Abstract

Claims (61)

1. A method for drawing and fine tuned motor controls comprising:

displaying, with at least one processor, data comprising an activation zone via a display of a user device, wherein the activation zone comprises an annulus between two concentric circles, wherein a first circle of the two concentric circles is an inner circle with a first perimeter, wherein a second circle of the two concentric circles is an outer circle with a second perimeter;

receiving, with at least one processor, gaze data from a user comprising a gaze point;

determining, with at least one processor, a location of the gaze point is within the activation zone, wherein any part of the display of the user device inside of the perimeter of the first circle is outside of the activation zone, and wherein any part of the display of the user device outside of the perimeter of the second circle is outside of the activation zone;

moving, with at least one processor, a cursor in a direction of the gaze point based on determining the location of the gaze point is within the activation zone;

in response to moving the cursor in a direction of the gaze point, causing, with at least one processor, an action to be performed; and

displaying, with at least one processor, data associated with the action via the display of the user device.

2. The method of claim 1 , wherein determining the location of the gaze point is within the activation zone comprises:

determining a time the location of the gaze point is within the activation zone satisfies a threshold value; and

determining the location of the gaze point is within the activation zone based on determining the time the location of the gaze point is within the activation zone satisfies the threshold value.

3. The method of claim 1 , wherein moving the cursor in the direction of the gaze point comprises:

determining a location of the cursor;

determining a distance between the location of the gaze point and the location of the cursor; and

moving the cursor in the direction of the gaze point at a speed, wherein the speed of a cursor movement is based on the distance between the location of the gaze point and the location of the cursor.

4. The method of claim 1 , further comprising:

stopping movement of the cursor when the location of the gaze point is not within the activation zone, wherein stopping movement of the cursor causes the action to end.

5. The method of claim 1 , wherein an outer edge of the activation zone comprises an icon, the method further comprising:

receiving a selection of the icon by the user; and

stopping movement of the cursor, wherein stopping movement of the cursor causes the action to end.

6. The method of claim 1 , wherein a size of the activation zone is based on a percentage of a width of a display of the user device.

7. A system for drawing and fine tuned motor controls comprising:

at least one processor, the at least one processor programmed or configured to:

display data comprising an activation zone via a display of a user device, wherein the activation zone comprises an annulus between two concentric circles, wherein a first circle of the two concentric circles is an inner circle with a first perimeter, wherein a second circle of the two concentric circles is an outer circle with a second perimeter;

receiving, with at least one processor, gaze data from a user comprising a gaze point;

determine a location of the gaze point is within the activation zone, wherein any part of the display of the user device inside of the perimeter of the first circle is outside of the activation zone, and wherein any part of the display of the user device outside of the perimeter of the second circle is outside of the activation zone;

move a cursor in a direction of the gaze point based on determining the location of the gaze point is within the activation zone;

in response to moving the cursor in a direction of the gaze point, cause an action to be performed; and

display data associated with the action via the display of the user device.

8. The system of claim 7 , wherein, when determining the location of the gaze point is within the activation zone, the at least one processor is programmed or configured to:

determine a time the location of the gaze point is within the activation zone satisfies a threshold value; and

determine the location of the gaze point is within the activation zone based on determining the time the location of the gaze point is within the activation zone satisfies the threshold value.

9. The system of claim 7 , wherein, when moving the cursor in the direction of the gaze point, the at least one processor is programmed or configured to:

determine a location of the cursor;

determine a distance between the location of the gaze point and the location of the cursor; and

move the cursor in the direction of the gaze point at a speed, wherein the speed of a cursor movement is based on the distance between the location of the gaze point and the location of the cursor.

10. The system of claim 7 , wherein the at least one processor is further programmed or configured to:

stop movement of the cursor when the location of the gaze point is not within the activation zone, wherein stopping movement of the cursor causes the action to end.

11. The system of claim 7 , wherein an outer edge of the activation zone comprises an icon, and wherein the at least one processor is further programmed or configured to:

receive a selection of the icon by the user; and

stop movement of the cursor, wherein stopping movement of the cursor causes the action to end.

12. The system of claim 7 , wherein a size of the activation zone is based on a percentage of a width of a display of the user device.

13. A computer program product comprising at least one non-transitory computer-readable medium including one or more instructions that, when executed by at least one processor, cause the at least one processor to:

display data comprising an activation zone via a display of a user device, wherein the activation zone comprises an annulus between two concentric circles, wherein a first circle of the two concentric circles is an inner circle with a first perimeter, wherein a second circle of the two concentric circles is an outer circle with a second perimeter;

receive gaze data from a user comprising a gaze point;

determine a location of the gaze point is within the activation zone, wherein any part of the display of the user device inside of the perimeter of the first circle is outside of the activation zone, and wherein any part of the display of the user device outside of the perimeter of the second circle is outside of the activation zone;

move a cursor in a direction of the gaze point based on determining the location of the gaze point is within the activation zone;

in response to moving the cursor in a direction of the gaze point, cause an action to be performed; and

display data associated with the action via the display of the user device.

14. The computer program product of claim 13 , wherein, when determining the location of the gaze point is within the activation zone, the instructions cause the at least one processor to:

determine a time the location of the gaze point is within the activation zone satisfies a threshold value; and

determine the location of the gaze point is within the activation zone based on determining the time the location of the gaze point is within the activation zone satisfies the threshold value.

15. The computer program product of claim 13 , wherein, when moving the cursor in the direction of the gaze point, the instructions cause the at least one processor to:

determine a location of the cursor;

determine a distance between the location of the gaze point and the location of the cursor; and

move the cursor in the direction of the gaze point at a speed, wherein the speed of a cursor movement is based on the distance between the location of the gaze point and the location of the cursor.

16. The computer program product of claim 13 , wherein the instructions further cause the at least one processor to:

stop movement of the cursor when the location of the gaze point is not within the activation zone, wherein stopping movement of the cursor causes the action to end.

17. The computer program product of claim 13 , wherein an outer edge of the activation zone comprises an icon, and wherein the instructions further cause the at least one processor to:

receive a selection of the icon by the user; and

stop movement of the cursor, wherein stopping movement of the cursor causes the action to end.

18. The computer program of claim 13 , wherein a size of the activation zone is based on a percentage of a width of a display of the user device.
