Section
Touch screens are a common means to interface operator inputs to a system. The universal
standard of Windows GUI (Graphical User Interface) has significantly increased the use of
touch screens.
There are four main touch technologies. The technologies are resistive, surface acoustic
wave (SAW), capacitive, and infrared (IR). Each touch technology has advantages and
disadvantages based on different user applications.
All Vartech Systems displays configured with a touch screen are supplied with a CDROM
which includes user manuals, application software, and drivers for various operating systems.
Insert the supplied CDROM into a CDROM drive and follow the installation instructions that
will appear on the screen.
Limited technical support is available by contacting Vartech Systems customer support at
800-223-8050.
