Maltron vs Dvorak keyboard Layout
Is the Maltron layout more efficient than Dvorak?
There's the Maltron layout. I always questioned its claim that it is a improvement over Dvorak .
Here is the Maltron layout.
Note that Maltron has this odd e key placement, for the left thumb. That always throws me off, regarding it alien.
Now, look at the letter frequency in English.
You see that the letter E is significantly more frequent than the second most frequent letter T.
So, the Maltron put it on the thumb. But how much better is thumb than index finger or pointing finger?
We can explore this question by looking at another key we use for thumb, the space key. We use thumb for space. How frequent is space?
A quick calculation shows, the space is almost twice frequent as E!
So, this means, E for thumb is a major improvement. We type space with thumb all day, and it didn't have a problem. There is nothing wrong with the oddity of placing a letter for the thumb.
So, this means, the Maltron layout is significantly better, simply because it added a home key (the thumb key), and moved a significant load to the strongest finger. But keyboard layout optimization is more than just choosing letters for home keys. There are many other considerations that CANNOT BE IGNORED, such as finger travel distance, same finger movement, bigram, …. However, mapping most frequent letters to the home keys is the most important criterion, and the specific move of E to thumb is a huge improvement in this aspect. So, even if Maltron layout screwed up in other aspects, it is probably still a better layout than all the others that do not consider thumb key, such as

So, you keyboard layout fanatics out there, this means, quickly, run and buy a Maltron or Kinesis keyboard, remap your keys, for the sake of perfection, start learning to type all over!
If you are actually interested in doing this, you need a keyboard with at least 2 thumb keys.
