Abstract:
A machine implemented method for interpreting handwritten text comprisingwriting said text in sequential time order using a natural language alphabet of mutually independent alphanumeric unistroke symbols to spell out said text at an atomic level, each of said unistroke symbols conforming to a respective graphical specification that includes a stroke direction parameter, some of said unistroke symbols being rotationally differentiated symbols which are characterized by having graphical specifications that differ from each other essentially only on the basis of their respective stroke direction parameters, with said respective stroke direction parameters of all of said rotationally differentiated symbols being rotationally offset from each other by at least 90Â° and no more than 180Â°; signaling a predetermined, symbol independent delimiter between successive ones of said unistroke symbols in said time order; capturing the stroke direction of each of said unistroke symbols as an ordered list of coordinates; disambiguating said unistroke symbols from each other based upon predetermined criteria, including the stroke directions of the respective symbols; wherein the natural language alphabet of mutually independent alphanumeric unistroke symbols is defined by a first set of unistroke symbols and a second set of unistroke symbols.
