The unit direction vector parallel to the swipe motion.
You can compare the components of the vector to classify the swipe as appropriate for your application. For example, if you are using swipes for two dimensional scrolling, you can compare the x and y values to determine if the swipe is primarily horizontal or vertical.

Number
duration
The elapsed duration of the recognized movement up to the frame containing this Gesture object, in microseconds.
The duration reported for the first Gesture in the sequence (with the start state) will typically be a small positive number since the movement must progress far enough for the Leap to recognize it as an intentional gesture.
