In laptop and other mobile PC designs the integrated keyboard is always a critical piece. Keyboards drive
much of the laptop size because it covers most of the system. The size cannot be reduced much without
impacting the user experience. Key size and spacing need to be sufficient for the user to type
comfortably and maintain muscle memory. The function row on the top of the keyboard, used for
function and shortcut keys, is usually smaller in vertical size because they are rarely pressed, but very
much required for quick access buttons. They can be moved to the bottom of the touch screen and
appear and function only when necessary. Tactility is not as important for function keys because they
are rarely pressed without the user looking at it. Integrated Keyboards size and weight can be reduced
by this design as well as provide unlimited customizability of the function keys.
