Expert-Based Review and Evaluation of the Gamified Mixed Reality Application From a User Experience Perspective

Abstract

 This paper presents an expert-based review and evaluation of a gamified Mixed Reality (MR) application designed for dental education. The application designed and developed based on proposed theoretical and practical gamified MR frameworks, with the goal of enhancing the learning experience by employing the enhanced ARCS (Attention, Relevance, Confidence, Satisfaction) model with gamification (ARCS+G) to further increase motivation. The evaluation focuses on optimizing the application’s usability and,consequently, improving the user experience (UX). It also emphasizes the iterative process to ensure a user-centered design using rapid application development (RAD). This gamified MR application allows dentistry students to interact with  holographic 3D dental models, providing an immersive and interactive  learning environment integrated with game elements through the use of
 Microsoft HoloLens 2. The evaluation involved 25 experts from various fields including Computer Science, medical and health science, and game development, and was conducted in two rounds. The results from usability tests and UX assessments indicate that the application is effective in enhancing learning engagement, though areas for improvement were  identified, particularly in user interface design and interaction flow. The findings contribute to the growing field of human-computer interaction (HCI) and the application of immersive technologies in education, offering a framework for future developments in gamified MR applications.
