Abstract: A multi-touch surface such as of a touch screen on a platform of an electronic device has a distribution of touch sensitive keys each corresponding to a letter, number, symbol or function. The keys are grouped into pads, each pad being operable by a different one of a user's ten fingertips. The locations of the pads may conform to the shape and size of a user's hands, and to their position and orientation in relation to the screen, and is such that the screen can comfortably be used for typing. Sub-pads may be arranged in proximity to the pads for access by the corresponding finger. A modified version of the key pattern can be used for smaller touch screens.
