Grab strength demo with the leap motion skeletal model.
This example shows how “grab strength” can be detected with decent accuracy by the new skeletal model. Note how the fingers redden as the hand becomes a fist.
Grab strength is supposed to be a measure of “the strength of a grab hand pose.” The strength is zero for an open hand, and blends to 1.0 when a grabbing hand pose is recognized.
Tracking can break down, however, when a user rotates their hand.
