1. Visual comfort device comprising:
at least one inertial sensor configured to obtain inertial information,
at least one screen, the screen for positioning laterally in an outer monocular field of an eye of a user, and
a processing unit coupled to the inertial sensor and to the screen, wherein
the processing unit is configured to:
upon initialization of the device, produce a virtual matrix having a position in space surrounding the user,
compare the inertial information upon initialization of the device to current inertial information to determine a displacement of the virtual matrix relative to its previous position, in a reverse movement to that indicated by said current inertial information, and
extract a portion of the virtual matrix to display on the screen an inertial matrix representative of an image of the extracted portion of the virtual matrix, said displayed inertial matrix containing a maximum of sixteen points and/or line intersections.
