Abstract

A system and method for controlling a vehicle system is presented. An icon is displayed on a display. The icon is associated with a function of the vehicle system and has an entrance zone about a center of the icon and an exit zone about the center of the icon. The exit zone is larger than the entrance zone. A location of a gaze of a user upon the display is detected using an eye gaze detection system. When the location of the gaze of the user is within the entrance zone, an indication that the icon is selected is presented. When the location of the gaze of the user is outside the exit zone, an indication that the icon is deselected is presented.

Claims

1. A method for controlling a vehicle system, comprising:

displaying an icon on a display, the icon being associated with a function of the vehicle system and having an entrance zone about a center of the icon and an exit zone about the center of the icon, the exit zone being larger than the entrance zone;

detecting a location of a gaze of a user upon the display using an eye gaze detection system;

when the location of the gaze of the user is within the entrance zone, indicating that the icon is selected; and

when the location of the gaze of the user is outside the exit zone, indicating that the icon is deselected.

2. The method of claim 1, wherein the display includes a virtual display.

3. The method of claim 1, wherein indicating that the icon is selected includes modifying a central region of the icon while leaving a perimeter of the icon substantially unchanged.

4. The method of claim 3, wherein modifying a central region of the icon includes displaying a dot over a center of the icon.

5. The method of claim 1, wherein a dimension of the entrance zone is at least partially determined by an accuracy of the eye gaze detection system.

6. The method of claim 5, wherein a dimension of the exit zone is at least partially determined by the dimension of the entrance zone.

7. The method of claim 1, wherein the icon includes an image or text.

8. A method for controlling an electronic system, comprising:

displaying an icon on a display, the icon having an entrance zone and an exit zone;

detecting a location of a gaze of a user upon the display;

when the location of the gaze of the user is within the entrance zone, selecting the icon; and

when the location of the gaze of the user is outside the exit zone, deselecting the icon.

9. The method of claim 8, wherein the display includes a virtual display.

10. The method of claim 8, wherein selecting the icon includes modifying a central region of the icon while leaving a perimeter of the icon substantially unchanged.

11. The method of claim 8, wherein a dimension of the entrance zone is at least partially determined by an accuracy of the location of the gaze of the user upon the display.

12. The method of claim 11, wherein a dimension of the exit zone is at least partially determined by the dimension of the entrance zone.

13. The method of claim 8, wherein the electronic system is in communication with a vehicle computer system.

14. A system for controlling a vehicle system, comprising:

a display configured to display an icon, the icon having an entrance zone about the icon and an exit zone about the icon, the exit zone being larger than the entrance zone;

an eye gaze detector configured to detect a location of a gaze of a user upon the display; and

a processor connected to the display and the eye gaze detector, the processor being configured to;

when the location of the gaze of the user is within the entrance zone, indicate that the icon is selected, and

when the location of the gaze of the user is outside the exit zone, indicate that the icon is deselected.

15. The system of claim 14, wherein the display includes a virtual display.

16. The system of claim 14, wherein, when the icon is selected, the processor is configured to modify a central region of the icon while leaving a perimeter of the icon substantially unchanged.

17. The system of claim 16, wherein modifying a central region of the icon includes displaying a dot over a center of the icon.

18. The system of claim 14, wherein a dimension of the entrance zone is at least partially determined by an accuracy of the eye gaze detector.

19. The system of claim 18, wherein a dimension of the exit zone is at least partially determined by the dimension of the entrance zone.

20. The system of claim 14, wherein the icon is associated with a function of the vehicle system, and further comprising a user interface configured to activate a selected icon and to control the function of the vehicle system.
