The first Dvorak keyboard (and all the variants that appeared afterwise) were designed to avoid wrist injuries by reducing the distance your fingers have to move when typing. Still, movements were still required.
ASETNIOP might be the same philosophy, just one step further: when using it for typing, you do not need to move your fingers anymore.
The basics are that you use only ten input points (feels right: you precisely have ten fingers).
Right, but how would you type an 26-letter alphabet with only ten input keys? Simple enough!
The layout of ASETNIOP consists of eight “primary” keys. Each key primary key represents one of your eight fingers, similar to the “home” keys of a standard keyboard. To obtain the remaining letters of the alphabet, the primary keys are combined into pairs of two to form chords. Based on the eight primary keys, there are a total of 28 chords – 18 of which are used for letters, and a remaining 10 that are assigned to produce commonly used punctuation marks. The thumbs are used as a shift key and a space bar.
The space bar is used only to make the space character, and have no use in chords. The characters are chosen depending on their use. The most commonly used letters are the main keys (no chord required), for instance.
