Anyone ever think about that with using gesturing, we can make some action in your desktop or laptop without using your mouse. For example, moving your head to the left, your mouse pointer will be go to the left, or even move your finger or hand in your webcam to control the mouse. Anyway, this type of scene have seen in a movie before, the Minority Report. Some how, this can be really happen in real life, just try to see this movie:

And for those feel interesting, you can go to MIT's project site for have an review on the report. I am planning to use my webcam to explore on the gesturing action too.
