ABSTRACT
A touch screen is a display that can detect the presence and location of a touch within the display area, generally refers to touch or contact to the display of the device by a finger or hand. Touch screen is also an input device. The screens are sensitive to pressure; a user interacts with the computer by touching pictures or words on the screen, Touch screens can also sense other passive objects, such as a stylus, the touch screen has two main attributes. First, it enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly with a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand. Such displays can be attached to computers or, as terminals, to networks. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.
INTRODUCTION
A touch screen is a 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 screens are used with information kiosks, computer-based training devices, and systems designed to help individuals who have difficulty manipulating a mouse or keyboard. Touch screen technology can be used as an alternative user interface with applications that normally require a mouse, such as a Web browser. Some applications are designed specifically for touch screen technology, often having larger icons and links than the typical PC application. Monitors are available with built-in touch screen technology or individuals can purchase a touch screen kit.
A touch screen kit includes a touch screen panel, a controller, and a software driver. The touch screen panel is a clear panel attached externally to the monitor that plugs into a serial or Universal Serial Bus (USB) port or a bus card installed inside the computer. The touch screen panel registers touch events and passes these signals to the controller.
The controller then processes the signals and sends the data to the processor. The software driver translates touch events into mouse events.
Drivers can be provided for both Windows and Macintosh operating systems. Internal touch screen kits are available but require professional installation because they must be installed inside the monitor.
HISTORY
In 1971, the first "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor, called the "Elograph," was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens; however, it was a significant milestone in touch screen technology. In 1974, the first true touch screen incorporating a transparent surface was developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented five-wire resistive technology, the most popular touch screen technology in use today. Touchscreens first gained some visibility with the invention of the computer-assisted learning terminal, which came out in 1975 as part of the PLATO project. Touchscreens have subsequently become familiar in everyday life. Companies use touch screens for kiosk systems in retail and tourist settings, point of sale systems, ATMs, and PDAs, where a stylus is sometimes used to manipulate the GUI and to enter data. The popularity of smart phones, PDAs, portable game consoles and many types of information appliances is driving the demand for, and acceptance of, touchscreens.
From 1979–1985, the Fairlight CMI (and Fairlight CMI IIx) was a high-end musical sampling and re-synthesis workstation that utilized light pen technology, with which the user could allocate and manipulate sample and synthesis data, as well as access different menus within its OS by touching the screen with the light pen. The later Fairlight series III models used a graphics tablet in place of the light pen.
The HP-150 from 1983 was one of the world's earliest commercial touchscreen computers. It did not have a touchscreen in the strict sense; instead, it had a 9" Sony Cathode Ray Tube (CRT) surrounded by infrared transmitters and receivers, which detected the position of any non-transparent object on the screen.
Until recently, most consumer touchscreens could only sense one point of contact at a time, and few have had the capability to sense how hard one is touching. This is starting to change with the commercialization of multi-touch technology.
Touch screens are popular in hospitality, and in heavy industry, as well as kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display's content.
Historically, the touch screen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Display manufacturers and chip manufacturers worldwide have acknowledged the trend toward acceptance of touch screens as a highly desirable user interface component and have begun to integrate touch screen functionality into the fundamental design of their products.
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 for your application.
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 has 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 customer’s 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, over20, 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.
