ABSTRACT:
A method and device for improved character input are described, wherein the method employs a keypad100comprising keys102able to display secondary characters106in addition to primary characters104.The keypad has a default display state. A first key selection causes the keypad100to display secondary characters106associated with the first key on other keys102,whereupon a second key selection causes the displayed character to be input, following which the keypad reverts to displaying the default state. Further secondary characters200may also be displayed after a first key selection. The method is particularly useful for handheld devices such as mobile radio telephones or handheld computers adapted to implement the method of the invention.
