Can we first take a step back and look at how your current scoring works?
So that I can understand it, and that any suggestions are in line with the calculations etc.

thanks, Ian

The major difference from Patrick is finger weighted penalty.

For rolls, several factors to consider. Inward vs. outward; in-rolls take minimum effort, and out-rolls is some multiple of that. Also consider which fingers are used to roll. Perhaps a pre-defined array of penalty multipliers; where e.g. ring-index has lowest penalty and ring-pinky has highest penalty.

Then final weight of the roll category. right now, the weights are 33 distance, 33 finger usage, 17 same finger, 17 same hand = 100. Either fit in the rolls on the same scale, which total exceed 100; or rescale everything so they all add up to 100 again.

A matrix keyboard is any board that has straight vertical columns. Including Planck, Kinesis, Ergodox, Maltron. I'm on the Kinesis Advantage2.

The reason for matrix design is mainly to differentiate board designs for purpose of layout analysis, as opposed to de facto staggered design. matrix on KLA is the simplest design that minimizes the penalties from excess lateral movement, and thus yields better scores on these comparison programs. hence I don't bother putting newer BEAKL layouts on other board designs any more.

Nevertheless, you can use BEAKL on any board, and they will still work very well. You can compare BEAKL 32 and BEAKL Opted4 on standard boards with other layouts on the standard board.

My ADNW/Opt config is constantly changing (alas I don't archive older versions). see attached. The latest effort grid (that created BEAKL 8) looks like this:

Code: [Select]
Left hand effort
15   1.5  1    1.5  5
5    0.5  0.5  0.5  1.5
7    2    5    1    7

Other settings are just as important. Be aware if you set them too high, they could overtake the effort grid, reducing its importance.

BEAKL EZ is a solid choice. But BEAKL 8 seems the most ideal BEAKL layout thus far; well, there's also P_RN if you can map that onto your board (I think it works better with smaller thumb keys, like on the Planck). It's more apparent when viewing the heatmaps; look for the home block plus the thumb home. My idea of the home block consists of the top, home, and bottom rows for the ring, middle, and index fingers at the home columns, forming a 3x3 block.

It can't be valid ... it keeps winning. Must be some sort of black magic in there.

Why don't you do JIEA on the left hand?

Index-thumb rolls are not great. thus set to higher penalty in Opt.

what's not valid? I put the alt-gr on the left thumb; so uppercase N & R are typed with alt-gr now.

which i sort of had an idea of treating alt-gr as left shift. which should improve the scores for same finger and same hand, maybe.

counting individual words, and not corpus of prose? because rare words typed on home row don't really matter much. moreover, frequent pinky-ring combos can be just as adverse as off-home-row.

we already have lists of difficult words for analysis.

KLA measures row usage, but doesn't count it for the final score. although i have not verified the accuracy of those stats. since you can customize home row, i haven't looked at the code to see how it counts other rows.

finally fixed the discrepancy for same finger. find the proper way to access the array.

test uses straight scores now; no normalization.

without normalization, scores soar too high on longer text. hard to compare when scores vary so much between different corpus. the key is to normalize against the size of corpus, which is a constant for all layouts.

edit: test uses again normalization that is proportional to text length. now all scores look more reasonable and matches the relative scores as shown in the in-depth charts.

Am trying to see what you are seeing ... but can't... where should I be looking?
I know we asked you about difference between summary page and Misc page, you said summary was standardised....

Normalization was a holdover concept from Patrick when he used percentages as part of the final score. However, we must question if that is correct method since my scoring system doesn't rely on percentages; it's straight up accumulative.

27
What if skip over vowels and type only consonants? Well some cases we still need them, like words starting with vowels or short words. Also helpful to type E if it's final letter.

Fortunately MOK does have "vowel optional" feature. Which works quite well (even though the disclaimer says it's only beta feature.) Since we'll be selecting words from prediction more often, better set to add space after each selection.

Simply move the vowels to the side of the layout, so they are still acessible.

Forgot to upload my vowel-on-the-side layouts. But found something else that resembles it, merely by alphabetical order:



Of course I think mine work better.

The main context is the corpus. For any given text, count the number of times same finger and same hand has been used. So total number of keys pressed shouldn't matter at all.

Something strange always bugged me: Why the final scores for same finger and same hand don't match the results in the misc. table. The most curious was how BEAKL 7 has such low same finger.

The issue is two-fold. One, for some reason, the final scores don't count same finger or same hand if the same key is pressed. This essentially ignores any penalty weighted by finger. e.g. double O or S on the pinky is discounted.

Two, the total keys pressed is taken into account. That gives an advantage to layouts that hit more keys for a given corpus. Instead, the final score coefficient should be consistent across the board for all layouts.

Solution:
  • Count all same finger and same hand pressed, including same key pressed.
  • Use a common coefficient for all layouts on all score categories.

Added to Den3: White layout and several academic text presets. QOL selecting a preset text from drop-down automatically applies it to the textarea.

See for yourself if academic text corpus makes a difference. As far as I can tell, it doesn't affect the ranking at all. The best 5 stays in the top 5.

