    Things in flux : Understanding the ontological dynamics of digital heritage objects
    (University of the Witwatersrand, Johannesburg, 2024) Coetzee, Anton Stephen; Wintjes, Justine
    Processes of digitisation, particularly within heritage-related fields, are frequently rendered as being infinitely thin and consequently mechanically objective. The lack of engagement with their complexity results in what Latour calls “black boxing” of the processes, technology, and practices. In this work I examine techniques and practices of 3D photogrammetric recording of archaeological, ethnographic and art objects and collections. Using two exemplars in the form of a late 19th century “curio” in the KwaZulu-Natal Museum collection, and a San rock art site near Van Reenen, I unpack and attempt to understand what is contained within these black boxes. I offer digitisation as a thoughtful, object-centric practice rather than data-driven process, drawing on ideas from Caraher’s “slow archaeology” and Stobiecka’s “prosthetic archae- ology”. Objects are decontextualised and unanchored in the process of excavation or procurement, and on accession into collections they are inducted into organisational and taxonomic schemas designed to afford them value as epistemological objects. These schemata are both biased and flawed, being natural heirs of colonial knowledge systems, and are thus lacking in awareness of multiple ontological viewpoints. By reframing the original thing and the resultant digital object in an ontological sense, I attempt to characterise these systems and their constructions of authenticity. I look to past practices of three-dimensional recording and copying, namely plaster casting of specimens and sculpture, and their role in not just practices of duplication, but also in furthering the colonial project and its epistemological flows. Collection, casting and digitisation — as acts of physical and material translation — perpetrate violences involving iii removal of things from their context, remaining adrift until re-anchored within schemata and rules. Understanding and challenging the nature of these rules is critical in avoiding the risk of reinscribing procrustean colonial approaches to recording and documentation. Furthermore, as metadata and data become inextricably entangled, it becomes more diffi- cult to recreate compelling narrative and “human-readable” context from these structures. However, these shortcomings might rather offer potential, building on Lev Manovich’s ideas of database trajectories and Ruth Tringham’s “recombinant histories”, allowing new and unforeseen paths through the data. I suggest that by eschewing neoliberal metric-driven approaches to “mass digitisation” in favour of small-scale, thoughtful practices, we foreground the opportunity to learn from and with the thing during digitisation. Opening up the “black boxes” and exposing and recording craft practices helps reconnect the digital object with the original thing, and offers a reconfigured view on digital authenticity. By formally recording these acts and decisions we can also contribute to the communities of practice which have grown around many of the arcane skills of digitisation.

    Constructing the Afrocyborg in VR 360 Cinema: A Critical Investigation into how Two African Women Filmmakers Collaborate to Construct Prosocial African Science Fiction in Virtual Reality Filmmaking
    (University of the Witwatersrand, Johannesburg, 2023-10) Passchier, Shmerah; Koba, Yolo; Sakota, Tanja
    The Afrocyborg semiotic construct is a neologism inspired by cyborg scholarship, beginning with Donna Haraway’s 1985, A Cyborg Manifesto, which materialised at the zenith of the Third Industrial Revolution (3IR), and the appearance of the domestic personal computer (PC) in the late twentieth century. This contribution to cyborg discourse re-focuses the Western science/fiction gaze of “cyborgology” by foregrounding African cyborg realities at the centre of the new zeitgeist of 4IR-driven XR technologies, specifically the VR HMD as an immersive computing device, which is a cyborg prosthetic extension of human ocular abilities (Gray 1995: 1). Moratiwa Molema and I formed the Afrocyborg VR Collective as an Afro-technofeminist coalition, and solidarity support group for collective womanist filmmaking. This methodology foregrounds the technological empowerment of women in relation to VR as a medium while focusing on prosocial subject matter in the domains of eco-justice and racial-gender-justice (Ogunyemi 2006: 21). For this reason, the Afrocyborg VR Collective make Prosocial VR films in the genre of African Science Fiction, which is a counter-hegemonic narrative lens through which to generate “cyborg consciousness” about “oppositional consciousness” (Sandoval 2020: 408; hooks 1992: 264). Cyborg oppositional consciousness is expressed as “Fourth VR” (Wallis & Ross 2020: 1). An Afro-technofeminist, technopolitical framework advances filmmaking discourse and praxis by autodidactic online learning of how to operate VR equipment, thereby overcoming our tech-inferiority complex with a thought experiment we call the “Dora Milaje mind trick” (Coogler 2018). As we learn, we also teach VR skills to our students and communities of youth to share knowledge of 4IR tools, specifically with women, to empower them with 4IR STEAM skills as a technopolitical, educational and future-proofing empowerment strategy. The Afrocyborg Collective has made two VR films in the genre of Prosocial VR as part of the creative praxis of Quantum Botho/Ubuntu in the making of The Cosmic Egg, which is a call to elevated environmental consciousness, and The Eye of Rre Mutwa, which confronts “white fragility” about the technological developments of the 4IR (DiAngelo 2018). By experimenting with new gaze regimes offered by the exponential medium of VR, with its multiple lenses that create 360-degree spherical story worlds, we demonstrate how the “medium is the muthi” when used in the mode of Prosocial VR. Therefore, the construction of an expanded prosocial gaze in VR, in the genre of African futurism, contributes to the decolonial undoing of oppressive power structures by generating representations of Africa that seek to apprehend the stereotypes of Hegelian racial prejudice and “poverty porn” that persist in global media representations (Kahiu 2017).
