ABSTRACT:
A method and device designed to improve the speed, accuracy, and ease of entry of characters and other symbols by a user. The device is designed to use a reduced size input area as an input source and optionally as a display screen. A set of characters or other symbols is divided into subsets, each subset being represented by a control button for display on the reduced size input area for user selection. A user's selection of a control button produces a secondary set of buttons representing the characters or other symbols in the selected subset for user selection, storage, and display.
