Are touch screens accessible?

 A touch screen is a computer display screen that is sensitive to human touch and allows a user to interact with the computer by touching the screen. In fact, touch screens have been used as assistive technology for many years, providing an alternative to standard input devices for users who need access to standard applications. Specially designed applications have also been developed specifically for touch screen use. These applications typically include large icons and a simple intuitive design layout. 

Touch screens today are frequently used in our daily life, for example in ATMs, ticket terminals, infokiosks and customer self-service stations in retail stores. In the field of education, touch screen stations are being installed in corporate learning environments to facilitate interaction between the learner and the content to be learned. In elementary schools, students who don't have keyboard and mouse skills can use touch screens to access rich computer-based content. Researchers are actively exploring ways to integrate touch screens more fully into educational environments, such as building touch screen functionality into walls, student desks, and other objects in the learning environment. 
Advantages of touch screen are visible and uncountable. The use of touch screen provides user a chance to have more desk space, since you are not required to hook up a standard keyboard and mouse. It also reduces the number of separate components that may eventually need replacement - there is no need to worry about needing to replace the keyboard or mouse due to careless customers or employees. 
Furthermore, it is much faster to click something using your finger or a stylus pen than it is to move a mouse or keyboard arrows. Speed can make a huge difference while playing a fast-paced game. Speed also can be significant for placing orders in your business. Also for beginning computer users, using a touch-screen monitor is easy and less intimidating. 
Another of the advantages to using touch screen technology is its adaptability, both in terms of hardware and software. Manufacturers can produce hard glass or soft plastic touch screens, ranging from simple two-color Liquid Crystal Displays (LCD) to large colour CRT-based units. Also, developers can adapt this technology to work with existing software by using on-screen keyboards and allowing taps on the screen to emulate mouse clicks. 
There are several common types of the touch screen: resistive, infrared, acoustic (SAW) and capacitive. The KeeTouch offers a wide range of sensor screens with different specifications and functions. One of the most popular and useful functions is a multi-touch. 
While touch sensing is commonplace for single points of contact, multi-touch sensing enables a user to interact with a system with more than one finger at a time, as in chording and bi-manual operations. Such sensing devices are inherently also able to accommodate multiple users simultaneously, which is especially useful for larger interaction scenarios such as interactive walls and tabletops. The multi-touch sense feature also enables the pinch-to-zoom feature when zooming in on a photo or other mediums.
