This paper details the participatory design and production of Realidad Helicoide, a virtual reality (VR) experience documenting human rights violations at El Helicoide, a Venezuelan detention and torture center. Originating from the testimony of journalist and former prisoner Víctor Navarro, the project expanded to include the contributions of over 30 survivors. Employing ethical storytelling and immersive narrative techniques, Realidad Helicoide strategically fosters empathy without sensationalizing violence, enabling users to morally witness past and ongoing injustices. The VR experience has engaged international decision-makers, prompting diplomatic and policy actions globally, and was selectively disseminated clandestinely within repressive environments. Its effectiveness underscores VR’s potential in mobilizing stakeholders and advocating for human rights. The paper significantly contributes to discussions on immersive journalism, digital memory preservation, and interactive storytelling, highlighting essential insights into designing emotionally resonant and politically impactful immersive media.
