A variety of methods and systems for presenting and delivering user application input choices. One-handed or vocal user input provides chords or syllables. The invention includes systems and methods for presenting user application input choices, chord or syllable based apparatus and sub-systems for generating user application input choices in response to input signals associated with chords or syllables. One embodiment of input device resembles a joystick and includes a base and a key carrier extending from the base. A single key is provided along the top of the carrier, and four keys extend widthwise along a side surface. A system presents and delivers user application input choices. An input device receives chords and syllables. A processor associated with the input device receives chords or syllables and generates input signals, a second processor for receiving and evaluating the input signals and for sending a user application signal to the user application processor of the computer.
