This paper explores the extensions of the human body in interactive artwork environments, which is considered through the postphenomenological framework of Don Ihde’s philosophy of technology. Through this framework this paper builds upon Ihde’s postphenomenology to consider how narrative is formed in interactive spaces through the gestures and behaviours of bodily movement. This work discusses how the body co-creates meaningful experiences by interfacing with a technology and how such experientially reveals what a body is. This paper analyses Dennis Del Favero’s Scenario (2011), a digital interactive and immersive narrative artwork that uses the body to structure and co-create a fictional experience. Within this work a user’s body becomes virtually wired into the immersive world through the performance of their movement. Emphasis within this cinematic experience is thus shifted from the screen to the moving body that is sensed by the technological architecture of the space, revealing a specific relationship between the narrative, body and space of the installation. Using and building upon Ihde’s framework this paper also incorporates original interview material with Del Favero to consider how a body, within an interactive space, becomes a postphenomenological performance.
