Pinch strength demo with the leap motion skeletal model.
This example shows how “pinch strength” can be detected with decent accuracy by the new skeletal model. Note how the pinching fingers get colored blue as the pinch pose increases in strength.
Pinch strength is supposed to be a measure of “the holding strength of a pinch hand pose.” The strength is zero for an open hand, and blends to 1.0 when a pinching hand pose is recognized. Pinching can be done between the thumb and any other finger of the same hand.
Tracking can break down, however, when a user rotates their hand.
