Although the implementation of touch screen technology was meant to improve the user experience by providing a more intuitive method of inputting commands, there are a series of problems with the idea. This is less apparent in devices such as a touch screen laptop tablet where the user might carry the tablet pc in their arms while tapping the screen with a stylus. But in applications such as an information kiosk, automated teller machine, or other devices where the user must raise their palms to the screen muscle exhaustion is a very real limitation.

The supposedly most intuitive tools we have to transfer commands to a computer are our fingers and a pen or stylus. However, the problem with that is such that the small muscles in our fingers are not designed to be flexed in a rigid position for extended periods of time. Keeping the arms in a raised position can quickly tire the muscles and joints such as the elbow and shoulder.

Another common problem with touch screen does not involve the stamina of the user but the screen’s ability to accurately distinguish and render intentional from unintentional contact with the screen. The improvements made to popular commercial devices such as the Toshiba touch screen laptop has allowed the user to quickly and effective work with the touch screen with minimal touch recognition problems.

Different touch systems have drastically affected the quality of the screen display by reducing the brightness levels. But with newer screens there is minimal to no reduction in screen brightness. With the reading precision improves so has to quality of the display making these computers very powerful portable multi-media devices. It is just a matter of tweaking some imperfections and, as evident by the recent rise in popularity of touch screen computers, the public is more than eager to accept this as the interface of choice.
