1. QWERTY keyboard 

QWERTY keyboard, the layout is based on a typewriter. The layout was discovered by Scholes, Glidden and Soule in 1878, and later became a standard commercial typewriter in 1905. QWERTY keyboard was designed in such a way that is most often pressed key is located as far apart as possible, so that it can minimize the congestion at the time of typing (on a mechanical typewriter). Although the QWERTY layout is widely used, but it has some weaknesses and inefficiencies. For example, 48 percent of the movement between successive letters have to be done with a hand. Only 32 percent of beats performed on the home row (row beginning from the position of fingers on the keyboard). Load is greater than the left hand right hand (56 percent). The most obvious example of the inefficiency of the QWERTY layout is typing the letter 'a' which is quite often used, but must be done by the little finger is the weakest. 

2. Projection Keyboard  

Keyboard projection was developed to save space as a conventional keyboard is still considered to be space-consuming work.
This keyboard uses motion sensors to detect movement of your fingers. To use it, you just find enough flat space to yield a maximum projection. 

3. Dvorak Keyboard  

Dvorak Keyboard (1932), where the arrangement of letters are arranged such that the right-hand man burdened with more work than with your left hand. In addition, the Dvorak layout was designed so that 70 percent of the beats fall on the home row, so that it can reduce fatigue due to typing (more ergonomic). Numerous experiments showed that the more efficient Dvorak layout 10-15 percent compared with a QWERTY layout. 

4. Keyboard KLOCKENBERG  

The keyboard was made with the intention of perfecting the existing types of keyboards, that is by separating the two halves of the keyboard (the left and right). The left and right of the keyboard are separated by 15-degree angle and sloped downward. In addition, the keyboard has buttons KLOCKENBERG made closer (thin) with a desk, so feel more comfortable. Keyboard KLOCKENBERG looked funny because it separated the left and right are relatively more space-consuming. 

5. Keyboard Maltron  

Unlike a flat keyboard in general, this keyboard is made slightly concave inward. Considering that when the fingers are positioned to be typed, then the radius is guaranteed not to form a straight line. Maltron manufacturer believes that basically, only used 8 fingers of ten fingers available when people type on a keyboard typing on the keyboard biasa.Dengan usual, then the finger must adapt to the shape of the keyboard. It is claimed by them can cause RSI (Repetitive Stress Injuries). Meanwhile, using Maltron, keyboardnyalah which will adjust by hand. With its unique shape like this, Maltron ensure the comfort of your fingers when typing so it does not cause RSI can even improve your typing speed will be used for the 10 fingers instead of eight fingers. 

6. Keyboard CHORD  

Has only a few buttons between 4 to 5. To enter a letter have to press multiple buttons simultaneously. Compact size, ideal for portable applications. Short training time, reflecting the emphasis Tombo-letter form the desired high speed Less popular, due to the use of time will cause fatigue in the hand. 

7. Keyboard Alphabetik  

The buttons on the keyboard alphabetik arranged exactly as on the QWERTY or Dvorak layout, but the arrangement of letters as in the sequential order of the alphabet. Alphabetik keyboard also can not rival the popularity of QWERTY layout, but usually mostly found in children's toys, so children are taught to know the alphabet letters. For users who are not typists, maybe the layout is quite helpful. However, the results of testing, the use of layout like this would slow down typing speed. 

8. Numeric Keyboard  

To enter a number in large numbers, people prefer to use the numeric keypad (numeric keypad) the layout of the buttons can be reached by hand. 

9. Kitty Kitty is a kind of keyboard that serves to enter data into PDAs, Pocket PCs, and Warable. The keyboard of this type was developed by the University of California at Irvine.
