Touch Technology

It doesn’t take a rocket scientist to figure out that the biggest trend in the cell phone world today is the touch screen. Have you ever thought how this wonderful touch screen technology works out by a mere touch of a finger? Let’s get in touch with the touch technology.

PUT YOUR FINGER ON THE ‘TOUCH TECHNOLOGY’

A touch screen is basically a technology that ensures a more visually pleasing computing experience by skipping the middleman (Mouse, keypad etc) and giving the digital life abilities to your fingers. Touch screens provide an alternative user-interface to the historical mouse and keyboard of traditional computers. Touch screens are found in ATMs, PDAs, cellular phones, grocery checkout counters, airport check-in counters, and many other devices that we use every day. Touch screen is also an input device. The screens are sensitive to the lightest touch and the user interacts with the computer by touching pictures or words on the screen.
This was a short description on what is basically a touch screen …now let’s move on to the technological part of it …..What actually makes it happen…
The touch panels themselves are based around four basic screen technologies: Resistive, Capacitive, Infrared (IR), and Surface Acoustical Wave (SAW).

Resistive Touch Screen Technology

As the term denotes Resistive or Analog resistive touch screen is a sensor consisting of two opposing layers, each coated with a transparent resistive material called indium tin oxide (ITO).The ITO used has a typical sheet resistivity between 100 and 500 ohms per square. The layers are separated by a pattern of very small transparent insulating dots. Silver ink bus bars (~50mW/sq) make an electrical connection to the surface of the ITO at the outside edges, spanning the desired axis of the given layer. Silver ink traces (~50mW/sq) connect the bus bars to an electromechanical connector used for interfacing to the sensor. The cover sheet has a hard, durable coating on the outer side, and a conductive coating on the inner side. When touched, the conductive coating makes electrical contact with the coating on the glass, and a touch is registered by the analog controller. Offering excellent durability and resolution, resistive technology is used in a variety of applications and environments.Resistive touch screens deliver cost-effective, consistent and durable performance in environments where equipment must stand up to contaminants and liquids, such as in restaurants, factories, and hospitals. Disadvantages of Resistive technology include only 75% optical transparency and the fact that a sharp object can damage the resistive layers.The Analog Resistive technology is perfect for PDAs, web phones, and other handheld consumer applications.

Capacitive Touch Screen Technology
The touchpad contains a two-layer grid of electrodes that are connected to a sophisticated full-custom mixed signal integrated circuit (IC) mounted on the reverse side of the pad. The upper layer contains vertical electrode strips while the lower layer is composed of horizontal electrode strips. The IC measures "Mutual capacitance" from each of the horizontal electrodes to each of the vertical electrodes. A human finger near the intersection of two electrodes modifies the mutual capacitance between them, since a finger has very different dielectric properties than air. When a user touches the screen, some of the charge is transferred to the user, and makes the potential difference on the screen. After the panel controller recognizes that, the controller will send the X-Y axis information to the PC port.

The advantage is that capacitive technology transmits almost 90% percent of the light from the screen. The superior efficiency gives capacitive better than resistive technology.

Surface Acoustic Wave (SAW) Technology

The Surface Acoustic Wave (SAW) technology is one of the most advanced touch screen types. The technology is based on two transducers (transmitting and receiving) placed for the both of X and Y axis on the touch panel. The other important element of SAW is placed on the glass, called reflector. The controller sends electrical signal to the transmitting transducer, and transducer converts the signal into ultrasonic waves and emits to reflectors that are lined up along the edge of the panel. After reflectors refract waves to the receiving transducers, the receiving transducer converts the waves into an electrical signal and sends back to the controller.

Compared to Resistive and Capacitive technologies, SAW technology provides superior image clarity, resolution, and higher light transmission. Because the panel is all glass, there are no layers that can be worn, giving this technology the highest durability factor and also the highest clarity. Disadvantages of Surface Acoustic Wave (SAW) technology include the facts that the touch screen must be touched by finger, gloved hand, or soft-tip stylus (something hard like a pen won't work) and that the touch screen is not completely sealable, can be affected by large amounts of dirt, dust, and / or water in the environment.

The Surface Acoustic Wave technology is recommended for ATMs, Amusement Parks, Banking and Financial Applications, public information kiosks, computer based training, or other high traffic indoor environments.

Touch Screen Functional Description

Touching the top surface compresses the flexible top layer to the supported bottom layer causing electrical contact of the two layers between the span of insulating dots. Determining a touch location requires two measurements, one to obtain an X-axis coordinate and one to obtain a Y-axis coordinate. A single axis measurement is taken by applying a drive voltage across the ITO of one layer via the silver ink bus bar and trace connections. The voltage applied to this layer produces a voltage gradient across the ITO. The voltage linearly changes from the minimum drive voltage at one end to the maximum drive voltage at the other end. The opposing layer, via a path through its ITO and silver ink connections, is used to measure the voltage at the point of contact on the voltage driven layer. This process is repeated, alternating functions of the two layers to obtain a measurement on the other axis.
Measurements are made using a 10-bit analog to digital converter (ADC). A 10-bit ADC can resolve 2-to-the-10th power or 1024 different input values in each the horizontal and vertical direction. The four-wire system resolution is, however, less than 1024 due to losses in the drive voltage that occur before it reaches the touch screen ITO.
Touch point coordinates are reported to the host computer or microcontroller through a serial communications port.
Touch screens first became a research interest in the second half of the 1960’s. In 1971 Samuel Hurst developed the first “touch sensor.” One of the first places where they gained some visibility was in a computer-assisted learning terminal that came out in 1972 as part of the PLATO project. This was the first step in commercializing touch screen technologies. Touch screens became widely used in kiosk and point of sale systems in banks and stores. In 1983, the first touch screen computer, the HP-150, reached the market. Since then we have seen the introduction of advanced touch screen technologies leading to the commercialization of tablet PCs, PDAs, and touch-screen phones.
Today's mobile phones have been transformed into a multi functional device for imaging, accessing the internet, Music etc. And now the touch screen technology lends it another dimension to give the phone a more heightened interactive experience.
Research firm Strategy Analytics predicts that 40 per cent of mobile phones will incorporate touch sensitive technology by 2012. The latest global study by ABI Research says that more than 100 million handsets with touch screens were shipped in 2008, and over 500 million will be shipped by 2012.
Moreover, every mobile manufacturer today is jumping into the touch screen bandwagon with handsets that are breaking the high price barriers. But, more than the prices it is the new generation of touch screen technologies that are set to make the user experience even more amazing.

MOBILE IMPACT ON INDIAN ECONOMY

Welcome to the ‘WIRELESS-WORLD’ of the mobile phones. The Indian Mobile Market is galloping forward at a wildfire pace giving India’s economy a shift from an agrarian to a service sector. The reason being affordability’ which in turn is further fueling manufacturers and cut-throat competition among the leading mobile phone companies and increasing the entry of private players. Further the various
other factors like rise in the per-capita income, decline in air-time rates, affordable monthly rentals are the other reasons that made it easy for everyone to enjoy the benefits of mobile phones. As per the latest statistics issued by the Delhi based, Telecom regulatory Association of India (TRAI), India has crossed the target of 500 million mobile subscribers (GSM+CDMA) well ahead of the target date of 2010.Let’s have a look on how the mobile phone strikes the Indian economy.
