TOUCHSCREEN
SECTION 4
4.1 Introduction
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 five main touch technologies. The technologies are resistive, surface acoustic wave (SAW), capacitive,
infrared (IR), and projective capacitive. Each touch technology has advantages and disadvantages based on
different user applications.
4.2 Installation
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.
Technical support is available by contacting Vartech Systems customer support at 800-223-8050.
