Apparatus for ergonomic typing

An apparatus for ergonomic touch typing, the apparatus comprising:

• a first surface having first set of keys including a plurality of alphabetic keys, the first set of keys being operable by a user's thumbs;
• and
• a second surface opposite the first surface and having a second set of keys including a plurality of alphabetic keys, the second set of keys being operable by the user's fingers which are digits two through five of the user's left and right hands, the second surface including first structures recessed in the second surface which are home positioning channels for home positioning of fingers of the user's left and right hands on home position keys and at least one second structure for positioning of the fingers of the user's left and right hands when moving to and from the home positioning channels during typing, wherein the first structures include digits three through five home positioning channels that each surround a plurality of the home position keys and index finger home positioning channels, wherein the digits three through five home position channels and the index finger home position channels separate the second digit from digits three through five when the user's fingers are in the home positioning channels, wherein the at least one second structure comprises a wall that extends outward from the second surface and laterally across the second surface separating a region of the second surface that includes keys proximal to the index finger home positioning channels from a region of the second surface that includes keys proximal to the digits three through five home positioning channels, wherein the index finger home positioning channels include cylindrical depressions in the second surface, and wherein the digits three through five home positioning channels include elongate depressions in the second surface.
