I’m in the market for a keyboard with a well/concave shape. Preferably split. I’m looking for a built board, not a kit. I’m aware of the Dacty, Glove80 and Kenisis. Am I missing any? Thanks!
If you’re interested in something different, one really promising keyboard project just launched: Svalboard.
I have no experience with the Datahand, but the lateral finger movements necessary on that board look 😱. On a regular column stagger keyboard only the index finger makes a lot of lateral movements (meh) and the thumb (but following the natural thumb arc anyway).
