====== Default Gestures ======

GestureWorks by default creates a basic set of gestures to use. Below are the descriptions of gestures including gesture properties.

----

===== Drag =====

Type: **drag**
Id: **ndrag**
==== Properties ====

**drag_dx** - delta x
**drag_dy** - delta y

The 'ndrag' gesture can be activated by any number of touchpoints. When a touchdown is recognized on a touch object the position of the touch point is tracked. This change in the position of the touch point is mapped directly to the position of the touch object.

----

===== Rotate =====

Type: **rotate**
Id: **nrotate**
==== Properties ====

**rotate_dtheta** - rotate change

The 'nrotate' gesture is designed to provide object rotation functionality using any number of touch points.
----

===== Scale =====

Type: **scale**
Id: **nscale**
==== Properties ====

**scale_dsx** - factor of change of scale x
**scale_dsy** - factor of change of scale y

The 'nscale' gesture is designed to provide object scaling or zoom functionality using any number of touch points. 
This gesture can be activated by any number of touch points between 2 and 10.
----

===== Scroll =====

Type: **scroll**
Id: **nscroll**
==== Properties ====

**scroll_dx** - change of scroll x
**scroll_dy** - change of scroll y
The 'nscroll' gesture can be activated by any number of touchpoints. When a touchdown is recognized on a touch object, the average velocity of the touch points are tracked. If velocity of the cluster is above the translation threshold a scroll event is continuously dispatched with inertia.

----

===== Swipe =====

Type: **swipe**
Id: **nswipe**
==== Properties ====

**swipe_dx** - change of x
**swipe_dy** - change of y
The 'n-swipe' gesture can be activated by any number of touchpoints. When a touchdown is recognized on a touch object, the velocity and acceleration of the touch points are tracked. If acceleration of the cluster is below the acceleration threshold a swipe event is dispatched.

----

===== Flick =====

Type: **flick**
Id: **nflick**
==== Properties ====

**flick_dx** - change of x
**flick_dy** - change of y
The 'n-flick' gesture can be activated by any number of touchpoints. When a touchdown is recognized on a touch object, the velocity and acceleration of the touch points are tracked. If acceleration of the cluster is above the acceleration threshold a flick event is dispatched.

----

===== Tap =====

Type: **tap**
Id: **ntap**
==== Properties ====

**tap_x** - x of tap
**tap_y** - y of tap
**tap_n** - number of tap points

----

===== Double Tap =====

Type: **double_tap**
Id: **ndouble_tap**
==== Properties ====

**double_tap_x** - x of tap
**double_tap_y** - y of tap
**double_tap_n** - number of tap points

----

===== Hold =====

Type: **hold**
Id: **nhold**
==== Properties ====

**hold_x** - x of hold
**hold_y** - y of hold
**hold_n** - number of hold points
