    Modelling consciousness using projective geometry

    Résumé : Consciousness is an embodied experience that we model by perspective taking on a real 3D world, common to any subject, through 3D projective geometry. It enables us to define an internal space proper to each of them from which one can naturally discriminate between sources of information making it a global workspace.
    In previous work [1-3], principles of this framework were exhibited and a first mathematical formulation [4] of these principles enabled to explain and model the moon illusion in a much more complete manner than previous explanations, making refutable predictions for example on perceived size of the moon. More recently [5] a mathematical formulation was developed for the conjectured projective nature of consciousness which gives new insights for known psychophysical phenomena. We will present these works and give a glimpse on ongoing developments on how one can generalize these idea and use geometry to define a global worspace an adaptative systems can use for integrating information.
