Query: Enabling Input on Tiny/Headless Systems Using Morse Code   This paper presents results of a pilot study that explored the potential of
Morse code as a method for text entry on mobile devices. In the study,
participants without prior experience with Morse code reached 6.7 wpm with a
Morse code keyboard in three short sessions. Learning was observed both in
terms of text entry speed and accuracy, which suggests that the overall
performance of the keyboard is likely to improve with practice.
