1. A method, performed by a wearable eyeglass frame comprising at least one bio-signal measuring sensor and a display, the at least one bio-signal measuring sensor including at least one electrophysiological sensor, the at least one electrophysiological sensor including at least one EOG sensor and at least one EEG sensor, comprising:

  • displaying at least one item on the display;

    acquiring bio-signal data from a user using the at least one bio-signal measuring sensor, the bio-signal data comprising electrophysiological data from the at least one electrophysiological sensor;

    processing the bio-signal data, in accordance with a profile associated with the user to compute at least one brainwave state measurement and at least one eye activity measurement, the at least one eye activity measurement computed using the electrophysiological data from the at least one EOG sensor, the at least one eye activity measurement based on changes in an electrical potential of the bio-signal data from the at least one EOG sensor, wherein the processing comprises detecting, within the at least one brainwave state measurement, an event related potential associated with the display of the at least one item;

    determining, using the at least one eye activity measurement, positions and times of eye movements between points of focus on elements in a scene, the scene including the display, and positions and times of eye gaze fixations on points of focus on elements in the scene;

    identifying a pattern of saccadic eye movement based on the eye movements and the eye gaze fixations;

    upon identification of the pattern, associating the pattern with a condition of saliences of elements of the scene to the user;

    determining a correspondence between the at least one brainwave state measurement, the eye movements, the eye gaze fixations, the saliences of elements of the scene to the user, and at least one predefined device control action; and

    in accordance with the determined correspondence, controlling operation of at least one component of the eyeglass frame by modifying or initiating the modification of an image displayed on the display.
