Time Bomb

A timer winds down. A hidden random time is chosen. You must stop the timer within 12 ticks (about 4 seconds) before the designated time. If you stop the timer too early or too late, the bomb explodes. A portion of the analog timer is colored red as a hint.

Puzzle Drop

2 panel of tiles: upper, lower. 10x6 each
2 play periods: play 1min ,  rest 30sec

Play period: player stays in lower panel. Items fall gradually starting at top of upper panel onto lower panel and fill each tile. Falling items go pass upper panel items.

Items Like guild wars 2 items: mats, bags, chests,

Player moves between tiles. Must not be buried by items. Stand above items and press key to pick up items. Must not let tiles fill up lower panel.

Lose conditions: Items fall on top of player. Any  Lower panel column  totally filled with items.

Rest period: Items don't fall in this period. Player can go to upper panel. Static bag can be opened to find new bags and Items, which appear instantly at top or lower panel. Player can pick up these Items before rest period ends. Items stay in place for play period.

Tetris Fighter

Tetris blocks fall onto a ledge and bounce to the front. You control a fighter who must attack the blocks before they hit the floor. 3D Ledge closer to player, in front of fighter.

2-way Anti-gravity Tetris

Simultaneously play 2 games of tetris: one game is regular blocks fall down, other game is blocks float up. Control both games at the same time. Press left or right, both blocks move left or right. Press down, the regular game piece falls down. Press up the anti-grav piece fly up.

I've tried to wrap my head around all the layouts here and it has left me quite confused.
Seems like BEAKL 5 Matrix is the way to go if using an Ergodox, right?

BEAKL 5 and BEAKL EZ Matrix are pretty close. BEAKL 5 scores slightly better on KLA, by 1-4%. But it is unconventional by putting some letters outside the main 30-block. If you can tolerate that.

I personally use BEAKL EZ because I like letters inside. But most importantly, it overlaps perfectly with my numpad design, when taking into account the punctuations.

Tech Support / [opera] Opera older versions (Presto)
« on: July 09, 2017, 12:09:45 AM »
Opera 11.x and 12.x still the best browsers ever made, even though it has been discontinued. But nothing can match its configurability, ergonomics, efficiciency, and rendering engine Presto.

Download older versions of Opera, up to 12.x. Highly recommended for any OS, especially older weaker computers and VMs. Even Android--although seems to crash often on newer Android versions--but damn it, no other mobile browser can render webpages as perfect looking as Opera Mobile Classic.

Quick links of Opera 12.x by OS:

Finally created a font file for Flownetic, which I really wanted to showcase in my game.

Using lower and upper case English letters for distinct sounds gives 52 unique sounds. At least 16 letters for distinct vowels. This is much improvement over most alphabets. Unfortunately that only covers 2/3 of the glyphs which I've created for Flownetic so far. Nevertheless, that is good enough for my game for transliteration of English text.

Using thumbs for modifiers seems underutilizing them. Mods take up only 2% of key press. That's about the amount I'd allow for each pinky. That means one of the thumb is only doing as much work as the pinky. (The other thumb is for space, which accounts for 16% key press, which is about the right amount of effort for thumb.)

So mods could be assigned to the fingers. But where? Pinkies are okay if within the main 30 key block; possibly even home pinky. This is perfectly fine if we're putting letters on thumb cluster anyway. (Remember that left one key empty when migrating 3 letters to thumbs.)

Next project for Opt.

Can you maybe clarify that a bit? Not sure I follow.

distance is square root of x+y. but i made it 2x+y to penalize lateral reaching. reasonable to keep?

FWIW I thought you were already counting up+down on all fingers...

will check again later if modifiers are already counted elsewhere.

Revised scoring: Layout Analyzer 2.html

 (old URL with old scoring still work)

- finger usage per character (was per key press)
- penalty for modifier key up (same as modifier key down)
- thumb count as same hand to fingers
- extra distance for lateral movement (x-axis)
- added default layouts (seelpy, maltron)

Scores for finger usage and same hand may be different than before. Over-reliance on thumbs and modifiers (shifts, altrgr) will net higher (worse) score than before.

