Tablet Computer - Touch User Interface

Touch User Interface

A key and common component among tablet computers is touch input. This allows the user to navigate easily and intuitively and type with a virtual keyboard on the screen. The first tablet to do this was the GRiDPad by GRiD Systems Corporation; the tablet featured both a stylus,a pen-like tool to aid with precision in a touchscreen device as well as an on-screen keyboard.

The event processing of the operating system must respond to touches rather than clicks of a keyboard or mouse, which allows integrated hand-eye operation, a natural part of the somatosensory system. Although the device implementation differs from more traditional PCs or laptops, tablets are disrupting the current vendor sales by weakening traditional laptop PC sales in favor of the current tablet computers. This is even more true of the "finger-driven multi-touch" interface of the more recent tablet computers, which often emulate the way actual objects behave.
