Finger based metrics

Finger based metrics, as determined with Keyboard Layout Analyzer, using Patrick's original scoring model, and Den's first revised version.

We show the ranking Overall, for the broad Form Factor, and against other similar layouts (Peers), for English prose, assorted Programming, and Average of the two.

'Peers' means compared to other layouts with same characterics, e.g. ANSI/ISO vs Ergo, and matching 'Has letters on thumb', 'Uses AltGr for standard characters', 'Moves non-character keys (ANSI/ISO)', 'Changes shift pairs', 'Changes top row (ANSI/ISO)', and 'Uppercase on different key', as listed above.

Home key bigrams, trigrams, quadgrams and common words

Scores are based on which fingers are used for the top 20 bigrams, trigrams and quadgrams, and top 30 common words, with the scores weighted by strength of finger used, and frequency of occurance of the text.

One-handed words Analysis

This looks at how many words can be typed with only left or right hand. We want these numbers to be low.
This metric was done "strictly" ... shifted or AltGr letters were only included if Shift or AltGr was on the same hand.
Note: we exclude the Dvorak one-handed layouts comparison, since clearly by design they can type every possible word with one hand.

SameFinger Bigrams

This is a weighted analysis of same-finger usage.

The probability that a letter will follow another given letter is used to evaluate layouts by which letters pairs are on the same fingers. We multiply this figure by the percentage frequency of the first letter, in English.
We add the probabilities in both directions, for example "er" and "re".

There are some exceptions: We only look at lower case, and if the second letter is on the same key as the first, we ignore that pair.

The idea is to see how much a finger has to fly around, and if the two letters are on the same key (as in the split-case layouts) then it doesn't have to fly between them.

The metric does not measure how far the finger has to fly, just that it has to. I'll look at adding distance, row jumps, inward rolls, outward rolls, to this metric if possible.

Fraser Street analysis

"Fraser Street" (thanks Shai) is a specially-crafted text in which most of the words are typed with only the left hand, on the QWERTY layout.
It was designed to highlight how much better the Dvorak layout is at hand alternation.
We ignore spaces and punctuation.

Fraser Street was in West Everett. Westward of Fraser Street was the great vast sea. Awed, we gazed seawards, attracted by crested waves which raced and ebbed. Children were scattered on the beach edged and strewed with seaweed. They waded in water as the sea surged in and retreated. They bagged crabs as eagerly as beavers saw trees. Brave crews, seafarers in fact, steered sea craft far away. The site of Fraser Street was not overrated.

Few vegetated in Fraser Street. Nobody wasted time abed. "Acts test the breed," was ever the sacred adage. Varied crafts and trades were represented. There was a caterer, a barber, a weaver, a cabaret, and a garage. Attracted, we started to see several scenes. We were greeted as friends.

The barber catered to a varied trade, representing diverse careers and different creeds. Saturday drew the best crowd. All were seated, relaxed, aware of fewer cares, less fagged. There we saw a few starved tattered beggars who bragged of "bracers" served at cafes after a wee meal of beef stew and cabbage. A better fare was reserved for those reared on earth's greater awards.
