A keyboard assembly including a non-linear curved keyboard, a base, and optionally a pointing device such as a trackball. The keyboard comprises an elongated base having an upper non-linear surface and a plurality of keys attached to the upper surface. The plurality of keys is divided into several groups and the geometric relationships between the keys are selected such that to allow maximum use of the thumbs and the fingers, the wrists, the forearms, and the shoulders are in a natural position. An asymmetrical element, supported by asymmetrical theory of nature discussed in I-Ching and embodied in the He Tu diagram, may be introduced into the geometry arrangement. The creation of asymmetrical groups are detailed which allow more ergonomic adjustment of the keys, yet preserve the existing geometry of an original keyboard. A trackball may be added in the space between the upper surface and the elongated base.
An asymmetrical ergonomic keyboard assembly including a non-linear keyboard comprising keys which correspond in designation to a standard keyboard, said keyboard comprising:
The keyboard assembly of 1, wherein said convex curve is asymmetrically curved about said longitudinal axis.
The keyboard assembly of 1, wherein the first group of keys and the second group of keys include alphabetic keys in adjacent rows.
The keyboard assembly of 4, wherein the first group of keys and the second group of keys are not symmetrical along a latitudinal axis on the base.
The keyboard assembly of 6, wherein the tracking device comprises a trackball.
The keyboard assembly of 1, wherein the plurality of rows of keys include numeric keys and functional keys.
The keyboard assembly of 8, wherein the numeric keys and the functional keys are positioned between the first group and the second group of keys.
An asymmetrical ergonomic keyboard assembly including a non-linear keyboard comprising keys which correspond in designation to a standard keyboard, said keyboard comprising:
The keyboard assembly of 10, wherein the first group of keys and the second group of keys include alphabetic keys in adjacent rows.
The keyboard assembly of 11, wherein the first group of keys and the second group of keys are asymmetrical.
The keyboard assembly of 13, wherein the tracking device comprises a trackball.
The keyboard assembly of 13, wherein the tracking device comprises a wireless device.
The keyboard assembly of 10, the plurality of rows of keys includes numeric keys and functional keys.
The keyboard assembly of 16, wherein the numeric keys and the functional keys are positioned between the first group and the second group of keys.
A method for a keyboard assembly for inputting electrical signals into a device with processing capabilities, comprising:
