An ABCDE... keyboard for mobile devices

UniTap - technology for the most compact alphanumeric keypad for mobile devices - yet another take on how to get decent input into small devices.

Tries to take advantage of the fact that fingers are too big to hit small keys by requiring you to hit the buttons which are all round the target area (and the target area itself isn't a button). There's no real reason why you couldn't do this with a touchscreen, surely, and then have it available for other display purposes too - unless you get better feedback that the "key" has been pressed from the buttons.

I don't agree with their blurb that it's intuitive - "No difference from operating with regular computer keyboard" - anyone who's used a Psion Workabout for more than a few seconds will tell you that an ABCDE... mapped keyboard is not intuitive to someone used to a QWERTY one, but I expect it'd only be as difficult to learn as a phone keypad is at first.
