Abstract
Apparatuses for a distal chording keyboard are described. Key configurations are selected based on the frequency of use of the characters. In one embodiment, a chording keyboard comprises two keypads, one for use with each of a user's hands, the keypads disposed on a distal side. In one embodiment, one of a user's hands provides alphanumeric input on one keypad, and the other hand provides cursor and special function control on another keypad.
