TS9000/TS9050 TouchStar Systems User Manual
• Logging On to the Network
The TouchStar is shipped with network drivers that will
allow a specific network connection whenever the system is
booted.
Terminal Emulation Mode
The TouchStar system can be configured to operate in terminal
emulation mode by running a terminal emulation application
loaded on a PCMCIA card or Flash Disk. Terminal emulation
programs are available from a number of sources to operate
with a variety of hosts.
THE TOUCHSCREEN SUBSYSTEM AND
TOUCH-BASED OPERATION
The touchscreen subsystem is a collection of components that
provides the touch-based control of the TouchStar computer.
These components – the touch frame, and touch controller
firmware – combined with specific touch-based programming
techniques, allow touch-based applications to be implemented
on the TouchStar system.
Touchscreen Components
• Touch Frame and Protective Bezel
The touch frame is a screen overlay mounted on top of the
TouchStar’s video display. Around the periphery of the
overlay, behind a protective bezel, are 34 horizontal and 26
vertical infrared emitter/detector pairs mounted on oppo-
site sides. These emitter/detector pairs form a grid of
scanning beams which detect where the video display is
touched. The location information is passed to the
TouchStar’s CPU by the touch system controller firmware.
• Touch Controller Firmware and Driver Software
The touch controller firmware accepts and interprets
incoming coordinate data from the touch frame. The firm-
ware outputs specific coded data based upon the physical
location on the screen that was touched. The touch driver
software provides additional smoothing and anti-aliasing to
support cursor tracking for mouse-based touch applications.
The TouchStar system currently supports DOS, Windows,
Windows 95, Windows NT, and Windows for Workgroups
driver software.