Be aware these are optimized for inward rolls. So index fingers are where bigrams and trigrams end. So NRE end up on index allows great rolls; and they do feel great. We've seen this before when working on putting letters on thumbs. RN consistently put on thumbs. Also based on my effort chart that doesn't discriminate by rows. Instead focus on home block. So theory and practice meet, creating very comfortable layouts.

R on home row eases combos with other consonants on any row. At expense of worse distance putting N on top; which mainly combo with vowels. IN bigram probably dictates that they go on same row; however AE have priority on home row over I,  Forcing IN to top row.

What if hand alternation is not your thing? That is, you prefer to type longer strings on the same hand. This is candidate layout that Opt spat out:

Compared to Colemak, which also prides itself on long same hand strings. Never typed in Colemak, but did a few sentences to compare with this new layout. Right away can feel Colemak is quite uncomfortable with its finger acrobatics (seesaw) and frequent ring-pinky combos. Don't understand the hype.

On the other hand, this new ZOINX layout feels really good with the rolls and combos. The only flaw is the OU bigram. Overall feels much better than Colemak. Secretly I think it's another success of reducing pinky usage, which naturally leads to fewer ring-pinky awkwardness.

Surprisingly, no matter how much I try to penalize hand alternation, the optimal layouts still end up with vowels on the same hand. For example, below layout has even lower hand alternation, but retains vowel district.

Code: [Select]
jpinz k.dcv
faorm hetsb
q"ulx ',ygw

Well not quite true. This next one has even lower hand alternation. The vowel district is retained for the most part, except E is moved to other hand. (not recommended due to very high same finger.)

Seelpy is different style of typing with different merits than traditional. may be preferred if you like chording or you have health problems that prevent you from reaching keys. (although for full chording, might look into stenotype.)

there is claim that chording is slower than traditional typing:

Arensito is overall great layout for prose with low distance and same finger. its idea for coding is awesome because symbols are common for programmers and who wants to reach all around the keyboard.

some hybrid between seelpy, arensito, and adnw/beakl may or may not work. utilize extra layers, but not as extreme as seelpy with chording. optimizing uppercase still has merit.

the finger weights are not the issue. thumbs are supposed to be preferred to pinkies.

the controversial part is the denominator used to calculate the final score. in particular the finger usage section. to compensate for some layouts might be missing characters, score is normalized for how many keys pressed by that layout. but this assumes typists prefer one key per character.

as denominator, higher value reduces score. ie less effort. so more shifts would actually score better. but this is contradictory if finger usage counts efforts of finger presses but huge amount of presses are ignored in the score.

so correct denominator would not encourage more shifts.

your layouts still score amazing on distance. but should score worse for finger usage and same hand.

Hacks / Re: Balanced Keyboard Layout
« on: May 19, 2017, 01:14:32 PM »
The scoring may also be flawed in that more keys pressed is not punished. Intuitively, more key presses should lead to higher effort scores on finger usage; which is obviously not the case currently. Thus shifting to use two fingers for one character has negligible load on the score.

Is this the desirable outcome? That is, is using two key presses to print a letter more ergonomic than a single key press to reach a more distant key?

Hacks / Re: Balanced Keyboard Layout

KLA counts thumbs as a third hand. so same hand scores will be very low even if you overuse the thumbs and you type consecutively on the same hand between thumb and fingers. When thumbs count as the same hand as other fingers, adjusted scores will offset the lower distance, bringing scores closer to other layouts.

see this section of code in kb.js:

Code: [Select]
KB.finger.leftRightOrThumb = function(finger) {
    switch(finger) {
        case KB.finger.LEFT_PINKY:
        case KB.finger.LEFT_RING:
        case KB.finger.LEFT_MIDDLE:
        case KB.finger.LEFT_INDEX:
            return "left";
        case KB.finger.RIGHT_PINKY:
        case KB.finger.RIGHT_RING:
        case KB.finger.RIGHT_MIDDLE:
        case KB.finger.RIGHT_INDEX:
            return "right";
        case KB.finger.LEFT_THUMB:
        case KB.finger.RIGHT_THUMB:
        return "thumbs";
        case KB.finger.NONE:
            return "none";
        case KB.finger.BOTH_THUMBS:
            return "both";
    return "none";

Another weird thing is the unusually low same finger penalty. Apparently using thumbs can buffer the finger-to-finger combinations. But this is lesser effect on score, whereas same hand has a bigger effect. This is the real reason for the existence of your layout; the essential benefit that is not affected by any scoring algorithm.

