1. A method for determining at least one state of a user in a motor-vehicle passenger compartment, regarding whether is the user is actively driving the vehicle or not,
with an eye-movement sensor device for sensing eye movements of the user, the method comprising:
updating an artificial intelligence with eye-movement frequency data generated by the sensor device for the user, with an eye-movement frequency above a first threshold being characteristic of the user viewing a landscape passing by, and being distinguishable from the eye-movement frequency of a concentrated gaze of a vehicle driver,
determining a current eye-movement frequency of the user from the eye-movement frequency data,
comparing the current frequency with the first threshold, and
triggering a notification signal intended for the user when the current frequency is greater that the first threshold.
