Distribution of keystrokes when typing with an "invisible" keyboard using ASETNIOP
The ASETNIOP chorded keyboard concept consists of ten input points (one for each finger/thumb) for most frequently used letters, and combination input for the remainder
The ASETNIOP key chart may look a little complicated, but it's been designed with the QWERTY touch typist in mind
ASETNIOP primary keys can be up to eight times larger than letter keys on a tablet's virtual keyboard
For the touch typist, the tablet and smartphone experience is often a frustrating one. While it is possible to key in characters without looking at the virtual keyboard, efficiency and accuracy are a whole lot easier to achieve with physical points of reference. Tactile overlays like the TouchFire can help, but you still lose at least half the screen to the keyboard. Wireless keyboards are a much safer bet but add bulk to the travel pouch. Zack Dennis has developed a virtual keyboard replacement called ASETNIOP which can be made invisible, is based on the QWERTY layout and allows for input using only ten touch points.
