INTRODUCTION TO TOUCHSCREEN TECHNOLOGY  Touchscreen allows the user to interact directly to the interface displayed over the monitor, rather than indirectly with a cursor controlled by a mouse or touchpad. Such interface navigation does not require any intermediate device that would need to be held in the hand. Touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device. A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with a special stylus/pen and-or one or more fingers. Touchscreens are common in devices such as game consoles, personal computers, tablet computers, and smartphones.

Recent Advancement of Touchscreen Technologies  Although the underlying technology behind touchscreens can be traced back to the 1940s, there's plenty of evidence that suggests touchscreens weren't feasible until at least Recently, with the plethora of new UI developments, such as drag, move, zoom in/out, rotation, etc., input has become easier, and the development of multi-touch technology has allowed people to work simultaneously on one display device. But many upcoming advances may make touchscreens even easier to use, and thus even more common in devices you use every day.  Tactile Feedback: you won’t have to rely on visual cues from your phone or computer, this technology will be able to differentiate touches and change the overall user experience. Soon, It will be able to differentiate textures and simulate actual computer or phone keyboards to show the difference from one key to another. It will have a major benefit for touchscreens on dashboards and consoles inside automobiles.

 Dual Screen: Products with touchscreen capabilities also often offer the technology on dual screens. The Acer Iconia is a small netbook that offers a full touchscreen experience where Web pages can flow from one screen to another. It also uses gesture memory to track movements to open Web sites or apps when it recognizes the movement  Optical touchscreens are a relatively modern development in touchscreen technology, in which two or more image sensors are placed around the edges (mostly the corners) of the screen. Infrared back lights are placed in the camera's field of view on the other side of the screen. A touch shows up as a shadow and each pair of cameras can then be pinpointed to locate the touch or even measure the size of the touching object  The development of multipoint touchscreens facilitated the tracking of more than one finger on the screen; thus, operations that require more than one finger are possible. These devices also allow multiple users to interact with the touchscreen simultaneously.  In the future, third-generation display technology will be able to deliver emotions, taste, and smell.

APPLICATION OF TOUCH SCREEN TECHNOLOGY  Museums: touchscreens are popular in heavy industry and in other situations, such as museum displays or room automation  Library resource guide, Corporate information  The popularity of smart phones, ATMs, and many types of information appliances is driving the demand for touchscreens  Airport terminal passenger internet and s systems  Digital jukeboxes  Computerized gaming: many games use the touchscreen as a primary controlling device  Student registration systems

 Intuitively easy to use.  It is so direct. Using your fingers or a pen is very hands on, and manipulating objects on the screen is very similar to manipulating them in the manual world.  Functions for touch screen devices are novice oriented.  Improved experience – Touchscreens provide end users an opportunity to interact with the computer, improving the human-computer interface and improving the user’s experience. The device provides a pleasurable experience for the end user secondary to the intuitive touchscreen interface.  Easy access – Touchscreens provide an easy to understand, intuitive interface for the human brain. Touch is a natural way for us to interact with the world around us and pointing at something with our finger is as natural as breathing air.  It saves time ADVANTAGES OF TOUCH SCREEN TECHNOLOGY

DISADVANTAGES OF TOUCH SCREEN TECHNOLOGY One has to look to touch or requires full attention when making use of it. Touch screen devices have mostly low battery life. Mostly touch screen devices means screen cannot be read too well in direct sunlight. Touch screen devices usually have no additional keys such as end keys. For instance, when your device or an application crashes, you are not able to return to the main menu since the screen becomes unresponsive. The screen can get dirty easily from finger prints and sweat. Mostly touch screen devices such as laptops and cell phones are fragile.

CONCLUSION  A remarkable feature of touch screens that is evident with our present technology is being able to shift forward or backward from one image to another by a touch of the image and quickly sliding the finger left or right on the screen. These were just some of the important innovations of touch screen technology and thus, paved the way for its continued advancements. What has then been started years ago has prompted every complex developments of the present, extending its influence to the future  Meanwhile, your phone buttons, keyboard, mouse and other electronics are increasingly becoming the leftovers of a past generation. Today a larger share of the population is PC literate unlike the past, yet the touchscreen has become adopted by computer users of all abilities because of the benefits attained. In the future, the usage of mouse and keyboards would have been a thing of the past because touchscreen would replace it
