Method (100) for calibrating a hearing aid (400) worn by a user, the method (100) being implemented by a processing and control unit (330) of a system (300) for calibrating the hearing aid (400), the method (100) comprising the steps: a) receiving (110) at least one acoustic stimulus; and for each one of the detected acoustic stimulus: b) determining (120) a first set of parameters of such a detected acoustic stimulus, c) receiving (130) at least one EEG response, d) determining (140) a second set of parameters of a respective EEG response, e) performing a first verifying step (150) wherein it is verified whether the first set of parameters and the second set of parameters satisfy or not at least one of predetermined first conditions, f) if the detected at least one EEG response is detected within a certain timeframe from a sound onset time and if the outcome of the first verifying step (150) is positive, storing (151) the detected acoustic stimulus in association with the detected at least one EEG response.

The present invention relates to a head mountable device (100) comprising an eye-tracking system (200), comprising a first detecting subsystem (210) configured to detect at least one first gaze parameter of a respective eye to be tracked when a user wears the head mountable device (100) so as to generate a first signal, wherein the first detecting subsystem (210) is of a low power monitoring type, and a second detecting subsystem (220) configured to detect at least one second gaze parameter of the respective eye so as to generate a second signal, the second detecting subsystem (220) comprises a plurality of detecting elements (221, 222), a processing and control unit (230) associated to the first detecting subsystem (210) and to the second detecting subsystem (220) configured to estimate a region of interest (400) among a predetermined plurality of regions of interest on the basis of said first signal, wherein the estimated region of interest (400) comprises the direction of the gaze of a respective eye to be tracked, the processing and control unit (230) is configured to selectively activate one or more of the detecting elements (221, 222) on the basis of the estimated region of interest (400) for subsequently estimating the direction of the gaze of the respective eye to be tracked inside the estimated region of interest (400) on the basis of said second signal with optimized hardware and computing energy consumption.

Systems and methods detect scan avoidance behaviors at a self-service point-of-sale (POS) terminal. The system includes a camera positioned to capture video images of an operational area of the POS terminal and a computer that determines when movement of an item by a customer operating the POS terminal indicates scan avoidance. The computer receives video images from the camera, preprocesses frames of the video images to suppress background and to track the movement of the item from a pickup area of the POS terminal, through a scan area of a scanner of the POS terminal, and to a bagging area of the POS terminal. The system may also include a 3D sensor for detecting depth data that is used to improve hand-item contact.
