What is it about?

We embedded a model of consciousness in virtual humans in order to simulate the generation of social behaviours through active inference. Projective geometry was pivotal in integrating perspective taking, social appraisal and the induction of affective and epistemic drives. Virtual humans guessed each other's state of mind by simulating the other's perspective and expectations, to predict its behaviour and adapt theirs accordingly.

Why is it important?

Our approach allows us to analyse and simulate how non-verbal integrative cognition as featured in human consciousness plays a causal role in the generation of complex behaviours. It is a step toward the implementation of model-based tools to quantitatively study the determinants of adaptive and maladaptive behaviours through dynamic interactions between virtual and real humans in virtual reality.


We hope that this article will contribute to set the stage for a science of consciousness in which mathematical expressions of the phenomenology of consciousness can be connected to the generation of observable behaviours in a meaningful and predictive manner. It brings forth innovative theoretical principles that could be used to design human-inspired and human-oriented artificial systems (from virtual humans to robots), to generate interactions between humans and machines that should feel as natural as interactions between humans.
