Abstract

A method and apparatus of detecting an input gesture command are disclosed. According to one example method of operation, a digital image may be obtained from a digital camera of a pre-defined controlled movement area. The method may also include comparing the digital image to a pre-stored background image previously obtained from the digital camera of the same pre-defined controlled movement area. The method may also include identifying one or more pixel differences between the digital image and the pre-stored background image and designating the digital image as having a detected input gesture command.

Claims

1. A method of detecting an input gesture command comprising:

obtaining at least one digital image from a digital camera of a pre-defined controlled movement area;

comparing, via a processor, the at least one digital image to at least one pre-stored background image previously obtained from the digital camera of the same pre-defined controlled movement area;

identifying, via the processor, at least one pixel difference between the at least one digital image and the at least one pre-stored background image; and

designating, via the processor, the at least one digital image as having a detected input gesture command.

2. The method of claim 1, further comprising:

triggering the digital camera to begin obtaining the at least one digital image based on a movement detected by an infrared (IR) sensor coupled to the processor associated with the digital camera.

3. The method of claim 1, further comprising:

converting content of the at least one digital image to a linear representation to identify a type of input gesture command.

4. The method of claim 3, wherein the linear representation comprises a plurality of gridpoints used to identify the user'"'"'s body part used for the input gesture command.

5. The method of claim 4, further comprising:

comparing the linear representation to a pre-stored linear representation to identify the type of input gesture command; and

identifying the type of input gesture command.

6. The method of claim 5, further comprising:

transmitting a command to a remote device based on the identified type of input gesture command.

7. The method of claim 1, wherein the digital camera is a complementary symmetry metal oxide semiconductor (CMOS) camera.

14. The apparatus of claim 1, wherein the digital camera is a complementary symmetry metal oxide semiconductor (CMOS) camera.

8. An apparatus configured to detect an input gesture command comprising:

a digital camera;

a receiver configured to receive at least one digital image from the digital camera of a pre-defined controlled movement area; and

a processor configured to

compare the at least one digital image to at least one pre-stored background image previously obtained from the digital camera of the same pre-defined controlled movement area,

identify at least one pixel difference between the at least one digital image and the at least one pre-stored background image, and

designate the at least one digital image as having a detected input gesture command.

9. The apparatus of claim 8 wherein the processor is further configured to trigger the digital camera to begin obtaining the at least one digital image based on a movement detected by an infrared (IR) sensor coupled to the processor associated with the digital camera.

10. The apparatus of claim 8, wherein the processor is further configured to convert content of the at least one digital image to a linear representation to identify a type of input gesture command.

11. The apparatus of claim 10, wherein the linear representation comprises a plurality of gridpoints used to identify the user'"'"'s body part used for the input gesture command.

12. The apparatus of claim 11, wherein the processor is further configured to compare the linear representation to a pre-stored linear representation to identify the type of input gesture command and identify the type of input gesture command.

13. The apparatus of claim 12, further comprising:

a transmitter configured to transmit a command to a remote device based on the identified type of input gesture command.

15. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to detect an input gesture command, the processor being further configured to perform:

obtaining at least one digital image from a digital camera of a pre-defined controlled movement area;

comparing, via a processor, the at least one digital image to at least one pre-stored background image previously obtained from the digital camera of the same pre-defined controlled movement area;

identifying, via the processor, at least one pixel difference between the at least one digital image and the at least one pre-stored background image; and

designating, via the processor, the at least one digital image as having a detected input gesture command.

16. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform:

triggering the digital camera to begin obtaining the at least one digital image based on a movement detected by an infrared (IR) sensor coupled to the processor associated with the digital camera.

17. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform:

converting content of the at least one digital image to a linear representation to identify a type of input gesture command.

18. The non-transitory computer readable storage medium of claim 17, wherein the linear representation comprises a plurality of gridpoints used to identify the user'"'"'s body part used for the input gesture command.

19. The non-transitory computer readable storage medium of claim 18, wherein the processor is further configured to perform:

comparing the linear representation to a pre-stored linear representation to identify the type of input gesture command; and

identifying the type of input gesture command.

20. The non-transitory computer readable storage medium of claim 15, wherein the processor is further configured to perform:

transmitting a command to a remote device based on the identified type of input gesture command.
