Vaguely reminds me of Dave Mackay's (sadly now neglected) Dasher research project[1], in that both can be used to enter text with input devices that only have a single axis.
Dasher's seems like it fits better with continuous/'analogue' input methods, though (it uses inherently continuous input, Minuum's just using the analogue entry systems to simulate a single-row keyboard).
