Touch technology has been developed since the nineteen seventies by Fairlight CMI and in the nineties by corporations such as Sony, GVC etc In more recent years, touch technology has become more mainstream and is distributed by companies such as Dell, Acer, Iiyama and Compaq. Touch screen technologies such as GVC tech, can be found in many installations and applications such as ATM machines, ticket dispensing machines, information points, industrial, design and commercial office environments. These monitors provide the perfect all in one input and output device. Our Sentios standard units can be used as EPOS devices in retail, although specialized units can be supplied.  Touch screen monitors are used extensively in schools and universities with educational and learning software. Other applications include the automated control of CNC, Automotive, Robotic Manufacturing and many other industrial applications.  Please contact Sentios for further touch product specifications and more information on how these devices can be used. Additionally, in many production and manufacturing settings, touchscreen devices are mounted on walls to enable workers to be able to clock in and clock out quickly and easily. Intuitive screen applications make the use of interactive monitor devices in any use intuitive and easy to use. There are nine possible touch screen monitor technologies available, but in the majority of cases, the more commonly used touch technologies are resistive, capacitive, optical infra red, and SAW surface acoustic wave.

Resistive
Resistive technology is commonly used in portable gaming console units such as Nintendo DS and 3DS. Resistive touch screen displays work through a matrix of sensors mounted on separated membranes which connect and therefore conduct upon contact. Because of this, resistive touchscreen work well with gloves or a stylus. Mobile point of sale terminals often use the same resistive screen tech and are becoming increasingly popular with courier companies who use these devices when obtain electronic customer signatures to confirm receipt of goods. Resistive touch screen monitors screens offer more value and are a lower cost benefit option for users but can be limited. Resistive touch screen displays are more venerable thank other more robust options due to the fact that the resistive membranes sit on top of the glass. For outdoor applications, this would be a less attractive option as the resistive membrane can be easily cut with a knife or other sharp implement. Additionally, in certain poor light conditions, the resistive membranes may obscure the clarity of the rendered image. Because resistive interactive monitors and screens rely on pressure for  activation, over time they have a tendency to wear down and degrade. This also makes this type of technology less suitable for high transaction and heavy usage applications such as public access touch display devices.

Capacitive
Capacitive touch screen technology has become more popular in recent years due to its use in Apple devices such as the iPhone, iPod, iPad and other smartphone and table interactive devices. Capacitive touchscreen technology relies on the conductivity of its users fingers detected by piezoelectric transducers placed in the four corners of the touch screen display. As the users fingers move across the screen the piezoelectric sensors detect capacitive drops and changes This presents an immediate drawback for certain uses such as with gloves, a stylus or other pointing device, however specially designed capacitive stylus pen can be used as a conductive device to interact with capacitive screens. Capacitive sensing is based upon capacitive coupling technology which is utilised in other interactive ancillary devices such as mice, touch pads and other input devices. Capacitive interactive technology can also be used in more advances multi touch gesture monitor displays, and also in through glass touch technology, enabling a range of interactivity through ordinary sheets of glass such as in shop window displays.

Optical IR
Infra red screens work either by heat or light sensor technology. A heat sensor infra-red touch screen monitor can be used with a gloved hand, a pointer or stylus. The light sensor infra-red tech broadcasts invisible light beams across the surface of the screen and is constantly monitoring the X and Y for a break in the beams. Infrared touch solutions are often more expensive and tend to be found more in high-end industrial applications. Infrared touchscreen units can also be found in outdoor installations and point of sale devices which do not need to rely on conductive contact for interaction and input. As with capacitive, infra-red screens offer more clarity than resistive because there is no membrane or touch sensor matrix through which the user views the image.

SAW
Surface Acoustic Wave touch screen technology presents a more accurate option. Piezoelectric radiators emit sound waves which are rebounded by SAW deflectors. This spreads surface acoustic waves across the entire surface of the glass screen. When an SAW touch screen monitor is contacted by a finger, part of the acoustic wave energy is absorbed. The changes are detected by sensors which communicate with the control logic which determines the position of the contact point. Surface acoustic wave screens and monitors may malfunction if exposed to vibration or external acoustic noise and may not be as accurate as capacitive or resistive screen technology. Advantages of SAW touch-screens are that they can be made durable making them ideal for rugged outdoor use. Because there is no visible element to the technology, the touch screen sensing technology does not impede the interactive display image quality. An SAW specific stylus pen is available for use on these systems by using a rubber tip which disturbs the emitted acoustic wave.
