Virtual reality (VR)-based education has gradually emerged as a significant trend in future educational development, as VR technology can concretize and visualize various abstract concepts in teaching. Given the importance of evaluating VR educational institutions to promote VR education, this study proposes a multi-attribute group decision-making model that integrates trust networks and three-dimensional emotions within an interval-valued Pythagorean fuzzy set (IVPFS) environment. First, considering the decision-makers’ affective cognition, a three-dimensional emotion model is incorporated into the IVPFS framework. Second, the Beta function is employed to describe changes in the trust relationships pre- and post-decision-making, thereby adjusting the weights of the decision-makers. Furthermore, the extended evidential reasoning (ER) method is utilized to rank and select VR educational institutions. The results indicate that VRSCHOOL (0.6338) outperforms VISTANDARD (0.6214), GROWLIB (0.5834), and STARUR (0.5738). Finally, the robustness and effectiveness of the proposed method are validated through sensitivity and comparative analyses. © The Author(s) under exclusive licence to Taiwan Fuzzy Systems Association 2025.
