    Maithani, Charu "The Gesturing Screen: Art and screen agency within postmedia assemblages." PhD , University of New South Wales (UNSW), 2021
    Keywords/Fields of Study : screens; gestures; postmedia

    Abstract: This thesis investigates screens as key elements in postmedia assemblages where multiple technical devices and media platforms function relationally to activate new capacities. I characterize the agency of screens as a gesturality that re-arranges and sustains medial relations with and between other components. The gestures of screens reformulate mediality, but also shift experiences and open elements to novel formations and affects. In re-organisation of the postmedial assemblage, the function and relations of screens are not pre-defined but emerge in process. I develop this dynamic conception of screens and assemblages to account for their diverse manifestations in postmedia. Here I employ an agential realist framework found in the work of Karen Barad and draw on the concept of gestures set out by Giorgio Agamben. This research contributes to a new understanding of postmediality in conjunction with a new conception of the agency of screens. By challenging an understanding of screens that limits them to mere casings for images, this thesis expands the scope and role of screens in postmedia art practices. Focusing on mainly digital screen-oriented artworks, the thesis argues that such art works and practices foreground the gesturality of screens, and offers in-depth studies of works by Shilpa Gupta, Ulrike Gabriel, Natalie Bookchin, Blast Theory, Ragnar Kjartansson, Sandra Mujinga and Sondra Perry. Such works highlight how screens come to be relationally enacted in postmedia and how that enactment occurs through their performance of medial gestures. I identify two kinds of gestures of postmedia screens that support and connect the technical, aesthetic and in some cases political components of an assemblage. I turn to the multiplicity of frames both on-screen and distributed across screens observed by theorists of media such as Lev Manovich and Anne Friedberg. But the postmedial frame is consistently accompanied by what is out-of-frame – scrolling, swiping and ‘pinching’ continually calls on the out-of-frame to be moved on-screen. The out-of-frame is a postmedial screen gesture, then, that maintains an ongoing relation to the ‘inside’ of the frame, supporting and conditioning it. The multiple temporalities of postmedia assemblages – such as that of images, participants and software – allow an ‘out-of-frame’ to endure beyond the framed image. The second gesture is observed in the pervasiveness of chroma screens — blue and green screens used for compositing other images in postproduction. I suggest that this now ubiquitous technique suspends images from screens. Through a relational analysis of colour, and focusing on Perry’s work, I draw upon ways in which the blankness of chroma screens can be made to gesture a different enactment of race – ‘blackness’ as productive difference. Such gesture in postmedia entails the circulation and transference of social and cultural setting. These two gestures of screens highlight multiple dimensions of the relations of postmedial screens beyond that of framed images, offering us ways to be attentive to enactments of screens as they continue to gather relevance in our expanded visual setting. As screens multiply, this research suggests alternate ways of conceiving the aesthetics and experience of screens’ persistent medial configurations.
