A software multi-tap input method requires only two taps to input most characters. This is especially beneficial for languages where existing multi-tap methods require on average more than two strokes per character, and where handwriting recognition is currently an unacceptable alternative. The described system employs a touch-screen input that contains a selection of displayed "buttons" substantially fewer in number than the number of potential characters in the language of interest. An input area contains an array of symbols, each symbol being associated with a group of candidate characters. A candidate area contains an array of characters associated with a most recently selected group symbol in the input area. To select a particular character, a user pushes a group symbol in the input area and then selects the desired character in the candidate area.
