Enhancement and Communication of Ancient Human Remains through VR: The Case Study of Sexual Dimorphism in the Human Skull

Over the last years, the exponential progress of technology introduced a broader population of researchers and developers to the use of Virtual Reality (VR) devices in numerous contexts, e.g., gaming, simulations, and culture dissemination. Recently, cultural heritage has also been supported by motivational experiences and other improvements designed explicitly for specific users (visitors, researchers, and domain experts). In this context, we propose a protocol within a digital environment, using innovative, non-invasive, and non-destructive methods for the technological enhancement, education, and dissemination of ancient human remains. The presented case study is focused on sexual dimorphism in the human skull; several 3D models are digitally generated from female and male skull references exploiting an algorithmic approach with statistical analysis, e.g., Principal Component Analysis (PCA); then, the models are made available in a virtual environment with a Head Mounted Display (HMD) and can also be interacted with via a touchless approach (hands-free). Tests conducted with segmented populations provided promising results.
