Let’s have a look at how leapmotion looks like.
As we can see, leap motion contains one black screen as well as withe shell. However, the inner strcture is not as simple as it looks like, where there are two camera as well as one infrared sensor. Leap motion combined these sensors to rebuild the postion of all the joint’s postion.
And what we can tell from the pictrue above is that we do not need anything wearing on hands to make the performance happen. The detecton of leapmotion merely relies on the three sensors listed. Actually this is the merit of portabiliy.

Test detection of fingers open and close one by one. The detection works swiftly and accurately.

Test the condition of the changing pose of hands, and even the inverse of hands, the detection still works well. For the case of inverse detection of hands, the excellent tracking can ensure the consistancy of detection. In the gif, the curl of inversing hands can be cetected perfectly.
I guess you must feel like to have a try with leapmotion by yourself!
But where to find one?
Thus the last part of the passage is link of leapmotion, where you can find more about how to realize your control of abstrct world through your hands motion with the help of leapmotion!