Unfortunately, White's layout stays in the bottom tier through all tests. It really falls far short from his aim at both prose and code. Frankly it's terrible for either.

he takes the view that the hands should NOT alternate all the time, whereas AFAIK both your and Pat's scoring models want them to alternate.
And he may actually have a point there (eg "the" on an inward roll is clearly better than HE on left and T on right, but what happens with "ETHER" etc. )

But this is a very specific case of trigram and three-finger combo. THE is the only trigram worth considering. Moreover ring-middle-index combo is rare, so it's not viable to fit every common trigrams this way. So do you destroy the health of the rest of the layout just to accommodate one trigram?

Despite that, there has been some claims that splitting all trigrams into 1-23 or 12-3 is best and fastest overall. The same also claims that frequent hand alternation is faster than long sequences using the same hand.

Look at this as a bell-curve of letters typed consecutively on the same hand. i.e. 1-gram, 2-gram, 3-grams, 4-grams, etc. for the same hand. Generally 2-grams are best, then 1-gram, then 3-gram. So frequent hand alternation errs on the side of more 1-gram, avoiding longer grams. On the contrary, low hand alternation leads to slower 3-grams, 4-grams, or worse.

Stumbled across this:
https://github.com/mw8/white_keyboard_layout

However results from Den1 and Den3 against other ANSI layouts.....

Did you properly set the keys to his preferred fingers? like the bottom row doesn't use the pinky for any letter.

At a glance, doesn't look that good. 'R' in the far bottom index. 'OU' typed with same finger. Very high same finger overall.

Some of his reasoning seem flawed. We can assess that in detail later.

There is not much difference between novels, academic, and email texts. They use the same words and letters in similar frequency. Besides, superior layouts can handle them all equally well, and come out on top regardless of what you throw at them--time and time again.

Was playing around a bit earlier with Den3 ... your BEAKL5 does better than BEAKl7. What does Opt say?

Based on my latest configuration in Opt, obviously BEAKL7 is slightly better (~1.6%). That's its purpose--to find the best layout for a set of constraints. On KLA, BEAKL7 slightly loses by (~1.08%). Too close to call which is better.

On KLA, BEAKL5 scores a lot better on distance. Understandably more frequent letters are on the home row; about 5% more usage on home row. However it loses substantially in finger usage and same finger penalty.

OTOH, in Opt, you can set the effort for each key individually. Thus top and bottom row keys can have lower effort scores than home row keys. Also my settings penalize pinky-ring combos even more than ring-ring. Opt takes more factors into account.

So choose your poison. Do you prefer lower finger effort at the expense of distance? Do you care to take the load off the weaker pinky and distribute that load to the stronger fingers?

Hacks / Re: Balanced Keyboard Layout

The advantages of KLA is ease of use and the appealing charts and graphs. As for its scoring, it does a good enough general measurement of key areas that are understood and agreed upon(distance, finger usage, same finger and hand) and to show the trends toward layouts with better efficiency and ergonomics. It also does well to involve the thumb, which some other programs tend to neglect.

As we continue to discover more optimal layouts and reach the plateau of efficiency, that's when we incorporate the minute nuances of typing in order to further differentiate the upper echelon of layouts. Advanced theories like inward rolls (Dvorak), finger weights (Workman, BEAKL), modifiers (Arensito, Seelpy),  etc.

Played around a bit on ANSI. You won't like it because it has the H on the pinky, but I was stuck between my S2 layout and yours... (score around 139 on Den3).
Then I moved the H and got a fright ... some of the metrics are better, some not.

BTW this mod also scores better on Den1, but not as well as S2. (all tests done with Alice only)
So Den3 scoring model clearly a different kettle of fish. I've finished running all the tests on Patrick's and Den1 scoring, need to do the whole exercise again with Den3 ... is it now considered stable, or are you still tweaking?

Main issue is KLA is too simplistic, compared to other analyzers--like Opt. It doesn't consider stuff like trigrams, finger-pair weights (e.g. pinky-ring is bad), individual key weight, finger percentage, hand balance, etc.

So I'm wary of tweaking layouts from Opt just to get screaming scores on KLA.

Read other peoples' thoughts on finger weights. Some treat top-row middle and ring fingers as extended home row, because of natural curvature of the hands. Some don't mind stretching index to middle columns; ultimately still not as good as bottom and top row index.

Anyway, retweaked Opt, and got this:

Code: [Select]
jhau, gmrpz
qoeiy dstnb
/k'.x wclfv

(on Den 3) Higher distance offset by both lower finger usage and same -finger repetition.

Even lower usage on pinky (yay!). Less than 1% typed by the left pinky. H now on top ring; needs getting used to, particularly HE bigram, but any ring finger key is really faster than even home pinky. OEI on home row feels more Dvorak. Now left ring finger will do more work for OH, both common letters.

As for consonant district, this has reduced same finger usage (on Den 3) than previous BEAKL layouts. Interestingly, GMP/WCF are interchangeable between top and bottom rows. I prefer G on top row--NG rolls feel better like this. MP/CF tend to appear on the same row. C on bottom is slightly more comfortable, rolling together with N and T.

Den 3 puts much more emphasis on finger weights. especially punishes pinkies. Finger usages also more relevant; closer to distance scores.
