Bill says: "This keyboard works by having each of your ten fingers choosing the character you want by selecting from a radial menu. You can push down, or move north, south, east or west, and get a different character for each. The character you get corresponds pretty well to the character you get with the same finger when you move it from home position on a conventional QWERTY keyboard. The idea is to reduce arm fatigue."





























































Can I just point out that whilst 'digit' is commonly used to refer to numbers it comes from:
late 14c., from L. digitus "f1nger or toe," related to dicere "tell, say, point out" (see diction). Numerical sense is because numerals under ten were counted on f1ngers.

quote, "with one button under each of the five f1ngers and two additional modifier keys for each thumb."
That would mean 5 f1ngers and 1 thumb on each hand. So only people from Norfolk could use this one.
