A method for controlling an electronic system comprising a microprocessor, an eye tracker component, a display, and a memory, the memory comprising an executable code being executable by the microprocessor, the executable code when executed by the microprocessor causing the electronic system to perform the following steps of the method: • displaying a menu (20A; 20B; 20C) on a portion of a screen of the display, wherein at least one symbol being representation of information of the menu is displayed in the menu on the portion of the screen, the symbol being a single word, a combination of words, or an icon, each of the at least one symbol having its respective ranking, wherein when the ranking of the symbol is higher than an icon display threshold value it is displayed as its respective icon; • registering using the eye tracker component saccades of user eyes of a user, wherein each of the registered saccades has its starting and/or end gaze fixation point within the portion of the screen; • decreasing the icon display threshold value such that a number of the icons used for the displaying of the menu on the portion of the screen is increased when a number of the registered saccades exceeds a saccade number threshold value; and • iteratively repeating execution of the steps of: ∘ the displaying the menu on a portion of the screen of the display; ∘ the registering using the eye tracker component of saccades of the user eyes of the user, wherein each of the registered saccades has its starting and/or end gaze fixation point within the portion of the screen; and ∘ the decreasing of the icon display threshold value such that a number of the icons used for displaying of the menu on the portion of the screen is increased when a number of the registered saccades in the current iteration exceeds a saccade number threshold value; wherein the menu is displayed on the respective portion of the screen in each of the iterations, wherein the iterative repeating of execution of said steps is executed until the menu is fully displayed on the portion of the screen using the icons, wherein a screen area used for displaying on the screen of at least one of the icons is less than a screen area used for displaying on the screen of its respective word or word combination, wherein a screen area used for the displaying of the menu on the portion of the screen in one of the iterations is bigger than a screen area used for the displaying of the menu on the portion of the screen in another one of the iterations executed after the one of the iterations. • displaying a menu (20A; 20B; 20C) on a portion of a screen of the display, wherein at least one symbol being representation of information of the menu is displayed in the menu on the portion of the screen, the symbol being a single word, a combination of words, or an icon, each of the at least one symbol having its respective ranking, wherein when the ranking of the symbol is higher than an icon display threshold value it is displayed as its respective icon; • registering using the eye tracker component saccades of user eyes of a user, wherein each of the registered saccades has its starting and/or end gaze fixation point within the portion of the screen; • decreasing the icon display threshold value such that a number of the icons used for the displaying of the menu on the portion of the screen is increased when a number of the registered saccades exceeds a saccade number threshold value;

wherein the menu is displayed on the respective portion of the screen in each of the iterations, wherein the iterative repeating of execution of said steps is executed until the menu is fully displayed on the portion of the screen using the icons, wherein a screen area used for displaying on the screen of at least one of the icons is less than a screen area used for displaying on the screen of its respective word or word combination, wherein a screen area used for the displaying of the menu on the portion of the screen in one of the iterations is bigger than a screen area used for the displaying of the menu on the portion of the screen in another one of the iterations executed after the one of the iterations. ∘ the displaying the menu on a portion of the screen of the display; ∘ the registering using the eye tracker component of saccades of the user eyes of the user, wherein each of the registered saccades has its starting and/or end gaze fixation point within the portion of the screen; and ∘ the decreasing of the icon display threshold value such that a number of the icons used for displaying of the menu on the portion of the screen is increased when a number of the registered saccades in the current iteration exceeds a saccade number threshold value;
