Abstract: A device for determining a behavior of a target user, the device including a sensing unit configured to face at least one eye area of a target user, the sensing unit being configured to acquire a plurality of target signals representative of a variation of at least one characteristic of the at least one eye area of the target user, the sensing unit including at least one sensor, and the at least one sensor being oriented towards the eye area. The device also includes a controller configured to provide a machine learning algorithm, provide a plurality of objective target data related to the acquired target signals as an input to the machine learning algorithm, and determine a behavior of the target user as an output of the machine learning algorithm.
