Abstract
A keyboard has an array of central keys positioned in a generally planar configuration and an array of inwardly-angled keys positioned around and angled toward the central keys to define a pan-like configuration. The keyboard may also comprise an array of outside keys positioned around the inwardly-angled keys. The keyboard may have one or more outwardly angled keys positioned around and angled away from the central keys. The outwardly angled keys are adapted to be accessible by a user'"'"'s thumb, little finger or side of a hand. A keyboard, adapted for use with one hand, comprise four rows of five central keys forming a rectangular outer boundary. Two columns and two rows of 5 inwardly-angled keys surround the central keys. The character-key allocation of the pan-shaped keyboard adapted for use with one hand comprises the re-arrangement of the 3 main rows of 10 keys of a standard keyboard standard. The configuration permits a user to locate his or her hands on the home keys readily, without visual aid by feeling the raised edges of the inwardly-angled keys.
