### 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 two or three-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. Click sound on touches

Checking this box enables a "click" sound for each touch. Audible feedback makes you feel better when you touch the screen.

## 4. 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.

### 5. Beep sound

Using Beep settings in our touchscreen control panel, you can select when it beeps, its beep frequency(tone) and duration time. Touching the screen, you can test the beep effects. You can select again immediately if you are not satisfied with the effects.

### 6. Right button mode

Click the "start" button, point to "Program" -> "MAStouch USB Touchscreen" -> "Right Button", click it, then the "Right button" icon appears on the left-upper corner of the screen, you can drag the icon to everywhere on the screen. Touch the "Right Button" icon, 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.

### 7. Handwriting demo

The Surface Acoustic Wave 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.
