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 9036CH5/6300A5 control board and Windows XP/2003/Vista/7 driver. Our
advanced design supports from 2 to 6 monitors that can be split horizontally or
vertically.
