I am using two leap sensors near each other to track each hand individually, however I sometimes lose tracking and when I look at the raw images I can see that the hand is not illuminated very well when the tracking is lost. Therefore, I was wondering if it is possible to use external infrared sources to improve the lighting and if this is going to help. Or if there are any other ways to improve illumination, I can reduce the background lighting slightly or perhaps distance the leap sensors but this is not prefered for what I want to do.
