5 .2 Software Function Description
Description for each of the software functions shown in the table above follows:
Standard Calibration
The Standard Calibration function lets you match the touch screen to your display so that
the point you touch is accurately tracked on screen. Standard calibration only requires
four points for calibration and one point for confirmation. Under normal circumstances,
Standard Calibration is all you need to perform an accurate calibration.
Advanced Calibration
The Advanced Calibration function improves the accuracy of calibration by using more
involved engineering calculations. Use this function only if you have tried the Standard
Calibration and there is still a discrepancy in the way the touch screen maps to the
display. You can choose 4, 9, 16 or 25 points to calibrate, though we suggest that you
first try 9 points, if it is still not tracking well then try 16 or 25 points. The more points you
use for calibration, the greater the accuracy. Errors in calibration may occur due to
viewing angle, or individual skill, and there may be little difference in using 16 or 25
points. Note that a stylus is recommended for the most accurate results.
Multiple Monitors
Until now most touch screen systems only support one monitor, and users of multiple
monitors have not been able to use touch screen systems. This situation has inspired
PenMount to design and develop Multiple Monitors support using the PenMount 9036
control board and Windows 2000/XP/Vista/7 driver. Our advanced design supports from
2 to 6 monitors that can be split horizontally or vertically.
Requirements
Before using the Multiple Monitor function, you need the following:
1. A display card that supports multiple monitors such as the Matrox, nVidia, ATI, etc.
(Two or more display cards supported by Windows are also OK.)
2. Two or more touch screens
3. Two or more serial ports
Before using Multiple Monitors you must have two or more monitors that are in extension
mode. For display cards that support multiple monitors, we suggest you consider Matrox,
nVidia, or ATI cards and inquire about operation and usability issues.
Note:
Before you can use multiple monitors, you need to map each monitor.
