Features

  1. The wrist-rest is part of the keyboard and is located above the main row keys.
  2. The built-in mouse sensor allows you not to transfer your hand from the keyboard to the mouse.
  3. The thumb keys are located on a separate part of the case, much higher than other keys.
  4. The keys of each finger are located on several circles of different diameters, forming a "stairs". This solution provides maximum perpendicularity of the keystroke vectors to the key surfaces.
  5. Minimum height. The surface of the lowest key is at a distance of 2 cm from the table.
  6. The keycaps are flush with the body.
  7. Replaceable oak pad for resting the wrist.
  8. Reliable russian connector РШ2Н-1-6 for connecting two halves of the keyboard.
  9. Magnets to connect the two halves of the keyboard for transporting.

Layout

Especially for the keyboard, I developed russian layout that provides the maximum frequency of trigrams with rolls and the minimum frequency same finger. English alphabet is mapped with the Russian alphabet by phonetic: а - a, с - s, ш - sh, etc. The A/P-key is used to switch the alphabet.
