are highly suitable for immersive analytics. They provide enough space for effective co-located collaboration and allow users to immerse themselves in the data. To provide the best setting-in terms of visualization and interaction-for the collaborative analysis of a real-world task, we have to understand the group dynamics during the work on large displays. Among other things, we have to study, what effects different task conditions will have on user behavior. In this paper, we investigated the effects of task conditions on group behavior regarding collaborative coupling and territoriality during co-located collaboration on a wall-sized display. For that, we designed two tasks: a task that resembles the information foraging loop and a task that resembles the connecting facts activity. Both tasks represent essential sub-processes of the sensemaking process in visual analytics and cause distinct space/display usage conditions. The information foraging activity requires the user to work with individual data elements to look into details. Here, the users predominantly occupy only a small portion of the display. In contrast, the connecting facts activity requires the user to work with the entire information space. Therefore, the user has to overview the entire display. We observed 12 groups for an average of 2 h each and gathered qualitative data and quantitative data in the form of surveys, field notes, video recordings, tracking data, and system logs. During data analysis, we focused specifically on participants' collaborative coupling (in particular, collaboration tightness, coupling styles, user roles, and task subdivision strategies) and territorial behavior. Our results both confirm and extend findings from the previous tabletop and wall-sized display studies. We could detect that participants tended to subdivide the task to approach it, in their opinion, in a more effective way, in parallel. We describe the subdivision strategies for both task conditions. We also detected and described multiple user roles, as well as a new coupling style that does not fit in either category: loosely or tightly. Moreover, we could observe a territory type that has not been mentioned previously in research. In our opinion, this territory type can affect the collaboration process of groups with more than two collaborators negatively. Finally, we investigated critical display regions in terms of ergonomics. We could detect that users perceived some regions as less comfortable for long-time work. The findings can be valuable for groupware interface design and development of group behavior models for analytical reasoning and decision making.
