Poetic destructions of apparatus are no longer visible as regimes of apparatus have become transparent: when we press a tactile screen, we touch what we cannot see anymore – our fingerprints – and we see what we will never be able to touch – the digital space. For contemporary artists, haptic interfaces are the finger-tipping point of a technological dynamics of percussion but also the parergon of a new and entirely tactile scale. From the first typewriters to the latest ultra thin keyboards designed by computer manufacturers, we may think imagination is yielding under the ergonomic pressure of the cybernetic world. But in fact, existing outside of the shapes and right under our fingertips lies a palpable reality – the space of calluses. This transfer, this sensory feedback, this return of the form to its structure turns this casting off of the apparatus into an essential isolate to rethink sculpture in the age of immateriality. Right in front of the computer surface but working against it, there would be a functional sensitive thickness – an art-making place. This is our thesis. The machine-like behaviour of the interface user will be considered as a poietic model or regarded as a part of imagination waiting for plastic translation.We may wonder whether the rhythmic experience of interactivity does not entail a perceptual bodily effort on our side in order not to remain absent during the performance of a somewhat predictable photo-digital score.Doesn't this peculiar, callous and rustling – or dactylo-phonic – anchoring of the body to the substance of the world need to express itself? Without this expression, contemporary technological design — whether bi or tri-dimensional, modeled or computer-assisted — will never initiate a truly efficient relation with the real experience of our habits and actions, i.e. with all the embodied strength of our image-making consciousness: does the loss of indiciality create an introverted type of phenomenality ?
