1. A sensory substitution system, comprising:
a matrix of exciters configured to be worn by a user such that the exciters interact locally with the skin of the user, the matrix of exciters comprising mechanical actuators;
a control circuit configured to control the exciters of the matrix; and
an asynchronous signal source configured to provide the control circuit with an asynchronous signal representative of visual information organized according to a matrix of pixels, the asynchronous signal comprising, for each of the pixels, successive events associated in an asynchronous manner with said pixel,
wherein the matrix of exciters produces a spatial tactile perception diagram representative of the visual information.
