A Journey of keyboard layouts: Alphabetic, QWERTY, DVORAK keyboardNo Comments
The alphabetic as we have studied in our kindergarten a to z is not the best keyboard layout design because it does not take into account these factors which are essential for key layout on a computer are
- 70-80% of the keystrokes you will make should be from the home row.
- It should not cause very jerky movements of hands giving fatigue or RSI (repetitive strain injury) for fingers.
- Both the hands should be used alternatively to increase the typing speed.
Clearly alphabetic keyboard never satisfied these conditions and hence it was discarded.The next came qwerty.
QWERTY – Stands for nothing but qwerty it is the first five letters of our standard keyboard layout.
The first point I would like to mention is that in qwerty the arrangement of keys is not optimal for typing but for backward compatibility reasons (with the old mechanical typewriters ,they needed a slow typing keyboard for not jamming the arms which hit the paper …bullshit we suffer ) this layout of keys have been ported to computers too. So if you want to type faster you can easily stop using qwerty and adopt the Dvorak input keyboard design.
The Dvorak keyboard design is based on research done by Dr. Dvorak and is designed on typist’s comfort in mind.This is most easy to learn, it is best suited for right handed it has most used constant on right side of home row and all vowels on left side of the home row.A separate series is available for single handed individuals.
