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 and sub-pads, each pad being operable by a different fingertip of the same hand. The locations of the pads may conform to a user's hand shape, size and position in relation to the screen, and is such that a single hand can comfortably be used for typing. Sub-pads are 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. |
