I recently added a new ability to my anaylzer to load in a different set of monogram and bigram frequencies. This makes it possible to analyze layouts for different languages, in which the letter and bigram frequencies may be differ somewhat from English. You can try this for yourself on my updated layout analyzer, but the results are also summarized here:
Note: to generate these, I used frequency tables for the language in question, but the layout tested is the just the standard Colemak(DH)/Dvorak/Qwerty layout, without the special characters or modifications (QWERTZ/AZERTY/etc) which some of these languages use. So it's not a comprehensive analysis as it might be, but hopefully still a useful indicator.
Layout sf-bigrams score colemak_dh 4.27% 1.714 colemak 4.27% 1.750 dvorak 4.97% 2.015 qwerty 11.83% 2.348
Layout sf-bigrams score colemak_dh 4.98% 1.695 colemak 4.98% 1.759 dvorak 3.49% 1.900 qwerty 9.93% 2.385
Layout sf-bigrams score colemak_dh 3.60% 1.630 colemak 3.60% 1.644 dvorak 3.56% 1.894 qwerty 9.25% 2.348
Layout sf-bigrams score colemak_dh 3.25% 1.655 colemak 3.25% 1.683 dvorak 2.48% 1.889 qwerty 9.65% 2.311
Layout sf-bigrams score colemak_dh 3.80% 1.929 colemak 3.80% 1.948 dvorak 6.82% 2.174 qwerty 9.43% 2.474
Layout sf-bigrams score colemak_dh 4.13% 1.708 colemak 4.13% 1.730 dvorak 4.31% 1.983 qwerty 10.15% 2.316
On this quick test, it's interesting to note that:
- Qwerty is by the far the worst in every language :P
- The language gaining least from Colemak is Polish. French and German gain the most - presumably because these languages are "closer" to English.
- There is a noticeable same-finger penalty in all languages, but at least in Colemak it's always less severe than Qwerty.
- Colemak beats Dvorak in each language, although interestingly, Dvorak has low same-finger for Spanish!
- Mod-DH still comes out the best (of the 4 layouts tested) in each language (yay!)
Those who know some of these languages might be able interpret the results better than I can.
