Abstract

An improved keyboard layout for inputting characters displayed on a screen augments the sizes of individual characters relative to each other. The characters are proportionally sized to display more commonly used characters or characters more commonly used as the first character in a collection of characters, or a combination of both types of characters larger relative to less commonly used characters. The shapes of the key display and key sensitive area are sized and shaped to correspond to the end of a human finger so that an operator can chose to input with the left thumb or right thumb, left or right forefinger or both forefingers or both thumbs or using a customized orientation or shape. Less frequently used characters may be reduced in size to accommodate the enlarged characters.
