Using Piano to Type Text
Of my 10+ years obsession studying keyboard efficiency, including steno, i think nothnig beats using piano for typing.
Inspired by the high keying rates of skilled pianists, we study the design of piano keyboards for rapid text entry. We review the qualities of the piano as an input device, observing four design opportunities: (1) chords, (2) redundancy (more keys than letters in English), (3) the transfer of musical skill and (4) optional sound feedback. Although some have been utilized in previous text entry methods, our goal is to exploit all four in a single design. We present PianoText, a computationally designed mapping that assigns letter sequences of English to frequent note transitions of music. It allows fast text entry on any MIDI-enabled keyboard and was evaluated in two transcription typing studies. Both show an achievable rate of over 80 words per minute. This parallels the rates of expert Qwerty typists and doubles that of a previous piano-based design from the 19th century. We also design PianoText-Mini, which allows for comparable performance in a portable form factor. Informed by the studies, we estimate the upper bound of typing performance, draw implications to other text entry methods, and critically discuss outstanding design challenges.
The learning time required to achieve 80 word per minute is less than learning touch-type on QWERTY keyboard.
And, the learning time to achieve 200 wpm seems comparable to Stenotype Machine.
