Designing Mosque Interiors with Virtual Reality: Enhancing Spiritual Ambiance and User Experience Recognizing the challenges in designing mosque interiors that fully capture the spiritual essence while accommodating diverse worshipper needs, this research investigates the integration of Virtual Reality (VR) technology into mosque interior design, aiming to enhance the user experience by focusing on accessibility, comfort, and spiritual ambiance. The primary objective is to evaluate how VR can aid in optimizing physical mosque interiors, using a user-centered approach to better meet the needs of diverse worshippers. The study begins with a thorough literature review on the use of VR in architectural design, particularly in religious settings. A diverse group of worshippers, including individuals from various age groups, physical capabilities, and cultural backgrounds, will be selected to interact with virtual models of mosque interiors through VR. Their experiences and feedback will be systematically gathered using structured questionnaires, focus groups, and interviews. While the initial focus is on improving physical mosque designs using VR, the study also acknowledges the potential of VR to transcend the limitations of the physical world. The idea of creating the next generation of religious spaces in VR is explored, where traditional constraints are removed, allowing for the ultimate spiritual experience. Although current technology limits the ability to perform physical acts of worship like prayer, the research suggests a future direction where HMD (Head-Mounted Display) technology could evolve into contact lenses, enabling worshippers who cannot physically attend mosques to engage in spiritual practices within a virtual environment. The study aims to provide actionable insights and design guidelines for mosque architects, designers, and VR developers. By analyzing how VR can enhance the spiritual atmosphere, accessibility, and comfort of mosque interiors, the research proposes that VR can play a critical role in developing user-centered, spiritually resonant mosque designs both in the physical and virtual realms. The findings are expected to contribute to the architectural field by highlighting the potential of VR to create more inclusive and spiritually enriching religious spaces in the future.
