Neuroarchitecture is a field that studies how built environments affect human behavior and cognition. Virtual reality (VR) has become a valuable tool for research in this area, as it allows for the simulation and testing of different architectural environments. However, VR systems provide a limited level of immersion, which can affect the realism of the user experience. This paper presents a novel augmented virtuality system that combines chroma-based segmentation with real-time auralization to improve immersion in neuroarchitecture experiments. The main technological challenges associated with this approach are analyzed and the feasibility of the proposed solution is investigated. Performance tests on visual and acoustic latency, along with user feedback, validate the effectiveness of the system. The proposed solution is portable and can be effectively deployed in a variety of environments without the need for specialized infrastructure. This approach has great potential for bridging the gap between the physical and virtual domains, opening up new possibilities for neuroarchitecture and other fields that require high levels of immersion.
