You can set those options corresponding to the following topics 
by using our touchscreen panel.

**************************************************************************
1.Calibration
    Touch the center of the cross, then you can test the results 
    of the calibration. Touch different areas on the screen, if 
    the cursor jumps to your fingertip every time you touch the 
    screen, click the "ok"  button to proceed, otherwise, click 
    "Adjust Again" to repeat the calibration.

    Why calibration is necessary?

    When you use mouse or keyboard, the cursor is part of the 
    image,but a touchscreen has an independent coordinate system.
    To convert touchscreen coordinates into image coordinates, 
    you must know the position of the image. Calibration gives 
    the information how to convert touchscreen coordinates into 
    image coordinates.
    
		For many reasons, perfect calibration cannot be achieved in 
		all circumstances. For example, the user can encounter 
		parallax problems with a change in position, or because the 
		present user is not the same stature as the person who 
		calibrated the screen. Even the most sophisticated calibration
		techniques can only partially overcome such variations. Most 
		touchscreen software uses only a four-point calibration
		sequence and instead relies on well-placed touch zones and 
		appropriate user feedback.

    Once calibrated, our touchscreen driver will be ready to run 
    automatically each time the system is restarted. Recalibration
    should only be necessary after moving or resizing the video 
    image, or after changing either the touchscreen, controller, or
    monitor.

2.Mouse button emulation mode
    There are four mouse button emulation modes: 
        Click on Touch; Click on Release; Drag; Drag, double-click.

    Click on Touch: 
        Left button clicking only. No dragging or right button is 
        supported. If you touch the screen in this mode, the mouse
        pointer will move to your fingertip and the left button
        "clicks". A click sound will confirm the click. The mouse 
        pointer will not move, nor will any other clicks be simulated
        until your finger is lifted and the screen retouched. This 
        mode works with large targets, recommended for public kiosk
        applications.

    Click on release: 
        Left button clicking only. No dragging or right button is 
        supported. In this mode, the mouse pointer follows your 
        sliding finger and the left button is clicked at the point 
        of release. You have the opportunity to adjust your touch 
        accurately and slowly. When the target is small, this mode 
        is suitable.

    Drag:
        Left button clicking and dragging. No right button is supported.
        In this mode, when you touch the screen, the left button is 
        held down and stays down until you release, dragging as you move.

    Drag, Double-click: 
        Same as drag mode, but supports double-clicking by tapping twice.
        Right button mode is supported also. In this mode, if the second
        touch occurs immediately after the first and is nearby, 
        a double-click will be simulated at the exact point of the first 
        touch. If you do not hear two click sounds, you have tapped too 
        fast. Recommended for windows operation and general use.

3.Hide arrow cursor
    Check this box will disable the arrow for all circumstances. Sometimes
    the arrow cursor is unuseful and can even be confusing to the user. 
    After you have turned off the arrow cursor, you have to use the 
    keyboard to turn it back on. Use the TAB key to select the hide arrow
    cursor check box and SPACE key to uncheck it.

**************************************************************************
4.Right button mode
    "Right Button", click it, then the "Right button" icon appears on the
    right-down corner of the screen, then touch the target, it means 
    clicking the Right Button on the target. Right button is unuseful 
    usually, but sometimes it can make things better.

************************************************************************** 
5.Handwriting demo
    The AccousticWave touchscreen can support z axis coordinate, this makes
    things more interesting. "Handwriting demo" program demonstrates the
    effects of z axis coordinate partially. The Readme.TXT file has the
    contents about how to use z axis coordinate in your program.

**************************************************************************
6.Remove Device
    "Remove Device", click it,then will delete your selected device item in
    "Device Interface" list tables.

**************************************************************************
7.Add Device
    "Add Device", click it, then will display the menu "Interface" and you
    may input the device name, will add the device name to "Device Interface"
    list tables.

**************************************************************************
8.Accept Device
    "Accept Device", click it, then the programe will scan all device in "
    Device Interface" list tables, application will know which device name
    interface normally.

**************************************************************************
Default "Deive Interface" list tables
    /dev/Serial_Port_0
    /dev/Serial_Port_1
    /dev/USB_Port_0
    /dev/USB_Port_1
