direction :Leap.Vector
-
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.
