===Abstract===
Touch screen have exploded into the consumer technology market over the past few years and aims at replacing the traditional input device like mouse and keyboard. This new technology allows users to operate a technological device in a more natural way. However, touch screen technology have inherited drawbacks that have “sub-consciously” been solved in other less intuitive methods of input, such as low haptic feedback. These problems could be partially overcome by implementing vibrations or audio feedback to help provide a better feel.
===Conclusion===
Touchscreen technology allows for the most natural computer-human interaction in which users can exactly where they want to interact without the use of a middleware such as a keyboard or mouse. This technology has a low learning curve because humans know instinctively on how "touching" works. However this technology faces difficulty issues in order for it to be widely accepted. First of all, touch screen typing has not been widely accepted because of key size, especially on smartphones, and the difficulty of knowing which key was pressed. The fundamental flaw with touchscreen technology is the lack of haptic feedback. Without haptic feedback, users have no way to ensure that the appropriate key was pressed without an action happening on screen. Even with these drawbacks, touchscreen popularity will increase with the increasing popularity of smartphones.
