Did you know The reason Position Letter on the Keyboard?

  • i
  Have you ever wondered, why the arrangement of letters in a typewriter keyboard, computer, PDA until we form "QWERTYUIOP" and so on? Why not be just a sequence such as "ABCDEFGH" and so on? Maybe some of you already know the story, but if you do not know can read here. If before I make a post "computer history", this time we will bring about the history of the keyboards that we often use in operating a computer.

Well not to reproduce intermezo stout, we direct it to follow the story.
That said, the keyboard has been created since the year 1860an by Sholes (top left) and Dunsmore (bottom left). Originally they were made ​​sequentially in alphabetical order. However, gradually with increasing capabilities (custom) user, typing speed becomes faster when the mechanism of the engine while it is still simple. Consequently, (line) of certain key to frequent traffic jams and hinder the work.

       Based on their experience, eventually drafted a keyboard that was made deliberately complicated and inefficient for JAMMED keyboard is not easy. Typewriter design was later sold to Remington to be mass produced in 1873. Structure is divided into four rows, the top line of "23456789 -" second line "QWE.TYIUOP", third line "XDFGHJKLM", and the bottom line "AX & CVBN?; R".

    Over time, technology is advancing rapidly and the problem of the keyboard keys are often jammed been overcome with better mechanical design. A number of alternative keyboard designs also come on the market. One that is quite popular is the Dvorak Simplified Keyboard (DSK) made by August Dvorak in 1936. The design is claimed is a design more efficient, faster, and egronomis.

QWERTY actually have many drawbacks such as making your left hand overload, especially when writing in English (same thing I felt when writing in Indonesian language). QWERTY also make your pinkie overload. Research shows that the uneven distribution of the letter so that your fingers have to cross over from line to line - when calculated finger typists will typically run more than 20 miles per day compared with the DSK is only 1 mile.
Unfortunately, people still refuse to turn away from the design of "QWERTY" although the design is not the best design. Although technology can solve the key problem of jamming, people stick with the design of "QWERTY" design rather than other, more superior. Instead, the QWERTY instead crowned the international standard in 1966.
The same thing also occurs in Microsoft Windows. We certainly know that Windows is not the best operating system, whether it be in terms of security, convenience, performance, until the matter of beauty. However, because the market penetration of Windows already so heavy, people got used to using Windows and operating systems become standardized.
Is not nothing better than Windows? Of course not. But people need to think about it a few times before turning away from these standards. They have to face barriers such as cost factors, compatibility issues, the learning process, the time factor, and much more. As a result the number of those who are faithful much larger than an apostate. This is what makes Windows or QWERTY became the standard - even though they are not the best.
In the scientific world, this phenomenon is described as the concept of path dependency and network externalities. In essence, innovation does not produce outcomes that out of the blue, but it is a development that could be predicted from a has-been. In addition, the value of innovation will be higher when it is used by more people. At a certain stage, the innovation will become the standard used by the public.
