The origin of the keyboard starts, unsurprisingly
with the first typewriters.
There were a variety of type-writer-like devices around going back the 18th century, before
one Christopher Latham Sholes, with some help from a few other guys, came up with one that
would become the first commercially successful typewriter in the 1870s.
Much like many typewriters since, Shole’s device used letters and characters on the
ends of rods which were called typebars.
When a key was struck, the typebar would swing up and hit the ink-coated tape which would
transfer the image onto paper.
The difference between this and more modern incarnations, however, is this first device
more or less mimicked the layout of a piano keyboard and positioned the keys in alphabetical
order in those two rows.
This arrangement had a number of problems, but most notably as people got faster at typing,
it caused the typebars of the most commonly used combination letters of the alphabet to
be positioned close together, so when the keys were hit one right after the other at
any fast speed, the keys would jam.
To solve this, the keys were rearranged to put commonly used consecutive letters further
away from each other to reduce jams.
While you might be thinking, and it is widely claimed, this was to fix the problem via making
people type slower, all evidence point to this simply being to position the arms of
these letters better so they’d be less likely to cross.
It should be noted here that you’ll often read now-a-days that this whole jamming story
is a myth, and that Sholes was simply trying to cater to telegraph operator’s usage in
making the change.
Everyone claiming this, including the Smithsonian Magazine, which normally does a lot better
research, cites one 2011 paper, On the Prehistory of QWERTY, by Koichi Yasuoka and Motoko Yasuoka
of Kyoto University as their source.
However, what the people parroting this fail to mention is that, if you go actually read
the paper as we’re wont to do when researching, this paper is just speculation with no real
direct evidence to back their claims up.
The authors of the paper further incorrectly state that the idea that it was a typebar
jamming as motivation didn’t pop up until the 1980s.
In truth, the idea that the change was spurred by the typebar jamming came about in 1923
in the book The History of the Typewriter, developed by authors from the Herkimer Historical
Society,
So what was their source for this claim?
None other than Sholes notes and many correspondence concerning the development of the typewriter.
Now, normally we’d then go and actually read through said notes and letters to find
where Sholes actually says this to verify for ourselves, but in this case, while the
letters and notes still exist, they only seem to exist in the state archives of Madison,
WI and unfortunately we don’t exactly have the budget to send someone out there to verify…
So that’s where we had to stop on this particular rabbit hole.
If anyone from Madison Wisconsin wants to go do a little digging further for us, we’d
be much obliged.
In the meantime, given the authors here aren’t likely to have made this jamming story up
out of thin air and were using Shoels’ notes and letters as the base of their work, it
seems probable that jamming really was the motivation for the change.
Whether you’re on board with us on that one or not, one thing the aforementioned 2011
paper did get right was, once it was clear a change was needed to stop the jamming, Sholes
really did work with telegraphists on the final layout to try to cater to their needs
as best he could.
But this shouldn’t be much of a surprise given these were among his first customers.
In fact, his literal first sale of the 1868 model was to Porter’s Telgraph College in
Chicago.
In any event, in 1868, in collaboration with several other people, Sholes settled on an
arrangement of the letters on the keyboard for better spacing between popular keys used
in combination.
The results was that this initially made it difficult for people to find the letters they
needed to type efficiently, unlike when the letters were in alphabetical order.
However, thanks to less likelihood of jamming, once one became proficient in the new layout,
it was found to be a faster typing experience.
Of course, at this point in history, people were still predominantly using the hunt and
peck method, rather than 10 finger typing, so nobody was blazing fast or anything.
As for this keyboard though, it was the beginning of some semblance of the QWERTY we know and
love today, which first appeared in 1872, though it wasn’t quite exactly the one we
have yet.
For that, we have to fast-forward ever so slightly.
The first more widely available typewriter machine found its way on the market in 1874
through Remington & Sons.
The device was called the Remington No. 1, or sometimes the “Sholes and Glidden”
typewriter, with Remington and Sons acquiring the rights to it and its near QWERTY keyboard.
This, however, did not sell well.
Four years later, however, after slight modifications to the arrangement of the keyboard were made,
we finally have the qwerty layout in the famed Remington & Sons Remington No. 2 model, which
also notably included the ability to type both capital and lowercase letters by using
the shift key.
And if you’ve ever wondered why the Shift key is called that- well, wonder no more-
The shift key received its name because it caused the carriage to shift position in order
to type either a lowercase or capital letter which were on the same typebar.
Although the shift key we use on our keyboards today does not cause the machine to shift
mechanically, the name stuck.
In any event, as the typewriter rose in popularity, people stopped complaining about the weird
arrangement of keys and started memorizing the keyboard and learning how to type efficiently.
What particularly helped the sales of the Remington No. 2.
Model was that Remington offered classes for a very small fee to learn to type proficiently
with the keyboard.
They also offered certification in the keyboard, which was a good thing to have for a typist
looking for a job, and further good for companies wanting to ensure they could get someone proficient
right away just by their resume.
Within a little over a decade there were over 100,000 typewriters using this qwerty layout.
As it came to dominate, although other alternate keyboards tried to break into the market,
most people decided to stay with the QWERTY layout largely due to the widespread popularity
of the typewriters that used it.
The nail in the coffin to other layouts occurred in 1893 when Remington and four other major
typewriter makers all merged and set the QWERTY as the industry standard.
There is one other layout, however, that over the decades has had a small amount of traction
and induced many a flame-war on the interwebs, often touted as superior to the qwerty for
many reason- the Dvorak layout.
This has its origins in the 1930s when Professor August Dvorak of Washington State University
set out to develop a more user-friendly keyboard.
