DOTKey is an exciting and new way to type. Unlike traditional keyboards with their “one size fits… nobody” approach, We designed DOTKey to offer a unified and efficient user interface regardless of hand size, number, handedness etc. Our patent-pending approach enables a typing method that is:

Fast: Up to 65 words per minute or more!

Comfortable: Automatically calibrates to your hand-size and orientation!

Ambidextrous: DOTKey is for everyone!
