Development and Evaluation of a 3D Human Body Visualization Tool Using HoloLens 2 for Medical Education at the University of Liège

Abstract

This thesis presents the development and evaluation of a 3D human body visualization tool utilizing HoloLens 2 technology for medical education at the University of Liège. The primary objective was to assess the effectiveness of this mixed reality (MR) technology in enhancing the visualization, comprehension, and manipulation of anatomical structures, specifically in the context of medical education.

The research began with the adaptation of a pre-existing augmented reality (AR) application, originally designed for smartphones, which allowed users to explore a 3D model of the human body. The application was modified to function on the HoloLens 2 platform, emphasizing interactive and immersive learning experiences

A qualitative research methodology was employed to gather insights from medical students at various stages of their education. The study was divided into two phases: the first phase focused on evaluating the general experience with the HoloLens 2 application, and the second phase involved a comparison with the existing mobile AR anatomy application. Students provided feedback on usability, engagement, and the educational value of the tool.

The findings showed that HoloLens 2 greatly improved students' ability to visualize and understand spatial relationships in anatomy, especially in complex areas like vascularization and innervation. The intuitive interface enabled quick adaptation, despite initial calibration and gesture challenges. While the immersive experience boosted engagement, there was some concern that the technology might be seen more as a novelty than a serious educational tool.

The feasibility of implementing the HoloLens 2 as a regular tool in medical education was also analyzed through a SWOT analysis. The strengths of the technology include its intuitive user interface, the ability to visualize complex anatomical relationships in 3D, and the enhanced engagement it provides to students. The weaknesses identified include limitations in user experience, hardware, resources, and environment, and the financial cost associated with the technology. Opportunities for the HoloLens 2 include its potential to revolutionize medical education by providing a more interactive and immersive learning environment, and the possibility of its use in remote learning scenarios. However, there are also threats, such as direct and indirect competitors and the uncertain future of the HoloLens technology itself.

In conclusion, the HoloLens 2 shows great promise as a transformative tool for medical education, offering enhanced visualization and engagement through its advanced MR capabilities. However, to fully realize its potential, further refinement of the technology and careful consideration of its integration into existing curricula are necessary. The SWOT analysis suggests that while there are challenges to adoption, the opportunities for improving medical education are significant.
