Abstract:
An ergonomic keyboard, comprising:a keyboard having a plurality of keys with at least one form of functional indicia, said plurality of keys having a substantially central set of keys to form a multi-dexterous keyboard system, wherein said substantially central portion of keys includes a first and second column of keys, and a first and second row of keys for efficiently producing a series of characters, words, and functional commands for subsequent processing; the central set of keys forms a substantially cross pattern having a plurality of intersecting rows and columns of keys to minimize repetitive stress injuries associated with finger extensions for specific keys operatively positioned beyond a hand span of a user; the first column of keys comprising a first series of keys with distinct statistically extrapolated indicia of the most used characters and internet commands disposed on each of said first series of keys; the second column of keys comprising a second series of keys with distinct statistically extrapolated indicia of the most used characters and internet commands disposed on each of said second series of keys; the first row of keys includes a first series of keys with distinct statistically extrapolated indicia of the most used characters and internet commands disposed on each of said first series of keys; said at least one of said series of keys being arranged substantially perpendicular to at least one of said keys in the first column as at least one ergonomic key in common therewith; the second row of keys includes a first series of keys with distinct statistically extrapolated indicia of the most used characters and internet commands disposed on each of said second series of keys; said at least one of said series of keys being arranged substantially perpendicular to at least one of said keys in the second column as at least one ergonomic key in common therewith; whereby said distinct statistically extrapolated indicia comprises at least one of a digraph and a trigraph.
