Gesture Recognition Architecture (Compact 2013)
3/26/2014
The gesture recognition architecture consists of four modules that are central to gesture recognition, including the touch driver, the Graphics, Windowing, and Events Subsystem (GWES) touch input, the user input queue, the gesture core, and the recognizers.
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. When a recognizer recognizes a gesture, it calls Gesture to report it, and the gesture core creates a gesture message.
