A processing module in the computer causes the display to present graphical feedback information in the form of a data-manipulating window, which visually confirms any entered control commands. The data-manipulating window is presented at a position relative to an active control object on the display, such that a center point of the window is located within a relatively small offset distance from a center point of the active control object. The window includes graphical information, which symbolizes and activity portion of the display presently being the object of an eye-tracker-controlled entry of control commands. Moreover the information in the window is repeatedly updated in response to the eye-tracker-controlled entry of control commands. |
