Eye Tracker with Visual Feedback
First Claim
1. A system for controlling a computer apparatus associated with a graphical display, the computer apparatus being adapted to present a respective on-screen representation of at least one GUI-component on the display, the system comprising:
- an eye-tracker system adapted to determine a user'"'"'s point of regard on the display and in response to movement sequences of the point of regard over the display enter control commands into the computer apparatus, the eye-tracker system comprising a processing module adapted to produce graphical feedback information for presentation on the display to visually confirm any entered control commands, wherein the processing module is adapted to;
investigate whether the movement sequence of the point of regard fulfills an activation criterion with respect to an activation zone for any of the at least one control command, and if such a criterion is found to be fulfilled; and
present a data-manipulating window 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 comprising graphical information which symbolizes an activity portion of the display presently being the object of an eye-tracker-controlled entry of control commands, the window being presented such that the activity portion and the window are simultaneously visible on the display, andwherein the information in the data-manipulating window repeatedly updates in response to the eye-tracker-controlled entry of control commands.

Abstract
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 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, 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.

13. A method of controlling a computer apparatus being associated with a graphical display, the computer apparatus being adapted to present a, respective on-screen representation of at least one GUI-component on the display, the method comprising:
-
determining a user'"'"'s point of regard on the display and-in response to movement sequences of the point of regard over the display; receiving control commands entered into the computer apparatus; producing graphical feedback information for presentation on the display to visually confirm any entered control commands; investigating whether the movement sequence of the point of regard fulfills an activation criterion with respect to an activation zone for any of the at least one control command, and if such a criterion is found to be fulfilled; presenting a data-manipulating window 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 comprising graphical information which symbolizes an activity portion of the display presently being the object of an eye-tracker-controlled entry of control commands, the window being presented such that the activity portion and the window are simultaneously visible on the display; and updating repeatedly the information in the data-manipulating window in response to the eye-tracker-controlled entry of control commands. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
