Gesture Recognition Architecture (Compact 7)
3/12/2014
The following diagram shows the gesture recognition architecture, including the touch driver, the Graphics, Windowing, and Events Subsystem (GWES) touch input, the user input queue, the gesture core, and the recognizers.

The diagram shows four code modules that are central to gesture recognition, and some of their source files. The topics in this section discuss the modules individually. A touch event (for example, a finger touches the screen) passes from the touch driver to touch input, then to the user input queue, then to the gesture core, and finally to the recognizers. The pink arrows show this flow. When a recognizer recognizes a gesture, it calls Gesture to report it, and the gesture core creates a gesture message. The blue arrows show this flow.
