- *
- * @class Gesture
- * @abstract
- * @memberof Leap
- * @classdesc
- * The Gesture class represents a recognized movement by the user.
- *
- * The Leap watches the activity within its field of view for certain movement
- * patterns typical of a user gesture or command. For example, a movement from side to
- * side with the hand can indicate a swipe gesture, while a finger poking forward
- * can indicate a screen tap gesture.
- *
- * When the Leap recognizes a gesture, it assigns an ID and adds a
- * Gesture object to the frame gesture list. For continuous gestures, which
- * occur over many frames, the Leap updates the gesture by adding
- * a Gesture object having the same ID and updated properties in each
- * subsequent frame.
- *
- * **Important:** Recognition for each type of gesture must be enabled;
- * otherwise **no gestures are recognized or reported**.
- *
- * Subclasses of Gesture define the properties for the specific movement patterns
- * recognized by the Leap.
- *
- * The Gesture subclasses for include:
- *
- * * CircleGesture -- A circular movement by a finger.
- * * SwipeGesture -- A straight line movement by the hand with fingers extended.
- * * ScreenTapGesture -- A forward tapping movement by a finger.
- * * KeyTapGesture -- A downward tapping movement by a finger.
- *
- * Circle and swipe gestures are continuous and these objects can have a
- * state of start, update, and stop.
- *
- * The screen tap gesture is a discrete gesture. The Leap only creates a single
- * ScreenTapGesture object appears for each tap and it always has a stop state.
- *
- * Get valid Gesture instances from a Frame object. You can get a list of gestures
- * from the Frame gestures array. You can also use the Frame gesture() method
- * to find a gesture in the current frame using an ID value obtained in a
- * previous frame.
- *
- * Gesture objects can be invalid. For example, when you get a gesture by ID
- * using Frame.gesture(), and there is no gesture with that ID in the current
- * frame, then gesture() returns an Invalid Gesture object (rather than a null
- * value). Always check object validity in situations where a gesture might be
- * invalid.

- *
- * @class Gesture
- * @abstract
- * @memberof Leap
- * @classdesc
- * The Gesture class represents a recognized movement by the user.
- *
- * The Leap watches the activity within its field of view for certain movement
- * patterns typical of a user gesture or command. For example, a movement from side to
- * side with the hand can indicate a swipe gesture, while a finger poking forward
- * can indicate a screen tap gesture.
- *
- * When the Leap recognizes a gesture, it assigns an ID and adds a
- * Gesture object to the frame gesture list. For continuous gestures, which
- * occur over many frames, the Leap updates the gesture by adding
- * a Gesture object having the same ID and updated properties in each
- * subsequent frame.
- *
- * **Important:** Recognition for each type of gesture must be enabled;
- * otherwise **no gestures are recognized or reported**.
- *
- * Subclasses of Gesture define the properties for the specific movement patterns
- * recognized by the Leap.
- *
- * The Gesture subclasses for include:
- *
- * * CircleGesture -- A circular movement by a finger.
- * * SwipeGesture -- A straight line movement by the hand with fingers extended.
- * * ScreenTapGesture -- A forward tapping movement by a finger.
- * * KeyTapGesture -- A downward tapping movement by a finger.
- *
- * Circle and swipe gestures are continuous and these objects can have a
- * state of start, update, and stop.
- *
- * The screen tap gesture is a discrete gesture. The Leap only creates a single
- * ScreenTapGesture object appears for each tap and it always has a stop state.
- *
- * Get valid Gesture instances from a Frame object. You can get a list of gestures
- * from the Frame gestures array. You can also use the Frame gesture() method
- * to find a gesture in the current frame using an ID value obtained in a
- * previous frame.
- *
- * Gesture objects can be invalid. For example, when you get a gesture by ID
- * using Frame.gesture(), and there is no gesture with that ID in the current
- * frame, then gesture() returns an Invalid Gesture object (rather than a null
- * value). Always check object validity in situations where a gesture might be
- * invalid.
