About

Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs.

It features a 3x3 grid layout, as many older phones had, and uses swipes for the less common letters. Initial testing shows that you can reach ~25 words per minute after a day of use.

Instead of relying on profit-driven, privacy-offending word and sentence prediction for accuracy, as do most popular phone keyboards like Gboard and Swiftkey, Thumb-Key uses large keys with predictable positions, to prevent your eyes from hunting and pecking for letters.

As the key positions get ingrained into your muscle memory, eventually you'll be able to appromixate the fast speeds of touch-typing, your eyes never having to leave the text edit area.

This project is a follow-up to the now unmaintained (and closed-source) MessageEase Keyboard, which is its main inspiration.

On desktop, I use the AI-designed Halmak Keyboard, and its had great results.

Rather than manually picking letter positions, Halmak was designed by an evolutionary algorithm, based on a given set of criteria, and sample text.

I designed the original english thumb-key layout manually, with trial-and-error, and based essentially on 3 criteria:

Letter frequency
Alternating thumbs
Thumbs come from the bottom corners, so lower and edge tiles are easier than higher.

But I did not take into account things like digrams / trigrams, and I don't know enough about evolutionary algorithms to do it.

Would anyone be interested in tackling this problem?

We could definitely still use some help. Check the github issue, but dev has stalled on it.