Interesting choice. Yeah that t-h worries me, I've tried various things to split them up but so far nothing has worked in terms of improving the score.
I even swapped e with space, which worked for some tests but not others. Part of the problem is the T ... maybe that need to swap to left hand. I've tried moving it to index finger but no real difference, and then you end up with T-h on same finger, not good.

Well actually space -T is also some finger. For that matter, check bigrams that involve space before and after a character.

I checked the numbers... I can't afford it, and I don't see any current manufacturers plonking down large amounts of money for something that will likely never be a big seller. QWERTY is too entrenched (just go ask the Colemak fanboys).

It looks like getting major market coverage will cost about 1 million Rands (about USD 76k at current rates). Then there are yearly renewal fees after that. That's before you even look at cost of manufacturing and marketing etc. I'm guessing Maltron only patented theirs in a few selected countries, and get a licence fee from Kinesis. They probably make more that way than from their own sales.

So yeah, getting rich would be nice, but the deck is stacked against small guys with radical ideas :-)

cheers, Ian

At least post entry to deskthority wiki. Some geekhack users who use advanced layers on ergodox may also appreciate this novel layout.

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.

Nah, made a layout (attached), ran it against the English tests, scores are as per X6.4H +/- <0.5.

So no real improvement, unless my first allocation of Caps sucked.

Here's the frequency lists, I only played with the caps.

Cheers, Ian

What is the frequency of capital letters overall? If they are around punctuations frequency, then rearranging them wouldn't improve much, if at all.

Did you take into account bigrams? to avoid same finger and same hand penalties. e.g. 'M' is almost always followed by a vowel, especially 'e', so you should discourage putting them on the same key. likewise 'Co', 'Is', etc..

I tried using Den's 'costs', with some personal modifications (the 'angleZ' bottom left hand ergo mod popular w. Colemak) with the 'MTGAP' optimizer and I am getting some interesting results.

The original link I had originally followed, that brought me here, had higher pinky costs than the ones we can see on the 1st page of these messages.
In the "Newer thoughts" notes, Den mentions that the pinky costs should be higher .. so I used the costs in the other chart (9 vs 7 for pinky). I was wondering which costs are you actually using !??

Code: [Select]
9   1   1   1   5   5   1   1   1   9
5   0.5 0.5 0.5 2   2   0.5 0.5 0.5 5
9   2   3   1   5   5   1   3   2   9

That chart is good enough for optimizers to find the ideal layout. I messed around with many permutations to see if it makes a difference to finding the best layout. For that matter, little changes to the finger effort costs don't play a big role. Other factors like hand alternation costs drastically affects the final layout.

Nevertheless, a standard chart is useful to compare the exact scores between vastly different layout families. Such as on KLA to compare layouts created by different people and software. But KLA uses a prescriptive scoring system for finger effort not easily visualized in a single chart.

I suspect (without actually having tried it myself, but based on dummy keyboard tests when developing my own designs) that what looks good and obvious in terms of those thumb clusters, is not so practical given the angle that our thumbs operate at. This unsubstantiated opinion (:-)) applies to Maltron and children (Kinesis and ErgoDox). But lots of people swear by those layouts so maybe I'm wrong.. :-)

The problem is the main thumb keys are long, which obstruct the other keys. This is okay for independent utility keys, but not for combination rolling with fingers, especially when speed and accuracy is involved. Big keys also affect the impact point of striking a key. It feels weird to hit a key other than at the center.

Instead, they can split the big keys into smaller keys. This should improve rolling with fingers and provides extra keys for the thumbs.

You use Vivaldi, right? Which is Chromium in disguise... which is (back to roots) based on KHTML. At the moment local versions of KLA do not work in either Chromium or Konqueror (using either of the two supported render engines). The page loads without text. So I thought it was font-related... Firefox say the site uses Lato, pulled in via Google font api. Don't have it installed locally (strangely enough... only Noto family). But I can't figure out why Firefox has no trouble but my other two browsers don't work.

there's something about enabling cross-server scripts for local servers.

If you're going to move the home row on a regular (unergonomic) keyboard, maybe move the whole row up so that the formerly bottom row can be used as thumb row. then put the letters and space on the thumb row as discussed.

