In our search for faster text-entry systems, we were inspired by the high keying rates of skilled pianists, which are more than twice as fast as typists. We developed PianoText, which allows text entry on any MIDI-enabled piano keyboard. A computationally designed mapping assigns letter sequences of English to frequent note transitions in music, based on four concepts: redundancy, chords, sound feedback, and skill transfer. Our studies show text-entry rates of over 80 wpm and we estimate expert performance rates of 130-160 wpm. Our findings on those studies will inform the design of faster text-entry systems.
