This deals with the new technology named ?Touch Screen?. By this, technology the purpose means just in the name touch the screen and activate instructions. Instead of the keyboard or mouse we can operate or stimulate an instruction or command by touching on the screen by our finger.And through this seminar and presentation trying to explain about the touch screen, the advantages and major marketing areas where the touch screens used and some applications.This technology is nothing but software with CPU like hardware and touch screen technology digital camera. This technology will obviously bring much developments in the e-commerce sector.

The benefit of using such kiosks is to bring down human efforts and to increase the customer services. The future development of wide area networks based on ISDN will permit retailers to update their kiosks on a regular basis over night if necessary. Customers will be able to carry out an increasing range of transactions using smart Cables and Satalite as well as telephone lines, can be used to deliver information and retail services to the home.

TOUCH SCREEN TECHNOLOGY


.pptx   TOUCH SCREEN TECHNOLOGY.pptx (Size: 498.53 KB / Downloads: 37)
INTRODUCTION

Works with the principle of CRT (Cathode Ray Tube) technology
Input device --> Operates a PC by simply touching the display screen.
Made of sensitive glass overlay & desired inputs can be given by touching it.
Inputs --> External (light pen) or an internal device (touch overlay and controller) .

TOUCH SENSORS

Touch sensor --> In between clear glass panels.
Responsive area --> Entire viewable area of the display screen.
Sensors --> Detects electrical current or signal.
Touching -->causes a voltage or signal change, thereby the location can be determined.

SOFTWARE DRIVER

Acts as a bridge --> Screen and processor.
Makes the operating system --> To interpret the touch event information.
Touch screen drivers today --> Mouse-emulation type driver ( like touching the screen the same as clicking mouse)
Recent research --> To make it as PNP

RESISTIVE TOUCH SCREENS

1. Polyester Film.
2. Top Resistive Layer.
3. Conductive Transparent Metal Coating.
4. Bottom Resistive Layer
5. Insulating Dots .
6. Glass Substrate

WORKING OF RESISTIVE SENSORS

Resistive touch screen monitor composed of :
Flexible top layer
Rigid bottom layer
Insulating dots
Along with touch screen controller.
Top & Bottom layers --> transparent metal oxide coating.
Pressure over the flexible top sheet --> Makes electrical contact between the resistive layers & the switch closing in the circuit.
Controller --> Alternating voltages & converts them into the digital X and Y coordinates.

WORKING OF SURFACE WAVE SENSORS

Contains Transmitting and receiving transducers
Touchscreen controller --> 5 MHz electrical signal to the transmitting transducer.
Converts electrical signal --> ultrasonic waves within the glass.
Waves --> Directed across the front surface of screen.
Reflectors - -> Reflects & directs towards receiving transducer.
Receiving transducer --> reconverts --> An electrical signal & digitally maps the touchscreen.
