pinkyache said:I like the look of Imak, it looks familiar for some reason. What's the rational with the <, >. positions?
The reasons are:
1- during the last 5 months I was analyzing text from famous books (http://www.gutenberg.org/browse/scores/top) using this tool http://www.codesharp.co.uk/dvorak/ and in every case the probability of having "e," is much higher than having any other key combined with "," and of course the probability of having "e." turned out to be much much less. So by placing "." under "e" this would decrease the same finger ratio.
2- increasing alternation because each time you type "." , "," or ";" you have to follow it by hitting the spacebar with the same right hand. This of course applies for right handed users, who are the majority by far.
3- On QWERTY and due to the fact that the left hand is slightly below the right hand, since usually we hit the spacebar with the right, it turned out after testing that if I replaced 'V' with a key of the weight of 'F' ,for example, the left index start to suffer from the downward pull, and it took me weeks to recover from this tension. So I am limited with the keys that I can replace V and B with. However on the right hand there is no problem and no body have experienced problem with going to N or M
4- I was testing a mirrored version of Imak which I will show below, and I was really convinced that the 'L' and the 'D' positions should be swapped since first the "E" key is faster than the "G", which requires some stretching of the index finer (Referring to QWERTY for E and G). I have proved this, at lest, for me by typing simple compos
"ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed ed"
"fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg fg"
Also "L" is compined with a lot of words and it that position it decrease the jumping ration between 2 rows a lot, so make Imak like this has help me to put 'L' in the optimal position.
5- the last reason is that ',' is more common than '.' and the C position is faster than X on QWERTY, and i feel it requires slightly less wrist flex
Below is the Id of the mirrod Imak that I was testing and I reached a speed higher than dvorak for almost the same amount of training while trying to maintain dvorak, but actully to advance I had to stop dvoraking for three days and then after that it took me a day and a half to go back to my original speed on dvorak. Now I sopped the mirrored Imak and I dvanced on Dvorak to a max of 70 WPM on typeracer and 63 WPM for 5 minutes on high games, which actually took me less time than colemak and less training and I still mix some Imak with dvorak which slows me down.

this mirrored version of Imak that I was testing has all the time lower finger ratio than Colemak, lower multiple row jumps but slightly less alternation than the final version of Imak.
Note: Non of the layouts that I have designed have caused me wrist pain, which seems to prove my theory, but there is something else which I will discuss later (maybe tomorrow).
erw said:@Nimbo: Do you have anything to back up that it has more/better rolls than colemak? (and "6- combines alternation and rolling..." seems a bit weird. Is there any layout where that doesn't apply?)
first we must agree on what a roll is: According to my definition of a roll, it is a sequence of three letters typed with the same hand either in inward or outward manner but not both. So a bigram "ou" is not a roll for me :) and taking this definition into account if I compared Imak to Colemak I do not see much rolls on Colemak. On the right hand side of Colemak I see "ion" and "oin" . "oin" is a roll, but it is not that common. On the other hand, I do not consider "ion" and "you" as a roll, and I actually consider them to be a devastating compos on the right hand. For, example type " ion ion ion ion ion ion ion ion ion ion ion ion ion"
then revers i with o, and type
"oin oin oin oin oin oin oin oin oin oin oin..."
and see how oin feels much better.
The point is that while an outward roll could be easy on most of the fingers, it is actually feels really bad on the pinky especially if it is combined with an inward roll like the case of "ion". During the last month of training on Colemak, I had to stop typing some days because of pain in the bone of my small right hand pink, and the damage was not only happening to my hand but also to my keyboard (maybe later I post an image of the wear). Now if we go to the right hand, I can see ars and rst on colemak, and the only words I typed containing ars were years and hears, that is not to say there are not may words that contain this roll, but unfortunately I have not met them.
So, according to my definition, I find no rolls at all on dvorak and QWERTY, correct me if I am wrong :). Anyway, Imak is still in the testing procedure, and it would be nice if all of us cooperate to produce a nice comfortable alternating layout similar to dvorak, but balanced has low finger ration, and eliminate the problem of 'SL', which I do not find much problem BTW.
