Abstract
How human perception and action deal with uncertainty has been extensively studied using the rubber-hand illusion
(RHI), which introduces a sensorimotor conflict by means of a rubber hand, causing a shift in the perceived location
of the real hand. A recent study showed that in addition to the drift in perception, the RHI also evokes an involuntary
force at the hand in the direction of rubber hand. Seemingly congruent to this finding is the strong interdependence
between perception and action found in active inference. In this work we propose a deep active inference agent which
deals with high-dimensional visual inputs in a virtual environment, that is able to account for the action produced by
humans under the RHI. In addition, the agent was subjected to reaching tasks, validating the proper function of the
agent’s perception and action.
