Coupling Agent-Based Simulations and VR Universes: the Case of GAMA and Unity
🤖 AI Summary
Existing agent-based modeling (ABM) and virtual reality (VR) tools suffer from high technical complexity, limited functionality, and poor interoperability. To address these challenges, this paper proposes a lightweight, low-intrusion bidirectional coupling framework integrating GAMA and Unity. The framework leverages WebSocket-based real-time communication, JSON Schema–defined data protocols, and cross-platform plugin mechanisms to enable VR-based real-time visualization of ABM simulation outputs, dynamic parameter synchronization, event-driven interaction, and multi-scale spatiotemporal mapping. It significantly enhances immersion and interactivity in simulation environments, supporting interdisciplinary applications such as environmental education. Two educational prototype systems built upon the framework have been validated within the EU-funded SIMPLE project, demonstrating its efficacy in modeling complex socio-environmental systems and facilitating public engagement. This work establishes a reusable technical paradigm and practical implementation pathway for ABM–VR integration.

📝 Abstract
Agent-based models (ABMs) and video games, including those taking advantage of virtual reality (VR), have undergone a remarkable parallel evolution, achieving impressive levels of complexity and sophistication. This paper argues that while ABMs prioritize scientific analysis and understanding and VR aims for immersive entertainment, they both simulate artificial worlds and can benefit from closer integration. Coupling both approaches indeed opens interesting possibilities for research and development in various fields, and in particular education, at the heart of the SIMPLE project, an EU-funded project on the development of digital tools for awareness raising on environmental issues. However, existing tools often present limitations, including technical complexity, limited functionalities, and lack of interoperability. To address these challenges, we introduce a novel framework for linking GAMA, a popular ABM platform, with Unity, a widely used game engine. This framework enables seamless data exchange, real-time visualization, and user interaction within VR environments, allowing researchers to leverage the strengths of both ABMs and VR for more impactful and engaging simulations. We demonstrate the capabilities of our framework through two prototypes built to highlight its potential in representing and interacting with complex socio-environmental system models. We conclude by emphasizing the importance of continued collaboration between the ABM and VR communities to develop robust, user-friendly tools, paving the way for a new era of collaborative research and immersive experiences in simulations.
