EYE TRACKER WITH VISUAL FEEDBACK

摘要

The present invention relates to entry of control commands into a computer in response to eye-tracker detected movement sequences of a point of regard (130) over a graphical display, which is associated with the computer. A processing module in the computer causes the display to present graphical feedback information in the form of a data-manipulating window (220a), which visually conf irms any entered control commands. The data-manipulating window (220a) is presented at a position relative to an active control object (220A) 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 (220a) includes graphical information, which symbolizes an activity portion (210) of the display presently being the object of an eye-tracker-controlled entry of control commands. Moreover, the information in the window (220a) is repeatedly updated in response to the eye-tracker-controlled entry of control commands.
