A Brief History of Keyboards
1.
A brief history
of keyboards Sylvain Fankhauser, Liip June 2013
2.
If bikes evolved
the same way keyboards did, here's how you'd be doing Bike to Work…
3.
4.
In the 1870s,
Christopher Latham Sholes created the first typewriter
5.
6.
Its first layout
looked like this…
7.
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
8.
It worked, but
typewriters had a big flaw…
9.
Jamming
10.
The qwerty layout
was created to prevent jams by increasing the distance between frequent letters
11.
In the 1930s,
August Dvorak analyzed this layout
12.
WTF? August Dvorak
13.
He came to
the conclusion that qwerty is highly inefficient
14.
> 7% 5 –
7% 2 – 5% < 2% 32% 52% 16%
15.
So he created
the Dvorak layout, aka Dvorak Simplified Keyboard (DSK)
16.
> 7% 5 –
7% 2 – 5% < 2% 70% 22% 8%
17.
This layout focuses
on usage of the home row, hands alternance, and n-grams (mostly bigrams)
18.
The Dvorak layout
does not require any special keyboard
19.
Today we're using
a keyboard layout that was designed for mechanical limitations that don't exist anymore
20.
Even on non-mechanical
devices
21.
Keyboards are like
1870s bicycles not only because of their layout
22.
Right hand
23.
Right handLeft hand
24.
WTF?
25.
Today's keyboards are
designed to overcome limitations of 1870s typewriters
26.
Ergonomic solutions exist
27.
28.
They're still expensive
and not easy to find
29.
“I'm tired of
trying to do something worthwhile for the human race, they simply don't want to change” August Dvorak
30.
