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 page 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 SCREEN 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.
The touch screen is one of the easiest to use and most intuitive of all PC interface of choices fro a wide variety of applications. A touch interface to allows users to navigate a computer system by touching icon or links on the screen.
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.
