The screen is intended to be positioned laterally in a peripheral field of vision of a user. The processing unit is coupled to the inertial sensor and to the screen. The device is configured to display, on the screen, an inertial matrix representative of an inertial information item, the displayed inertial matrix comprising a maximum of sixteen points and/or line crossings. ## Claims ### Claim 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. ### Claim 2 (depends on 1) Device according to claim 1, containing two screens arranged to be placed in the outer monocular field of each eye of a user, each screen displaying an inertial matrix. ### Claim 3 (depends on 2) Device according to claim 2, in which the inertial matrix displayed on a screen contains at most nine points and/or line intersections. ### Claim 4 (depends on 1) Device according to claim 1, in which the inertial sensor is fixed to the screen and supplies the inertial information to the processing unit; the inertial information being representative of an inertial orientation of said screen. ### Claim 5 (depends on 1) Device according to claim 1, in which the inertial sensor comprises one or more of the types of sensors selected from the following list: one or more accelerometers, gyroscope, inertial reference system, magnetic field detector. ### Claim 6 (depends on 1) Device according to claim 1, also containing a fastener for a vehicle seat and at least one linking arm linking the at least one screen to the fastener such that the screen is placed at the level of one side of the head of a user of the seat, so that the screen is placed in the peripheral visual field of said user. ### Claim 7 (depends on 1) Pair of glasses comprising two sidearms for engaging the ears of a user, and containing at least one device according to claim 1, at least one screen being fastened on one of the sidearms such that the screen is placed laterally in the peripheral visual field of the user. ### Claim 8 (depends on 2) Virtual reality mask comprising a housing to be placed in the visual field of a user and containing at least one main screen placed in the central visual field of a user, and containing a device according to claim 2 and in which the two screens are placed laterally inside the housing such that they are placed in the peripheral visual field of a right eye and a left eye of the user, respectively.
