SITh.XRaedo is an immersive XR grief therapy platform developed by VHEX Lab. It creates a virtual avatar of a deceased loved one from a photo, which is controlled live by an XR therapist through an HMD and PC-based interface. In a safe space, the avatar communicates through speech, nods, smiles, and emotional gestures, helping grieving families express unsolved emotion and find closure. On June 25, 2025, in a broadcast news report, Seoneul met her younger sister Hwisu, who died in a tragic airplane crash at Muan Airport, through SITh.XRaedo. In their special space, Seoneul finally said goodbye. So far, SITh.XRaedo has helped twelve families cope with unexpected loss. It offers a therapeutic, human-centered alternative to traditional mourning rituals, combining virtual presence with self-insight therapy. This innovation opens a new frontier in digital health, mental wellness, and compassionate AI. XR / Digital Health / AI-Driven Avatar / Content & Entertainment / Digital Transforms
