imo, the [1]datahand keyboard makes a lot more sense than chorded keyboards. Each finger has access to four characters mapped to up, down, left or right. All it takes is a short movement of the finger to press a key.
Hm, you might be right. But as how I understood it, the datahand is trying to let you use the same movements as you are already using on a normal keyboard, only without having to travel the full distance. I have a hard time seeing why that shouldn't work
Pushing down and aligning your fingers is incredibly accurate but rolling/moving your fingers is not.
