Eye tracking laser pointer

1. A method, comprising:

detecting, using a gaze tracking system of a device, a position of user gaze with respect to a display;

sending, through a display interface, display information including an added visual element associated with the position of user gaze, wherein the added visual element comprises an indicator associated with the position of user gaze;

tracking, using the gaze tracking system, change in the position of user gaze with respect to the display;

moving, using a processor, the added visual element responsive to change in the position of user gaze with respect to the display, wherein the moving comprises a discontinuous animated tracking movement of the added visual element on the display according to data provided by the gaze tracking system;

detecting a predetermined hand gesture that does not comprise touch contact with the device; and

decoupling, in response to the predetermined hand gesture, movement of the added visual element from the user gaze for a duration until the user ceases the predetermined hand gesture, wherein the decoupling maintains the added visual element in a last known position associated with the position of user gaze based upon detecting the predetermined hand gesture.

2. The method of claim 1 , wherein the sending of the added visual element is controlled according to the predetermined hand gesture.

3. The method of claim 1 , wherein said sending and said moving occur in a presentation mode.

4. The method of claim 1 , wherein the gaze tracking system of is co-located with the display.

5. The method of claim 1 , wherein the added visual element is a laser pointer indication.

6. The method of claim 1 , wherein the moving comprises a smoothed animated tracking movement of the added visual element on the display according to data provided by the gaze tracking system.

7. The method of claim 1 , wherein the animated tracking movement is controlled according to one or more underlying applications being utilized.

8. An apparatus, comprising:

a display;

a display interface;

a gaze tracking system that captures image data of a user of the apparatus;

a processor operatively coupled to the gaze tracking system; and

a memory storing instructions executable by the processor to:

detect, using the gaze tracking system, a position of user gaze with respect to the display;

send, through the display interface, display information including an added visual element associated with the position of user gaze, wherein the added visual element comprises an indicator associated with the position of user gaze;

track, using the gaze tracking system, change in the position of user gaze with respect to the display;

move the added visual element responsive to change in the position of user gaze with respect to the display, wherein the moving comprises a discontinuous animated tracking movement of the added visual element on the display according to data provided by the gaze tracking system;

detect a predetermined hand gesture that does not comprise touch contact with the device; and

decouple, in response to the predetermined hand gesture, movement of the added visual element from the user gaze for a duration until the user ceases the predetermined hand gesture, wherein the instructions to decouple comprises instructions to maintain the added visual element in a last known position associated with the position of user gaze based upon detecting the predetermined hand gesture.

9. The apparatus of claim 8 , wherein the added visual element is controlled according to the predetermined hand gesture.

10. The apparatus of claim 8 , wherein sending and moving of the added visual element occur in a presentation mode.

11. The apparatus of claim 8 , wherein the gaze tracking system of is co-located with the display.

12. The apparatus of claim 8 , wherein the added visual element is a laser pointer indication.

13. The apparatus of claim 8 , wherein moving of the added visual element comprises a smoothed animated tracking movement of the added visual element on the display according to data provided by the gaze tracking system.

14. A computer program product, comprising:

a storage device having code stored therewith and executable by a processor, the code comprising:

code that detects, using a gaze tracking system of a device, a position of user gaze with respect to a display;

code that sends, through a display interface, display information including an added visual element associated with the position of user gaze, wherein the added visual element comprises an indicator associated with the position of user gaze;

code that tracks, using the gaze tracking system, change in the position of user gaze with respect to the display;

code that moves, using a processor, the added visual element responsive to change in the position of user gaze with respect to the display, wherein the moving comprises a discontinuous animated tracking movement of the added visual element on the display according to data provided by the gaze tracking system;

code that detects a predetermined hand gesture that does not comprise touch contact with the device; and

code that decouples, in response to the predetermined hand gesture, movement of the added visual element from the of user gaze for a duration until the user ceases the predetermined hand gesture, wherein the code that decouples comprises code that maintains the added visual element in a last known position associated with the position of user gaze based upon detecting the predetermined hand gesture.
