Abstract: An apparatus and method for arranging a keypad in a wireless terminal, and more particularly, to an apparatus and method for arranging a keypad in a wireless terminal to conveniently perform a key input in the wireless terminal, the apparatus including: a display unit for displaying the keypad in at least one of a right and left side on a screen of the display unit in a horizontal mode of the wireless terminal; and a controller for controlling the display unit to display the keypad in the right and/or left side on the screen of the display unit in the horizontal mode of the wireless terminal.

Abstract: A system for configuring keyboards using both frequency and alphabetical bases, as well as the resulting keyboards. The Keyboard Configuration System uses alphabetized and frequency-based sets of keys. The relevant alphabet is analyzed for letter use on a frequency basis. For maximum-fingers configurations, the frequency-ranked list is broken into rows. Letters are alphabetized horizontally within each row. For minimum-fingers configurations (Personal Digital Assistant keyboards), the frequency-ranked list is broken into columns. Letters are alphabetized vertically within each column. For dominant-fingers configurations, the frequency-ranked list is first broken into rows across six columns. These letters are alphabetized horizontally within each row. The remainder of the frequency-ranked list is then broken into columns. These letters are alphabetized vertically within each column. The resulting keyboards are then evaluated for alphabetical succession relative to the alphabetical direction.

Abstract: A system for configuring keyboards using both frequency and alphabetical bases and the resulting keyboards. The Keyboard Configuration System uses alphabetized frequency-based sets of keys in rows in order to fulfill the requirement that the keyboard must provide a key for each letter of the alphabet. The relevant alphabet is analyzed for letter use on a frequency basis. The frequency-ranked list is then broken into rows according to the number of rows needed for the keyboard. The resulting keyboards are then evaluated for demerits according to alphabetical succession that is backward relative to the alphabetical direction as well as alphabetical succession that is excess forward of zero or one key columns relative to the alphabetical direction. The system set forth here may be adaptable to any written language, especially those based upon phonetic alphabets. Further embodiments include keyboards for PDAs (Personal Digital Assistants).
