Abstract:
International audience ; As part of the CIGALE project (Capture and Interaction with Artistic, Linguistic and Expressive Gestures), supported by the Labex ARTS-H2H, a multi-agent interaction platform has been developed, which triggers different gestural behaviors of a virtual actor who has the capacity for perception-action, within the framework of a kinematic analysis of the movement of a human interactor’s movement.Our research is fundamentally interdisciplinary, intersecting digital interactive art (relationship with a virtual actor in an artistic situation) and linguistics (gesture study and its expressivity). It leads us to confront the approach of computer modeling of interaction gesture by a finite state machine (FSM) which uses, among other things, a kinematic model of motion analysis (digital art) with the study of the spectator’s gesture through the analysis of the rotations of his arms’ joints (gesture study in linguistics) and through an aesthetic analysis. Based upon the study of the videos of the spectators’ interactions with the virtual actor within the artistic installation InterACTE, we will highlight what would favor the emergence and the continuation of a gestural interaction between a human actor and the virtual actor, thus giving the feeling of a "living" improvisation, ie : the gestures of the virtual actor having characteristics close to that of a child would give the spectator the impression of interacting with a childlike entity arousing its empathy; the alternation of an approximate imitation behavior with the idiosyncratic behavior of the virtual actor would give the impression of an imperfect mimetic capacity and of a certain autonomy proper to "living beings"; the emergence of a great variety of singular dialogues during the interaction between the spectator and the virtual actor, would be the manifestation of their improvised characteristic. A new challenge would be to go beyond an FSM and a kinematic approach through dynamic movement modelling and analysis associated with an emergentist model, so as to amplify the improvised gestural interaction between human and virtual actor, and head towards an aesthetics of improvisation. If, according to Alain Berthoz, “What makes the human being original is precisely his ability to avoid the determinism that confines him in a reality intrinsically linked to his needs and sensory tools, through the remarkable ability of his brain to implement the vicarious processes he is provided with, in order to escape reality or his reality”, could it be that these interactive artistic installations with virtual actor are expressions of vicariance?
