This Ph.D. dissertation presents the Embodied Avatar Performance (EAP) projects, which are grounded in transdisciplinary research that explores the potential of performance art, virtual reality (VR), and interactive technology in connection with Korean healing rituals, in order to foster well-being in the life-review process. This research, in the context of performative and digital media arts, consists of the development of two avatar life-review projects: VoicingElder (2016-2018) and VoicingHan (2018-2020) in the context of Arts and Health. VoicingElder and VoicingHan have been developed together with health professionals as pilot programs in healthcare and wellbeing for older adults in senior residences and for cancer patients in palliative care. The EAP conveys the research processes of these avatar life-review projects that were developed to support playful and emotional engagement of the participants with their memories, exploring a continuous development of the participant’s emotional process as a therapeutic potential. These avatar projects have a transcultural component based on the Korean concept of Han and the traditional healing rituals in Korea. This practice-based research is presented as an article-based thesis that acknowledges transdisciplinary contributions in exploring the potential of digital media art in healthcare as well as diverse technologies such as avatar interactivity, motion capture, emotion AI (a sentiment analysis algorithm), and virtual reality.
