Abstract: Methods, devices, and processor-readable media for adjusting the control-display gain of a gesture-controlled device are described. Adjusting the control-display gain may facilitate user interaction with content or UI elements rendered on a display screen of the gesture-controlled device. The control-display gain may be adjusted based on a property of how a mid-air dragging gesture is being performed by a user's hand. The property may be the location of the gesture, the orientation of the hand performing the gesture, or the velocity of the gesture. A hand that becomes stationary for a threshold time period while performing the dragging gesture may adjust the control-display gain to a different level. Control-display gain may be set to a different value based on the current velocity of the hand performing the gesture. The control-display gain levels may be selected from a continuous range of values or a set of discrete values. Devices for performing the methods are described.

Abstract: Method of analyzing eye tracking data for estimating user's cognitive and emotional level of consumption of visual information. A training machine learning model is trained using a data set containing gaze information of known training users, their known cognitive levels and their EEG signal measurements. A calibrating machine learning model is trained using a data set of calibrating visual information displayed to a user, calibrating gaze tracks of that user, calibrating actions data of that user, and calibrating session data related to the session environment. The device displays to that user a target visual information and records target eye tracking data of that user in response to consuming the target information. The recorded target eye tracking data is calibrated via the calibrating machine learning model. The calibrated target eye tracking data is fed into the training machine learning model, which estimates the cognitive levels of consumption of the target visual information of that user.
