Calculates the number of finger movements required to type something using different keyboard layouts.

keyboard-layout-analyzer

Calculates the number of finger movements required to type something using different keyboard layouts.

I was obsessed with different keyboard layouts. Like everyone else, I wanted to find the ULTIMATE keyboard layout. Well, It's not that easy, so I wrote an application which takes multiple lines of characters and calculate the finger movements to that is required to type it.

Supported keyboard layouts are

• qwerty
• dvorak
• halmak
• workman
• colemak

How to Interpret

• Finger Movements (Lower the better) - User has to move the finger to press the key.
• Same Finger Usage (Lower the better) - Same finger usage to type different letters ("lo" in "hello" with QWERTY).
• No Movement (Higher the better) - Move finger movement needed to type these letters because the finger should be on the letter when touch typing

Sample Output 1

Command: echo hello | keyboard-layout-analyzer

Following are the results for for typing "hello".
