A SEMINAR REPORT ON TOUCH SCREEN


[attachment=37080]

INTRODUCTION

A touch screen is computer display screen that is sensitive to
human touch, allowing a user to interact with the computer by
touching pictures or words on the screen. Touch screen are used
with information kiosks (an interactive computer terminal
available for public use, as one with internet access or site specific
information), computer based training devices, and system
designed to help individuals who have difficulty in manipulating a
mouse or keyboard. Touch screen technology can be used as an
alternative user interface with application that normally requires a
mouse, such as a web browser. Some applications are designed
specifically for touch screen technology, often having larger icon
and link than typical PC application. Monitors are available with
built in touch screen kit.
A touch screen kit includes a touch screen panel, a controller, and a
software driver. The touch screen panels are is a clear panel
attached externally to the monitors that plug in to a serial or a
universal serial Bus (USB) port a bus Card installed in side the
computer. The touch screen panel registers touch event and passes
these signal to controller. The controller then processes the signals
and sends the data to the processor. The software driver translates
the touch events into mouse events. Driver can be provided for
both Window and Macintosh operating systems. Internal touch
screen kits are available but require professional installation
because the must be installed inside the monitors.

HISTORY OF TOUCH SCREEM
TECHNOLOGY


Dr. Sam Hurst, founder of Elographics, developed the first “touch
screen”while he was an instructor at the university of Kentucky in 1971.
Ten stockholders founded Elographics, Inc. in March 1971, to produce
Graphical data Digitizers for use in research and industrial application, with
the, principal being Dr. Sam Hurst. He was on leave from the Oak Ridge
National Laboratory to tech at the University of Kentucky for two years,
where he was faced with a need to read a huge stack of strip chart data. It
would have taken two graduate student s approximately two month to do the
task. He started to thinking of a way to read the and during the process, the
“Elograph” (Electronic graphics) coordinate measuring system and
Elographics the company were born. The University Kentucky research
foundation applied for and was granted a patent on the Elograph. The
foundation granted an exclusive license to Elographics.

Why touch screen?

User interface PCs are quickly becoming the control device of choices for
the plant floor, machine control and any application where the user interface
is important. This change has not been without its difficulties. One challenge
industrial PC manufacturers have faced is simplifying the human machine
interface while maintaining accuracy of input. Industrial grade touches
Screen system have quickly become the input device of choice for several
reasons. Touch systems generally have no additional hardware to mount and
protect, such as a mouse or keyboard. A flat panel display can also be sealed
by the factory to prevent damage from dust and water. The ultra thin nature
of a touch screen on a LCD saves critical space, which is a vital for most
application.
Durability is tested to over 35 million finger touches with no over
performance degradation. 1 million-touch life max.
Design Flexibility: -
Advanced design allows flat and spherical design.
Touch screen are very intuitive; it is natural for people to respond to there
environment by touching. Touch screen are usually manipulated with ease
and require minimal instrumentation training for a user. Best of all, touch
screens draw an operator “into” the application, improving accuracy
attention span and speed of response. Although the touch screen system for
the riggers of everyday life, for rugged environments and the best solution.

The Benefits of Touch Screen

·Reduce training expenses

Touch screen system are far easier to learn then traditional keyboard based.
Everyday retail function like Selection tender, editing and voiding line items
and capturing customer demographic information are made intuitive by
virtue of the touch screen- and the right touch screen software. Many
retailers, especially those in the service sector, sell items that cannot be
easily bar coded. Touch system make it easy to ring up these items and of
course, still to allow the use of all standard bar coded technologies. Studies
show reduction in training time in excess of 50% can be expected.
Enhanced POS function can be added with the knowledge that employees
will be able to utilizes them quickly and easily.

·Improve customer Service

If your customer have to wait for your employees to figure out how to use
the store’s system , you are going lose costumer. Touch screen system
eliminate this embarrassing and all too common, problem. Today’s retailers
need to learn as much as possible about there customers needs and buying
habits. Capturing customers information is a snap with touch screen POS
systems.

·Reduce Transaction Times

Studies show touch screen systems process transactions up to 60% faster
than traditional keyboard POS systems. One info touch’ customer has
clocked in with a traction rate of over 60 per Hrs. per register, over
20,000per day-with volunteers.

·Decrease Cost

In a touch screen POS system, the lay out of the color coded “keys” is
stored in file on your hard drive. Change to the layout can be accomplished
during the nightly poll of store data the time and expense of changing
hardware key caps is eliminated.

Software Driver

The driver is a software update for the PC system that allows the
touchscreen and computer to work together. It tells the computer's operating
system how to interpret the touch event information that is sent from the
controller. Most touch screen drivers today are a mouse-emulation type
driver. This makes touching the screen the same as clicking your mouse at
the same location on the screen. This allows the touchscreen to work with
existing software and allows new applications to be developed without the
need for touchscreen specific programming. Some equipment such as thin
client terminals, DVD players, and specialized computer systems either do
not use software drivers or they have their own built-in touch screen driver.

Comparing Touch Technologies

We offer touchscreen products with several of the most widely
used touchscreen technologies. Each type of screen has unique
characteristics that can make it a better choice for certain
applications. Follow the links below for information on the
different touch technologies that we offer and recommend. Please
contact us if you have any questions or would like assistance
selecting a touch technology for your application.

4-Wire Resistive Touchscreens

4-Wire Resistive touchscreen technology is used in the touch addons
that we offer for PC monitors and notebooks. It is a reliable
and affordable technology that is widely used by individuals and in
less demanding workplace applications. It is pressure sensitive so it
responds to any input device, including finger, gloved hand, or pen
stylus. Follow this link for more information.

5-Wire Resistive Touchscreens

We offer 5-Wire Resistive touchscreen technology with the CRT
and LCD touch monitors that we offer. It is a durable and accurate
technology that is widely used in demanding workplace
applications such as point-of-sale systems, industrial controls, and
medical systems. It is pressure sensitive so it responds to any input
device, including finger, gloved hand, or pen stylus. Follow this
link for more information.
