ASETNIOP is a keyboard replacement method that provides the full functionality of an entire keyboard using only ten keys. In ASETNIOP, the most common letter pressed by each finger on a traditional QWERTY keyboard (A, S, E, T, N, I, O, and P) is assigned to each of the eight "home" keys. The shift and space keys are assigned to the thumbs. All other letters in the alphabet, as well as punctuation, numbers, symbols, and other function keys, are produced by pressing "chords" of two or more keys at once.
ASETNIOP is designed to make touch-typing possible on any device that can be configured to have ten active keys. Currently, this includes touchscreen tablets and traditional keyboards, but in the future ASETNIOP will serve as the foundation for typing with emerging technologies like gesture recognition, wearables, and touch-sensitive surfaces. The principle of having exactly ten keys, with one finger assigned specifically to each, ensures that ASETNIOP will remain practical even as input systems continue to evolve.
ASETNIOP includes useful features like word predictions, autocorrect, and stenographic combinations, and once proficiency is attained typing speeds of over 100 words per minute are possible. Language modules are available for English, German, Spanish, French, Italian, Dutch, Norwegian, Polish, Portuguese, Romanian, Swedish, and Turkish, with more forthcoming. Alternate layouts are available for Dvorak and Colemak users.
