A brief history of keyboards
Sylvain Fankhauser, Liip
June 2013
If bikes evolved the same way keyboards did, here's
how you'd be doing Bike to Work…
In the 1870s, Christopher Latham Sholes created the
first typewriter
Its first layout looked like this…
3 5 7 9 N O P Q R S T U V W X Y Z
2 4 6 8 . A B C D E F G H I J K L M
It worked, but typewriters had a big flaw…
Jamming
The qwerty layout was created to prevent jams by
increasing the distance between frequent letters
In the 1930s, August Dvorak analyzed this layout
WTF?
August Dvorak
He came to the conclusion that qwerty is highly
inefficient
> 7%
5 – 7%
2 – 5%
< 2%
32%
52%
16%
So he created the Dvorak layout, aka Dvorak
Simplified Keyboard (DSK)
> 7%
5 – 7%
2 – 5%
< 2%
70%
22%
8%
This layout focuses on usage of the home row,
hands alternance, and n-grams (mostly bigrams)
The Dvorak layout does not require any special
keyboard
Today we're using a keyboard layout that was
designed for mechanical limitations that don't
exist anymore
Even on non-mechanical devices
Keyboards are like 1870s bicycles not only
because of their layout
Right hand
Right handLeft hand
WTF?
Today's keyboards are designed to overcome
limitations of 1870s typewriters
Ergonomic solutions exist
They're still expensive and not easy to find
“I'm tired of trying to do something worthwhile
for the human race, they simply don't want to
change”
August Dvorak
Thank you
