An input device for interfacing with a computing device is provided. The input device includes a body configured to be held within a human hand. The input device includes a light emitting diode (LED) affixed to the body and a power supply for the LED. A mode change activator is integrated into the body, where the mode change activator is configured to cause a change of a color of a light originating from the LED. The color change is capable of being detected to cause a mode change at the computing device. Methods for detecting input commands from an input source within a field of sight of an image capture device, and a computing system which includes the input device are provided.

1. A method for triggering input commands of a program run on a computing system, comprising: identifying a light source within a field of view in front of an image capture device that is located near a display screen, the light source being set to always on during the identifying and pointed toward the image capture device;viewing the light source as it is pointed toward the image capture device, the display screen illustrating objects that can be interacted with;masking pixels not associated with the light source, the masking acting to ignore pixels not associated with the light source, the masking further includes adjusting an amount of light entering the image capture device by adjusting an aperture of the image capture device;detecting a change in light color emitted from the light source, the detecting occurring while the light source is moved in space and tracked; andtriggering an input command at the program run on the computing system to initiate an action that can be shown on the display screen, the triggering of the input command occurring in response to the detected change in light color. 2. The method of claim 1, wherein the light source is a light emitting diode (LED) capable of emitting multiple colors of light. 3. The method of claim 1, wherein the method operation of masking pixels includes; reducing the aperture of the image capture device. 4. The method of claim 1, wherein the input command causes a mode change linked to a cursor displayed on the display screen associated with the computing system. 5. The method of claim 1, further including: calculating a centroid of pixels associated with the light source in an image taken by the image capture device, wherein triggering the action shown on the display screen is based on the centroid. 6. The method of claim 5, wherein calculating the centroid further includes: determining pixels associated with the light source in the image;assigning a value to each of the determined pixels based on the association with the light source; andcalculating the centroid by performing a weighted average of coordinates of the pixels, the weighted average being based on the value assigned to each pixel. 7. The method of claim 5, further comprising: translating coordinates of the centroid to a location on the display screen associated with the computing system;detecting movement of the light source within the field of view; andcorrelating the movement of the light source to movement of a cursor on the display screen. 8. The method of claim 1, further including: adjusting an exposure time of the image capture device to track a pre-determined pixel value associated with the light source. 9. A method for triggering input commands of a program run on a computing system, comprising: identifying a light source within a field of view in front of an image capture device that is located near a display screen, the light source being set to always on during the identifying and pointed toward the image capture device, the identifying includes defining an area representing the light source within a grid identifiable in image data produced by the image capture device and expanding the area representing the light source within the grid, the expanding occurring by producing diffusion of light at the light source;masking pixels not associated with the light source, the masking acting to ignore pixels not associated with the light source, the masking further includes adjusting an amount of light entering the image capture device by adjusting an aperture of the image capture device;detecting a change in light color emitted from the light source in the area that is expanded that represents the light source, having the produced diffusion of light; andtriggering an input command, based on the detected change in light color, at the program run on the computing system to initiate an action that can be shown on the display screen. 10. The method of claim 9, wherein the method operation of identifying a light source within the field of view includes, detecting a position in the image data of an image representing the light source based on a light color of pixels in the image; andcalculating a centroid of the image representing the light source through a grid associated with the image capture device. 11. The method of claim 10, further comprising: translating coordinates of the centroid to a location on a display screen associated with the computing system;detecting movement of the light source within the field of view; andcorrelating the movement of the light source to movement of a cursor on the display screen. 12. A method for detecting input commands from an input source within a field of sight of an image capture device positioned near a display screen, comprising: identifying pixels in image data captured by the image capture device as associated with the input source, wherein the input source is defined to be always on during the identifying;masking pixels not associated with the input source, the masking acting to convert pixels not associated with the input source as black, the masking further includes minimizing an amount of light entering the image capture device by reducing an aperture of the image capture device;detecting a first color light from the input source through the image capture device, the first color light being directed in a direction of the display screen and the image capture device, such that directing the first color enables interactive movement of a cursor on the display screen;while tracking movement in space of the input source, detecting a change from the first color light to a second color light; andpresenting a mode change in response to changing to the second color light, the mode change operating to initiate an action that can be shown on the display screen, the operations processed by a processor. 13. The method of claim 12 wherein the method operation of detecting a first color light signal from the input source through the image capture device includes, determining a location of a center of the first color light signal on a coordinate system associated with the image capture device; andmapping the location to a corresponding location on a display screen. 14. The method of claim 12 wherein the method operation of detecting a change from the first color light to a second color light includes, detecting the second color light from the input source; andcomparing pixel values associated with the first color light to pixel values associated with the second color light. 15. The method of claim 12 further comprising: reverting to the first color light from the second color light; andin response to reverting to the first color light, terminating the mode change. 16. The method of claim 12 wherein the mode change is associated with one of a click and drag operation or a highlighting operation. 17. The method of claim 12 wherein the first color light and the second color light originate from one of a single light emitting diode or multiple light emitting diodes.
