Abstract
This paper explores the challenges of digitizing intangible cultural heritage (ICH) through a focused study of Uilleann pipe performance using motion capture technology. While traditional Irish piping is rich in expressive micro-movements and ornamentation-such as grace notes, triplets, and subtle finger lifts-these nuanced gestures often fall below the detection threshold of standard motion capture systems. Drawing on empirical data collected at the Na Píobairí Uilleann headquarters, this study reflects on both the technical and conceptual issues encountered in translating embodied cultural practices into digital form. Key concerns include magnetic interference, sensor limitations, and the complexity of capturing expressivity that is not always visually pronounced but musically essential. The paper argues that such "ghost data"-the movements that are performed but incompletely captured-highlights broader tensions between the ephemeral nature of ICH and the technological imperative to document, preserve, and replicate. By critically engaging in these challenges, the research contributes to ongoing debates around authenticity, embodiment, and the role of digital tools in safeguarding living traditions.
