Co-Creation and Digital Identity Construction in Public Art Installations: A Case Study of “MOMO ECHO”

This study investigates the practical transformation of public art installations in the digital era by combining theoretical analysis with a case study of the interactive mechanism and community-generation logic of the “MOMO ECHO” installation. It explores how technology reshapes individual participation, group collaboration, and fluid identity in public space, aiming to reconstruct the contemporary relevance of Roy Ascott’s theories. “MOMO ECHO,” as an interactive installation integrating algorithmic imaging, biometrics, and participatory mechanisms, seeks to visualize these theories and offer a replicable, scalable technological paradigm for the systematic evolution of public art. Through the analysis of 3,820 valid images, this paper employs the anonymity index, personalization dimensions, and feature combination patterns to examine how individuals engage in meaning-making in public space through digital processes that span anonymous generation and collective co-creation.
