1. An alphanumeric keyboard having a pre-defined key arrangement, wherein the pre-defined key arrangement includes:
- at least one QWERTY typing section comprising;
a plurality of central keys;
a plurality of intermediate keys disposed outboard of the plurality of central keys;
one or more peripheral keys disposed outboard of the plurality of intermediate keys;
wherein the central, intermediate, and peripheral keys are arranged into rows;
wherein the plurality of central keys of each row are configured such that each central key is provided at a same gable angle and disposed along a substantially straight reference line inclined at said same gable angle with respect to a plane of the keyboard; and
the one or more peripheral keys of each row are configured such that each peripheral key is provided on a substantially flat portion relative to the plane of the keyboard and the one or more intermediate keys on each row are configured such that each intermediate key is provided at a transition gable angle and disposed along a second substantially straight reference line inclined at said transition gable angle with respect to the plane of the keyboard, the transition gable angle being smaller than the gable angle.

Abstract
A plurality of embodiments of improved ergonomic keyboards for interfacing with a user'"'"'s arms, wrists, hands and fingers in a more natural way, i.e., in ways that are optimally suited to human typing. In various non-limiting embodiments, the invention provides optimal finger pressing angles, provides optimal range(s) for “gable” angling, flattens the outer edges of the gable, thins key patterns of split key arrangements, raises (or lowers) the wrist rest to an optimal position, and/or splits the wrist rest into two (or more) components.

17. An alphanumeric QWERTY keyboard having a pre-defined key arrangement, wherein the pre-defined key arrangement for the main QWERTY portion of the keys includes:
at least one key section comprising; a first subset of keys including a plurality of keys, wherein each key of the first subset of keys is provided on a substantially straight plane inclined at a first non-zero gable angle with respect to a plane of the keyboard; wherein said first non-zero gable angle is substantially in the range of about 9 degrees to about 16 degrees; a second subset of one or more keys located outboard of the first subset of keys, wherein each key of the second subset of one or more keys is provided on a plane inclined at a substantially zero gable angle; and an intermediate subset of one or more keys located substantially between the first subset of keys and the second subset of keys; wherein each key of the intermediate subset is provided on a substantially straight plane inclined at a second non-zero gable angle; wherein the second non-zero gable angle is smaller than the first non-zero gable angle provided for the first subset of keys, with respect to a plane of the keyboard. - View Dependent Claims (18)
