Corps Morceles


'Corps Morceles' is an interactive immersive 3-D digital video projection environment. The work employs the fragmentation of the human form to evoke the sense of fragmentation and dissociation experienced through contemporary media - especially how we, as individuals and collectives, are mediated through social and network media platforms. It has been observed that social and network (platform) media have led to the progressive fragmentation of society and cultural identity, with many people constructing their world-view, and sense of self, within insular sub-cultural echo-chambers. This is manifest in the fragmentation and polarisation of political and cultural discourse in many societies around the world. The fragmentation of collective (social) identity arguably has its correspondence in the fragmentation of individual identity - a schizoid condition marked by lack of trust in others, our shared realities and our own sense of self.

Jacqes Lacan employed the term 'corps morcele' (fragmented body, or body in pieces), to describe a subject's lack of unity and subsequent sense of anxiety and hysteria. Lacan observed that when hysterical paralysis affects a limb, it does not necessarily correspond to the physiological structure of the nervous system, but rather (re)presents the body as a fragmented 'imaginary anatomy'. Thus the fragmented body, the 'corps morcele', is "revealed at the organic level, in the lines of fragilization that define the anatomy of phantasy, as exhibited in the schizoid and spasmodic symptoms of hysteria". Lacan apprehended the ego existing in a constant state of uncertainty and threat due to this impending sense of fragmentation, manifesting as "images of castration, emasculation, mutilation, dismemberment, dislocation, evisceration, devouring, bursting open of the body". 'Corps Morceles' explores this idea as a respresentation of the shizoid and dissociated contemporary human condition.

'Corps Morceles' employs full body tracking (Microsoft Azure Kinect IR sensor), calculating the physical location and attitude of 'interactor' bodies, to create (invisible) skeletal representations of interactors in the 3D space. Live video of the interactors occupying the installation space is processed, using colour tracking to identify individual body parts of interactors that are mapped (rendered) to their corresponding 'skeletal' element (eg: knee, elbow, head, etc) to create fragmented three dimensional images of the interactors, which are displayed in the video projections around them. The captured video fragments of the interactors' bodyparts are swapped between different joints and between different interactors, such that one interactor may appear to have the head of another. Individual captured bodyparts are also flipped, horizontally or vertically, depending on interactor behaviour. From time to time the system displays 3-D vectors defined by the boundaries of the captured bodyparts, connecting the swapped elements, making explicit how the process is functioning and creating another level of three dimensional geometry within the work that evokes its organisational principles.

'Corps Morceles' was coded in the Processing language (version 4) on a M3 Max Macbook Pro, with the skeleton tracking coded in C# within Unity3D on an Alienware Windows laptop with NVidia graphics card. The software was written by the artist, including the video tracking and skeletal parsing algorithms. Third party libraries were used for video capture (processing.video) and network communications (hypermedia.net) between the Macbook and Windows computers.