He ultimately changed the layout such that all of the vowels and the five most commonly
used consonants were arranged on the home row (AOEUIDHTNS).
The general idea of this keyboard was to try to minimize the need to move your fingers
anything but pressing on a key with the most commonly used words.
For example, with the Dvorak keyboard, a person could type approximately 400 of the English
language’s most common words just by using the keys of the home row, compared to in the
ballpark of 100 of those most common words on the QWERTY keyboard.
It is also optimized such that you’ll more frequently alternate hands pressing the keys
to further increase speed.
So does this actually speed up typing?
Not in any real world noticeable way.
It turns out in the countless studies done on this, the general consensus seems to be
that the average increase in words per minute is typically only about 2% to up to 10% or
so, give or take depending on what study you want to go with.
So, for example, if you used to type at 60 words per minute, you might expect something
like at most 66 words per minute or so once you take the necessary time to become proficient
at the new arrangement.
That said, some people see much higher improvement rates, even sometimes on the order of 30%-100%
boost in words per minute rates.
However, if you look closer, people that see these types of huge improvements tend to be
people that learned to type on qwerty keyboards without any formal training and generally
had suboptimal speeds there because of it.
Thus, if they trained properly on the qwerty keyboard, they’d also have seen a large
increase in words per minute.
As you might imagine from this, actually testing which is superior, if either, has been a bit
difficult, given there’s potential for a lot of noise in the data with so many people
at so many varied levels of proficiency on the QWERTY before being formally trained on
the Dvorak.
Thus, in an effort to get around this problem, there have been studies that have taken the
humans out of the experiment.
Exhibit A: a January of 2006 paper titled The Great Keyboard Debate: QWERTY vs Dvorak,
by Kathryn Hempstalk of the University of Waikato.
In this study, she measured things like the average travel time it took for fingers to
move up and down rows and press and the like for giving strokes on the keyboard.
She then took 21 lengthy books, including Moby Dick, and simply added up the time it
would take to type those texts out using the Dvorak and the qwerty layouts, given the known
average movement times for proficient typers- an ingeniously simple and accurate way to
take the human element out.
So what were the results?
Timing-wise, even with such a large sample size, neither keyboard was really faster than
the other in the general case.
She summed up the study by stating, “the Dvorak layout is the most efficient because
it requires the least amount of effort to type some given text, even though it [takes]
approximately the same amount of time as the QWERTY layout.”
At this point you aficionados might be already heading to the comments to tell us that Dvorak’s
initial studies, particularly one conducted with the U.S. Navy in 1944, looking at his
keyboard’s superiority showed far more glowing results in increased in speeds- a whopping
74% increase and reduction of typos by 68% once the keyboardists were trained up.
The problem was that follow up studies, such as one by the U.S. General Services Administration
in 1953, among others around this time, couldn’t replicate these results, though some speculate
these studies were rigged against the DVORAK.
Whether that’s true or not, a surprising number of studies since, as noted, haven’t
been able to replicate the original results either except in cases where someone hadn’t
bothered to be properly trained in the QWERTY layout in the first place.
Whatever you want to believe on whether the 1950s studies were rigged or not, these studies
ultimately killed the Dvorak keyboard’s momentum as the majority of people and companies
didn’t want to commit the time or resources it would take to train on a new keyboard if
the improvement was only marginal at best.
And since then, not much has changed on that front.
That said, proponents of the Dvorak keyboard who accept that the Dvorak isn’t actually
noticeably faster, do point out there are other benefits to the Dvorak beyond speed,
primarily in less wrist and finger fatigue and supposedly fewer typos (though the data
on this latter one is mixed despite widespread claims).
While less finger and wrist fatigue does indeed appear to be a genuine benefit, proponents
of just sticking with the QWERTY tend to be quick to point out that it takes a rather
long time to master a new keyboard layout, with people who’ve made the switch to Dvorak
generally claiming it took them about 1-6 months to reach the proficiency they have
on the qwerty.
And further, it takes an awful lot of continual typing before most find themselves fatigued
on the qwerty layout anyway.
Thus, for the majority of people, it’s probably not worth the effort of re-training.
Further, QWERTY disciples point out that losing proficiency in the qwerty layout that’s
pretty much everywhere, is potentially an issue of making the switch.
Though to that, many people we read who did become proficient on the Dvorak noted that
for them, their brains had no issue switching back and forth between layouts so long as
they continued to regularly use both.
The human brain is pretty amazing, it turns out.
Perhaps the bigger issue for these individuals was that a lot of short cut key strokes in
various software are geared towards the qwerty layout, and can often be quite awkward on
a Dvorak keyboard, though there are ways around this if one wants in some cases with some
autohotkey scripts that convert for you.
A similar issue is often pointed out by computer programmers in that the symbol placement on
the Dvorak is extremely sub-optimal when programing in C and its many off-shoots.
Proponents of the Dvorak, however, correctly point out that all these problems are only
problems because almost everyone uses the qwerty.
If everyone switched, you’d get a very tiny boost in speed, slightly less finger and wrist
fatigue, and these other problems would go away.
But of course, as it’s only a slight improvement, and not a game changing one, the QWERTY keyboard,
much like the useless letters Q, X, and C, persevere through today and seemingly will
continue to do so for the foreseeable future, though there are some new efforts being made
for better keyboard layouts when typing with just two thumbs as people do a huge percentage
of the time now.
But even then, the qwerty still dominates to date.
As Dr. Dvorak himself aptly summed up- “Changing the keyboard format is like proposing to reverse
the Ten Commandments and the Golden Rule, discard every moral principle, and ridicule
motherhood.”
