+##Product description
+This visualization example shows how to evaluate and handle touch events of MultiTouch displays in CODESYS. 
+If visualization is used on a MultiTouch display, then an additional control concept is available to the user. 
+Apart from the usual mouse and keyboard events, gestures and touch events are evaluated and processed.
+
+**Supported gestures**
+
+- Pan gesture: pressing, shifting and releasing with a finger moves the contents of a window or a tab 
+- Flick gesture: fast shifting of a finger in an area, i.e. "flicking", leads to switching between different visualization screens
+- Multi touch events: operating with several fingers at a time
+
+  Several elements in a visualization screen can be actuated at the same time with several fingers. Thus it is possible to develop a two-hand control or a virtual mixer in which several sliders can be actuated at the same time.
+
+The ``IGestureEventHandler`` interface of the ``VisuElems.VisuElemBase`` library enables IEC 61131-3 code to 
+be implemented in order to react to gestures. A gesture event can be intercepted and consequential actions can 
+be implemented.
+
+The following clients can execute visualization on a MultiTouch device
+
+- CODESYS TargetVisu on a device with Windows operating system 
+- CODESYS TargetVisu on a device with Linux operating system 
+
+
+##More information
+The project ``MultiTouchExample.project`` shows the usage of the interface ``IGestureEventHandler2``. 
+The function block ``GesturesHandler`` implements the interface ``IGestureEventHandler2``. At first the event 
+handler must be registered at the event manager. This is done in the method ``FB_Init`` of the function block 
+``GesturesHandler``. The methods ``HandleFlickGesture``, ``HandlePanGesture`` and ``HandleTouchEvent`` will be 
+called if a corresponding event occurs. 
+
+The example contains following functions:
+
+**Scrolling:**     Scrolling inside of frames and tab controls
+**Multiple inputs:**   Simultaneous control of input elements
+**Two-hand inputs:**   The example demonstrates the input handling with two hands
+**Handling in IEC:**   Event handling of touch events in IEC 61131-3; the example displays the current touch points at the screen
+**Flick detection:**   Counts the horizontal and vertical flick events
