SWORD utility

SWORD is command line utility that sorts words by typing effort and calculates keyboard layout properties using frequency dictionary.

SWORD layouts

SWORD based optimizer can be used for layout optimization.

SWORD layouts listed below are ortholinear SWORD optimizations with thumb keys. Some of those layouts are adaptive, some are static.

Tandem layouts

Tandem layouts are ortholinear SWORD optimizations with adaptive tandem keys.

Rain layout

Aries layout

Unicorn layout

Snow layout

Norto layouts

Norto layouts are Scandinavian ortholinear SWORD optimizations.

Norwegian layout

Danish layout

Swedish layout

English layout

Orþorn layouts

Orþorn layouts are SWORD optimized ortholinear layouts with Þ key.

Þunder layout

Tensor layout

Orthostat layout

Orthostat layout is simple static ortholinear SWORD optimizations.

U-turn layout

U-turn layout is experimental offgrid SWORD optimization.

Saint layout

Saint layout is ortholinear SWORD optimization with configurable load distribution.

Kvant layout

Kvant layout is Ukrainian ortholinear SWORD optimization.

Typing effort

Optimized layouts have rather low typing effort, both on Carpalx and SWORD scale.

More detailed reports are listed in table below

Layout		Typing effort

Tandem	Rain	1.269	1.365
	Aries	1.253	1.360
	Unicorn	1.255	1.313
	Snow	1.321	1.375
Norto	Norwegian	1.298	1.381

U-turn		1.380	1.377
Saint		1.310	1.382
Kvant		1.617	1.523

Balanced word lists

There are balanced word lists with reasonable load distribution and typing effort characteristics.

Those lists are layout specific and can be incorporated in typing lessons.

One can use SWORD type utility for training.
