Abstract
This study defined collaborative artistic acts that forge a relationship between life-world and art based on the characteristics and essence of art practices within contemporary art. It clarified the process of generating empathetic dialogue vis-à-vis artistic acts simultaneously made a social interaction. First, this study defined collaborative artistic acts based on eleven contemporary art styles related to artistic acts causing a social interaction. Next, I analyzed the collaborative artistic act of “Leaving traces at the beach” using the definition as the framework for interaction analysis of both the transcript and image fragments. The case analysis revealed that the emergence of larvae from holes in the sand had triggered a social interaction and an empathic dialogue in which humans and larvae coexist with each other.
