public class ProximityConcurrencyConstraint
extends ConcurrencyConstraint

This class represents a two-fold constraint. First the gestures have to be performed concurrently and secondly, they have to be performed in each others vicinity. The minimum and maximum distance has to be defined. This distance is the diagonal of the rectangular bounding box of the gestures for 2D gestures, for 3D gestures it is the diagonal of each facet of a cubic bounding space.
