KeyboardBattle

KeyboardBattle is a simple program that compares the performance of keyboard layouts according to two metrics, reach effort (travel from the home row being increasingly effortful) and alternation effort (typing consecutive keys with a single hand being more effortful). For both, a lower value means less effort.

The program comes with the QWERTY, Dvorak, and Colemak layouts. The format for a keyboard layout description file can be discerned from lib/keyboard_battle/keyboards.rb.

Installation

$ gem install keyboard_battle

Usage

E.g., keyboard_battle my_text.txt, or try keyboard_battle --bundled to use some texts from The Internet Archive.

Limitations and shortcomings

Only ASCII characters will be counted (though any character may appear in the source text).

Bundled texts

Except for "the quick brown fox," bundled texts are sourced from archive.org.
