Abstract. Evaluating a user interface often means comparing it against a reference, whether theoretical or empirical. To ensure an appropriate comparison, this paper contributes to computational evaluation by creating a large dataset (top 53 websites ranked in 20 categories: N=1060), computing 53 metrics for them (56,180 entries) by applying a principal component analysis to identify standout metrics, and by performing a factorial analysis to derive a reference visual profile for websites within each category. After analysing the correlations between these 53 metrics and performing various rotations, we have been able to reduce the expressiveness of these metrics to seven latent factors: colorfulness, color complexity, analogous color scheme dissimilarity, primary hue, lightness deviation, complementary colors dissimilarity, and structural simplicity. Therefore, positioning a screenshot with respect to the corresponding visual profile can be simplified based on these latent factors. This approach aims to provide a more comprehensive and context-specific understanding of computational evaluation in the realm of graphical user interface design.

Keywords: Computational evaluation, Computational interaction, Factorial Analysis, Graphical User Interfaces, Principal component analysis, Visual design, Visual Profiles.

Abstract. As medical education evolves, traditional training methods face challenges, particularly in Romanian faculties. This research addresses these issues by developing an innovative Virtual Reality (VR) application to enhance medical training across universities. The VR platform offers a risk-free environment for students to interact with medical objects and procedures, providing detailed performance feedback. The study focused on various interaction methods, including hand tracking and VR controllers, involving 39 participants from diverse fields and age groups. Through surveys, usability tests, and interviews, participants assessed multiple aspects of user interactions, comfort, and challenges like motion sickness and physical strain. Feedback on the effectiveness of these interaction methods for biomedical applications was collected, highlighting VR’s potential to deliver a personalized and learning experience.