We know Arensito moves entire rows up, but it didn't try to put letters on the thumb row. Modified with thumb-letters, Arensito would score much better for text, plus it already scores great on code. That could make it a serious contender.

N on the thumb seems the exception, as all its common bigrams are outward rolls. maybe moving N to thumb would reduce same finger usage. having all three STN on the fingers seems crowded.

Actually P_RN, L_RN and U_RN are even better than I_RN.

Note left top pinky can be left empty. Moving 3 letters to thumb leaves one of the finger keys unused.

Some KLA tests seem to suggest 1-letter-on-thumb (-+T+- HT01-75.54) scores slightly better on regular prose and bigrams/trigrams test than these 3-letters-on-thumb layouts. But sometimes that layout (-+T+- HT01-75.54) does quite poorly on real world texts (social media, random cut-paste). Regardless, these 3-letters-on-thumb layouts score consistently high on all forms of text.

Any theory why H on thumb scores best?

Maybe due to being the most frequent bigrams and trigram. Split the trigram THE. This has 2 consonants and 1 vowel. To balance the rest of the keyboard, 1 consonant--the middle one--is moved to thumb.

moreover Maybe these algorithms don't punish thumb - finger bigrams. I saw something in Opt that penalize thumb - index. But we can assume T E goes on middle finger, which is not affected by this penalty. So it seems middle finger is more premium location than thumb. If E is on thumb, then best place for TH is roll inward. Noting that in some algorithms rolling is less optimal than alternating fingers, especially if alternation involves thumb.

RSTHD uses the same hand for all 3 letters of the trigram most common trigram THE. which works for him since he prefers 2 and 3 keys long sequences.

(notably RSTHD is yet another layout that divides into vowel and consonant districts. also it has space on the vowel side, just like what we've discovered earlier.)

Actually studying my digram chart ( , I think I see (partly) why H works best at thumb instead of other letters. There is a parallel amongst the four most common bigrams, including the space character.


1. The top 4 digrams are made of 4 different characters. So the thumb keys should nominate these as highest priority.

2. H is in the exact same situation as space, relative to T and E.

3. Putting T or E on thumb would imbalance the other bigram. ex. if E is on thumb, then TH must be typed with fingers. conversely, T on thumb means HE is typed with fingers.

4. If H is on thumb, both bigrams score better because thumb is involved for both.

5. Just realized that any finger to thumb is really an inward roll. So if H is on thumb, ideally it should on the same hand as T to make TH an inward roll. on the contrary, HE on the same hand is an outward roll. Same deal with space (instead of H).

6. Once you put more letters on the thumb, H falls out of favor. for instance, 3-letter thumb clusters are optimized for I_RN. see previous post for such a layout:;topicseen#msg835 . (Amazingly vowel and consonant districts are still maintained.) This seems to agree with my assessment that finger-thumb is inward roll. consider bigrams like: ei, ai, oi, tr, pr, dr, fr, gr, cr.

RSTHD scores about 2-6% better than BEAKL EZ on Matrix. We can surmise that letter on thumb has some benefits. However compared to your -+T+- HT01-75.54 layout that puts H on the thumb, RSTHD is about 5% worse. So it still seems our results from Opt for putting H instead of E on thumb is preferred and more optimal.

MSKLC is crap. found Keyboard Layout Manager instead:

Stumbled across this:

Layout is 'curious' given that it was evolved. Initial testing does not show it performing very well.

JavaScript would not be my first choice language for a layout evolver... :-)

Cheers, Ian

It's looks really lopsided to the left hand (and the KLA confirms my suspicion). What is the deal with the top row? He says he wants to reduce pinky usage, but his layout has 'DAU' all on the left pinky.

JavaScript could be interesting if it was a webpage that has UI to allow users to fidget with the parameters. Nothing to download or install. Alas that doesn't seem to be the case. (Although after seeing his layout, I wouldn't trust it anyway.)

I agree I (we) should provide easy ways for users to install BEAKL.

I use and prefer autohotkey. This script converts Dvorak into BEAKL EZ: ez.ahk

note some keys have been remapped on my Kinesis keyboard. like ` and \ to the outside pinky. numlock to the left of number row.

MSKLC is probably the better solution long term. but I don't have experience with it.
