keyboard_history : History of computer keyboard

The first six letters at the top left of your keyboard spell it out QWERTY. This arrangement of letters, along with the other 20 on the traditional keyboard were actually arranged that way to make the job of typing more difficult.

The first commercially successful typewriter was developed by Christopher Latham Sholes in 1873. Originally, the keys were arranged alphabetically. However, a problem soon arose. People became so adept at using the keyboard that the keys would stick or jam when struck in quick succession. In order to overcome this problem Sholes decided to make the job of typing as slow as he possibly could. His solution? He placed the most frequently used keys as far apart from each other as he could. His keyboard became known as the QWERTY keyboard.

So, that is the reason why your keyboard is formatted the way it is. Ironic, considering that every other aspect of your computer is streamlined for maximum efficiency and yet you have to labor over a 127 year old system designed specifically for inefficiency. And inefficient it certainly is. For one thing, QWERTY was not designed for touch typing, which came much later. For keys that are not in the middle or home row it is necessary to reach across diagonally. This is difficult and leads to a high error rate.

Some claim that there is a better system called the DVORAK keyboard format. It was designed by August Dvorak in the 1930s. Dvorak's keyboard put nine of the most used letters in the middle row of the keyboard. This allows the typist to write over 3,000 words without the fingers reaching. In comparison, only about 50 words can be typed on a keyboard without reaching on QWERTY's middle or home row. Another advantage of the DVORAK keyboard is that the workload is much reduced.

Does the DVORAK system really improve performance? In order to prove that it does August Dvorak retrained 14 Navy typists during World War Two. The result? After just one month their work productivity rate improved by an amazing 74 percent. Accuracy improved by 68 percent. So, you would think that people would be jumping over each other to switch over from QWERTY to DVORAK. Surprisingly, this has not proved to be the case. DVORAK keyboards are readily available for most computers and on typewriters, yet by and large they remain unaccepted.

Another supposedly better keyboard than the DVORAK version is the MALT keyboard devised by Lillian Malt. The Malt keyboard does away with staggered rows, gives greater use of the thumb and makes it easier to reach the backspace and other normally out of the way keys. Unlike the DVORAK keyboard, however, the MALT version will require special hardware I order to be installed onto your computer. Modern designs are also available on both the DVORAK and the MALT keyboards that are specially contoured to alleviate the physical problems associated with the traditional typewriter style keyboard. DVORAK have also put out one handed keyboards which give a free hand for other tasks while typing.

Typing posture, ergonomics, prevention, treatment The most important element of both prevention and recovery is to reduce tension in the muscles and tendons. This requires learning how to relax. If you're under a load of stress, this is doubly important. Tune out the world and breath deep and regular. Relaxing should become a guiding principle in your work: every three minutes take a three second break.

• Let your shoulders relax.
• Let your elbows swing free.
• Keep your wrists straight.
• Pull your chin in to look down - don't flop your head forward.
• Keep the hollow in the base of your spine.
• Try leaning back in the chair.
• Don't slouch or slump forward.
• Alter your posture from time to time.
• Every 20 minutes, get up and bend your spine backward.

For some people, wrist supports seem to work wonders. If you drop your arms at your side and then lift your hands up at the elbow, you want your keyboard under your hands when your elbows are at about 90 degrees.

First, and foremost of importance: if you experience pain at all, then you absolutely need to go see a doctor. As soon as you possibly can. The difference of a day or two can mean the difference between a short recovery and a long, drawn-out ordeal. GO SEE A DOCTOR. Now, your garden-variety doctor may not necessarily be familiar with this sort of injury. Generally, any hospital with an occupational therapy clinic will offer specialists in these kinds of problems.
