Abstract

A display system including a panel 110 with a surface 116 to display images. The system includes a three dimensional optical sensor 115. The three dimensional optical sensor can include a field of view 135 that includes a front surface of the display system 100 and a volume in front of the front surface of the display system. A controller 190 can receive information from the three dimensional optical sensor and can interpret the information from the three dimensional optical sensor as a gesture of an object 120 in the volume.

Claims

1. A display system comprising:

a panel 110 with a surface 116 to display images;

a three dimensional optical sensor 115 including a field of view 135 that includes a front surface of the display system 100 and a volume in front of the front surface of the display system; and

a controller 190 to receive information from the three dimensional optical sensor and to determine if the information from the three dimensional optical sensor is a gesture of an object 120 in the volume.

2. The display system of claim 1, wherein a gesture is contacting the front surface 106 of the display system 100.

3. The display system of claim 2, wherein the information includes a first object in the volume and a second object contacting the front surface.

4. The display system of claim 1, further comprising a computer readable medium 685 to store gestures and associate the gestures with a computer function.

5. The display system of claim 2, wherein the controller accesses the computer readable medium 685 to determine the function.

6. The display system of claim 1, wherein the volume is between the front surface 106 and a volume distance.

7. The display system of claim 1, wherein the information from the three dimensional optical sensor 115 causes the controller 190 to zoom in on an image 518b on the display if the object moves toward the display system, then closes and moves away from the display system.

8. A method, comprising:

receiving at a controller 190 information from a three dimensional optical sensor 115;

determining with the controller 190 if the information received corresponds to a first gesture greater than the contact distance from a display system 100; and

determining with the controller if the information received corresponds to a second gesture less than a contact distance from the display system 100.

9. The method of claim 8, further comprising activating a first function of a computing system if it is determined that the first gesture corresponds to the first function.

10. The method of claim 8, further comprising activating a second function of a computing system if it is determined that the second gesture corresponds to the second function.

11. The method of claim 8, further comprising storing second information of different gestures in a computer readable medium 685.

12. The method of claim 11, further comprising comparing the information received from the three dimensional optical sensor and the second information in the computer readable medium.

13. The method of claim 12, further comprising zooming in on an image on the display if the information.

14. A computer readable medium comprising instructions that if executed cause a processor to:

receive information from a three dimensional optical sensor 115;

determine if the information received corresponds to a first gesture outside of the contact distance from a display system 100; and

determine if the information received corresponds to a second gesture less than a contact distance from the surface of the display system.

15. The computer readable medium of claim 14 further comprising instructions that if executed cause a processor to activate a first function of a computing system if it is determined that the first gesture corresponds to the first function.
