STANDARD ERGONOMIC LAYOUT KEYBOARD

(draft)

This layout was designed to eliminate the defects of the usual standard computer keyboard layout.

• This standard ergonomic computer keyboard layout has 90 keys (of which 48 are printable character keys).
• The left and right parts of the keyboard are tilted 14° inward from the base (the keyboard can also be manufactured with a slightly variable or variable tilt).

• The image shows the QWERTY layout:

• Staggered column, even more ergonomic and compact variant:

• The SEL keyboard is suitable for desktop and laptop computers.
• The keyboard user must be able to programmatically change keys and save the selected option.

Optional sequences for control keys

• Available options:

  1. SEL Keybord — Fn-F12-F11 + F1 = 1 — (‘Menu’ works by releasing the ‘Control’ button if only one ‘Control’ button is pressed.)
     • Also interesting modification of the first option with exchanged 'Shift' and 'Alt' or 'Cmd' keys.
  2. PC Keyboard — Fn-F12-F11 + F2 = 2
  3. MacOS Keyboard — Fn-F12-F11 + F3 = 3
  4. PC Keyboard mod 2 — Fn-F12-F11 + F4 = 4
  5. PC Keyboard mod 3 — Fn-F12-F11 + F5 = 5 — (‘Menu’ works by releasing the ‘Control’ button if only one ‘Control’ button is pressed.)

SEL Keybord ergonomics

There are three areas in the keyboard: left — for the left hand; right — for the right hand; and the middle is accessible for both hands.

• Different color keys are assigned to each finger:

• The circle of the other color shows the possibility of pressing key by another finger.
