Abstract
Keyboard for one-handed touch typing derived from a normal Sholes keyboard, where each character-key is assigned two characters (for instance T/Y), thereby reducing the number of keys to approximately half the number of keys on a normal Sholes keyboard. The choice between the two alternative characters of a specific key is based on the mode of depression of that particular key, and hence no separate key for choise between the two alternatives is needed. The characteristics of the keyboard can either be set once and for all or can be particularly adapted to the specific user of the keyboard, such as for instance to the user's writing speed.
