Rob Speer came up with the following proposal for a Lojban Dvorak keyboard:

English Dvorak:

' , . P Y F G C R L / =

A O E U I D H T N S -

Q J K X B M W V Z

Lojban Dvorak:

/ - Y P J R K C D , =

A O E U I L ' T N S .

Q H Z G X B M F V W

Discussion

  • Is Rob's keyboard just trying to minimally rearrange the Dvorak to suit Lojbanists, or is it a true attempt to implement a layout in the Dvorak style that statistically suits Lojban as Dvorak suits English?
    • Rob Speer:
      I'm trying to minimally rearrange the Dvorak. It would take much more effort to actually redo Dvorak's research using Lojban heuristics, and ideally if I typed enough in Lojban to want to use this, I'd want it to be easy to switch from Dvorak.
      • Adam:
        If you really wanted to redo Dvorak's research for Lojban, and presumably were willing to relearn how to touch type and come up with a keyboard driver which would implement your keyboard, you could use a genetic algorithm and a very large Lojban corpus: http://www.visi.com/~pmk/evolved.html
  • Why are you favoring the slash and semicolon?
    • Rob Speer
      I didn't think of it as favoring at the time, but I suppose the keys up there are easier to get to. Very well then - this lets me change from Dvorak even less.

, . Y P J R K C D / =

A O E U I L ' T N S -

Q H Z G X B M F V W

  • Incidentally, what are the most frequent letters for Lojban gismu (this is an apparently moot issue for the cmavo, as all combinations seem to have been exhausted)? They wouldn't be the same as English. Are the consonants fairly evenly distributed, or is there a most common one that can take the place of the T? Furthermore, should we count freq. by words it's in, or by frequency in actual use? The former is easier to measure, the latter makes for better keyboard designs.
    • la gejyspa:
      The most common letter in gismu is r. Oddly, though, it's not the most common letter in any given position, which are: s-a-n-n-i, in that order. Restricting ourselves to CCVCV gismu, only, that becomes s-r-a-n-i.
  • So I downloaded the keyboard-evolver code, and seeded it with Dvorak, QWERTY, and my layout above.
    So much for my big ideas - my layout only slightly better than Dvorak in the first round.

Other names

jokingly called "QwertAsdf" (QwertAsdf is when you type "Qwert", followed by "Asdf".)

It's also what happens when a clueless newbie stumbles upon a WikiWikiWeb and can't resist trying to add a page, for whatever stupid reason.
